<br />
Well, that pretty much wraps things up. Today has been a day of packing, more packing, loading, more loading… all followed by the promise of a well-deserved party this evening! <br />
<br />
We would like to finish with a few factoids from the cruise: <br />
<br />
…we travelled approximately 2800 nautical miles… <br />
<br />
…the biologists collected 1124 samples, representing 13 phyla, 11475 individuals, 1634 octocorals and 649 solitary scleractinians!!! <br />
<br />
…the paleoceanographers collected 14398 solitary fossil corals (592 of which were subsampled on board), 106 kg of fossil stylasterids, 512 sponge samples, 418 live bivalves and 2159 fossil bivalves… <br />
<br />
…we recovered 6 sediment cores comprising 333cm of mud… <br />
<br />
…4210 km of multibeam bathymetric data were logged… <br />
<br />
…according to Stian, 723 bowlines were tied (although I’m not quite sure if I should believe this one)… <br />
<br />
…we ate 100kg bacon and 330kg beef… ate 3600 eggs and drank 500 pints of milk… <br />
<br />
…we sent 6 GB of e-mails…. <br />
<br />
…we posted 35 blogs, and 180 photos (not including the daily photos)… <br />
<br />
…thanks for reading them…and a huge thanks to Linda back in Maine for posting all of them! <br />
<br />
It’s been a fantastic cruise – team work, hard work, wonderful people and quite a bit of luck has meant that we’ve had both a successful, and really fun, time. I’d like to thank Laura and Rhian, as well as all the Raytheon staff and ships crew, on behalf of the whole science party for making it all happen so smoothly! <br />

<br />
To begin this blog entry, I would like to thank everyone that made my participation on this cruise possible. With the harvesting of deep-sea biology, fossils, and, of course, the amazing day in the Bransfield Straights, this expedition has been an extraordinary opportunity, which I will never take for granted. <br />
<br />
As this trip winds to an end, we have begun packing, cleaning, and preparing for landfall. We are all working together in one shift again, and everything seems to be going smoothly. With a few moments of spare time, we were able to put science aside for a minute and tour the world below what has been our life for the past month. <br />
<br />
Our tour began by using a stairwell that I only knew existed, but had not yet explored. This stairwell brought us directly beneath our biology laboratory and ended in the main control room for all mechanical operations. The control room overlooks 4 diesel generators used to power the ship, and it is here where one or both of the engineers on duty monitor the mechanical operations of the entire vessel. Under normal conditions, 2 of the 4 generators remain in operation. One generator could handle the electrical demand, but running the second generator ensures a steadier, uninterrupted source of electricity. Next, we listened to facts about the engines responsible for the locomotion of the ship. With 2 separate drive trains, this ship has 2 massive engines on each propeller shaft. During this cruise, only 1 engine per propeller was utilized. Running at 900 rpms each, the 2 engines provide the vessel with a speed of approximately 10-13 knots. Operating all 4 engines does not translate to higher speeds, but provides the necessary momentum needed for the ship to break through sea ice. On an average day at sea, while operating 2 engines, the Palmer consumes 6-8 thousand gallons of fuel per day, roughly 14,000 gallons per day while breaking ice with all 4 engines in operation, and another 1200 gallons per day to supply the 2 electrical generators. Potentially consuming 20,000 gallons of fuel per day, the Palmer is equipped with a 500,000-gallon fuel tank! <br />
<br />
After our explanation of the mechanics of the ship, we were given earplugs and entered the engine room. We walked through a machine shop complete with a sand-blaster, metal lathe, welder, and of course the espresso machine. Next we toured the generator room, and engine room. With so much noise, this part of the tour consisted of taking pictures and communicating with hand gestures. <br />
<br />
The Nathaniel B. Palmer is truly a remarkable piece of engineering, but none of this trip would have been possible without the crew diligently keeping all operations in motions. I would like to close by extending my gratitude to the captain, shipmates, marine technicians, marine science technicians, the kitchen staff, the maintenance staff, and the engineers for their hard work, great attitudes, and tireless service. <br />

<br />
As we near the end of our cruise, I believe we’re all thinking back to our favorite moments, those times of inspiration, excitement and fulfillment. One of the team, Andrea, was inspired to express some of those feelings in poetry, which we would like to share with you today. <br />
<br />
<b>Reflections from a Penguin Spotter </b><br />
<br />
The rumor had spread: two small penguins were seen <br />
Diving and jumping ‘long the waves in between. <br />
My hopes were sky high: I checked the sea every ‘noon <br />
“I wish and I hope I’ll see penguins soon!” <br />
But the days they did past, with no sightings to speak of <br />
Only waves, clouds and sunshine or the stars far above. <br />
‘Til one day our leaders gave us all a great gift: <br />
A Bransfield Strait transit! My spirits did lift. <br />
<br />
<br />
I ran up to the bridge ‘cause I heard exclamation <br />
Scenery and icebergs beyond imagination! <br />
I saw a black dot: “Could it be? Could it be?” <br />
But it was only a fur seal; no penguin for me. <br />
And then I heard words that brought me down low: <br />
“We saw a few penguins twenty minutes ago!” <br />
“You’re kidding!” I cried, “Not again! Why me? <br />
I’ll never see a penguin. It’s my destiny.” <br />
<br />
<br />
The anguish I felt, the utter despair! <br />
I stomped my foot and I pulled on my hair. <br />
My second trip back here and it was not looking good <br />
For me to see a penguin (I tried hard as I could!). <br />
I resigned myself to it and said, “Maybe next time? <br />
Though to travel this far and not see one’s a crime.” <br />
But then to the rescue, came the Third Mate <br />
Who said “I’ll hook you up, if you could just wait.” <br />
<br />
<br />
“Do you see that iceberg straight off the bow? <br />
Use these binoculars. Look there right now!” <br />
I peered through and saw, much to my delight, <br />
Several black creatures on a background of white. <br />
The joy and excitement was full and complete. <br />
This feeling and memory, I will never delete. <br />
But it wasn’t quite over, the joy was not done! <br />
We’d get even closer! We’d have some more fun! <br />
<br />
<br />
We sailed right up close so it was easy to see <br />
Them waddle and stumble as they tried to flee. <br />
Their cute little figures sure made me smile <br />
I could happily watch them for quite a long while. <br />
But the science continues: we have corals to collect <br />
And water and sediment- though I’ll never forget <br />
The feeling I had on my first penguin spotting. <br />
Will I see them again? I’d better start plotting… <br />
<br />

<br />
I like maps. Even as a child I enjoyed following the progress of a car trip on the road map. Now we have a world map on the wall in our house, to more easily visualize where family members are and to fantasize about where we might go someday. As a marine geologist, much of what I do involves learning about where things are relative to each other – is the muddy seafloor only on the continental shelf or does it extend down the slope? Are the mid-ocean ridge basalts exposed on all of the fracture zones? How did this piece of granite (typical of continental crust) get out here into the middle of the Drake Passage (hint… think about icebergs…)? <br />
<br />
Everything we do during this cruise is recorded with the date, time, and position. I use those positions to create maps showing where we have been, what we did while we were there, and what we found. During the cruise, we use these maps to plan where we should take the next samples. After the cruise, I will work with Rhian and Laura to try to understand why corals live in some places and not in others. Maybe one species likes steep slopes with rocky outcrops while another is found only in places where we found mud. <br />
<br />
Just from looking at the ship’s trackline, you can see a story unfolding. In the map below, the colored dots on the black trackline mark each passing hour. Each day has a different color dot. This map shows the 5 days that we worked at Interim Seamount. We arrived from the south in good weather – the hour marks are far apart because we were travelling at 10 knots. Near the center of the map you can see several places where the hour marks are almost on top of each other. These are places where we worked on station or only moved a little for a few hours while dredging or collecting bottom photographs. On the eastern side of the map, there are two almost parallel track line with hour marks pretty far apart – this is where we were collecting multibeam bathymetry data, moving right along at about 8 knots. When we left Interim Seamount, the weather was bad. We had big waves (taller than a 2-story house!) and the ship could only move ahead slowly, at about 3 knots. This is about as fast as you can walk! <br />

<br />
We’ve been on Cape Horn for roughly a day now, and we’re still working on completing our multibeam survey of the area. We’ve hit a patch of rough weather, and so I finally have some time to write a blog! It’s just a few days away from the completion of our science program, and it’s incredible to think about what we’ve been able to accomplish in the past month aboard. A little over a month ago I was graduating from the University of Pittsburgh with my degree in geology, and now here I am in one of the most remote areas of the world. It’s living the geologist’s dream! <br />
<br />
This is my second time aboard the Palmer, the 1st being Laura and Rhians’ pilot program back in 2008. There are many similarities, but in most regards it feels like a brand new experience. While in 2008 we were paired with a geophysics team studying the Scotia arc, now the entire time has been devoted to our paleo and biology sampling. 8 of us aboard were present last time, but the new additions to Team Purple have brought an incredible energy to the ship and to the work that we’ve been doing. It has been really great to be with specialists in so many areas of marine science. As a recent graduate, there’s no better opportunity than to learn coring, water sampling, and dredging from people who have been doing it for quite awhile. <br />
<br />
One of the biggest changes, and in my opinion one of the best, is how the science party on this cruise has been able to engage in a more physical way with the sampling. The back deck is the responsibility of the marine technicians, and it’s great to learn from them what goes in to working on the deck of a research vessel. The last cruise was a fast paced pilot program, whereas this time out every member of the science party has been able to help with launching and recovering equipment and learning how to do a lot of the day-to-day maintenance that marine science equipment requires, on top of doing our science. It makes for a great change of pace to be able to get out of the lab and to get dirty (and wet, and muddy, and cold) terminating cables and hauling dredges out of the water. On days where weather keeps us from sampling, everyone still has a ton of fun learning useful knots and skills like blade sharpening (my personal favorite!). <br />
<br />
The cruise has been a great experience, especially for someone like me who still hasn’t really begun their career. There isn’t a substitute for being with people from all over the world who all do very interesting and different science, and learning what motivated them and what their own experiences getting started in the field has been. I was 19 on the previous cruise, and still wasn’t sure if I wanted to be involved with the earth and marine sciences. But 3 years later, on the same ship, I’ve been writing my first scientific paper and getting advice on graduate school from my friends aboard. There are moments during cruises like this that you realize how lucky you are to be involved in a field like this, and for me it was when we were sailing through the Bransfield Strait. Antarctica on the left, the South Shetlands to the right, and to the front an enormous seal barking at us as we get close to hitting his personal patch of ice. I couldn’t imagine doing anything else. <br />

<div class="MsoNormal"><br />
</div><div class="MsoNormal"><span style="font-family: "Times New Roman";">As we wrap up NBP1103, I thought it would be fun to apply our newfound Antarctic expertise to reflect on what each of packed for this trip. What did people pack that they subsequently didn’t need? Were there items left at home that are now desperately desired? What about items that were surprisingly useful or nice to have?</span></div><div class="MsoNormal"><br />
</div><div class="MsoNormal"><span style="font-family: "Times New Roman";">Approaching a month into the cruise, I can definitively say that I overpacked. Way overpacked. I-could-have-survived-being-abandoned-in-the-wild-for-a-year overpacked. Some things have been worthwhile; for example I brought 14 pairs of socks I am glad for all of them. But six short-sleeve t-shirts? Did I think I was going to the tropics? With some rare exceptions I’ve uniformly worn long-sleeve shirts. In fact, most of the clothing I wear was issued to me in Punta Arenas: our designated “Extreme Cold Weather” gear. It turns out the staff who live and work in Antarctica know exactly what you’ll need and, in my experience, the issue clothing has completely replaced my own over-stuffed luggage.</span></div><div class="MsoNormal"><br />
</div><div class="MsoNormal"><span style="font-family: "Times New Roman";">I decided to ask around on the ship the three questions I posed above. The range of Antarctic packing experience in the interviewees ranges from none (ie: me!) to quite a lot (our Raytheon staff, many of whom only bring down a single backpack and count on personal and issued gear left in Punta Arenas after their last trip). So, if you find yourself packing for an Antarctic trip anytime soon, best take a look at this list of packing regrets, surprises, and recommendations!</span></div><div class="MsoNormal"><br />

We have just left our penultimate sampling site, Sars Seamount. Sars Seamount rises up dramatically from the abyssal seafloor, from 4000m up to just 500m below the sea surface. The flanks of the mountain are rugged: covered in pinnacles, ridges and steep cliffs. If it was on land it would be a popular site for extreme mountaineers and climbers. Strangely the top of Sars is completely flat, so flat in fact that we were able to trawl across the top collecting all sorts of interesting live animals and fossil remains. <br />
<br />
One of the reasons I was so interested to come to Sars is that it has all these features that rise to different depths, so we can find a place to sample from shallow to deep whatever the wind direction. We spent nearly a week at Sars, and during that time we have taken photos, collected water, collected bathymetric data and sampled the seafloor fauna. The photographs have blown me away – they are crystal clear glimpses into another world – we are getting a four dimensional view of Sars. Not only can we see the bathymetry – we can see the animals that are living there today – and the fossil remains of animals that inhabited the seamount tens to hundreds of thousands of years ago. Even here, so far from any city we saw signs of human activity: a rope lying on the seafloor encrusted with seafloor animals – a reminder of our ability to impact all parts of the Earth – even deep below the sea surface. <br />
<br />
Perhaps not surprising we saw and collected the most abundant and diverse samples at the shallower depths on the seamount. When we deploy equipment over the side we let it out at 30m per minute, so it can take a many hours to collect samples from deep sites. Despite the long times, and the lower recovery rates in deep water we worked hard to sample at 2000m water depth. In the end we were able to collect fossil coral remains from the peak of the seamount all the way down to 2000m. Together these samples will let us piece together information on the vertical structure of the water column here at Sars in the past, and compare it to the ocean currents that we have observed here today. <br />
<br />
I am sad to be leaving Sars, it was a wonderful place to collect samples. But today we are moving to new adventures on the shelf of Cape Horn. <br />
<br />
Wish us luck on our last week of sampling. <br />

<br />
Hi, my name is Mariana. I’m a biologist; I work in the benthos lab of the National Institute of Fisheries Research and Development (INIDEP). I have a postdoctoral fellowship (CONICET) since 2010. I am interested in echinoderms such as starfish, sea urchins, and brittlestars, and know about their distribution patterns and taxonomy along the shelf-break front in the Argentine Sea. I was selected to participate in this cruise as an Argentinean observer. Although this is not my first research cruise I was very nervous at first. I have never been a long time at sea, and in addition it would be in the Drake Passage, well-known for its rough seas and strong winds! Besides I have to be a month with new people who speak a different language! <br />
<br />
My nervousness disappeared when we left Punta Arenas, when I saw that all were very excited for this new experience. During the first days I met all the people on board, all of them with a strong feeling of camaraderie ready to do their best so all the cruise would be successful; What can I do? How can I help you? And all eager for knowledge – What is it? How does it work? And what is that for? I am in the day watch with other two biologists, Chris and Mercer; we sort and preserve biological material that we collect with dredges. I learned a little more about deep sea corals, live and fossils, and I helped to indentify several echinoderm species, some of them were similar to the species I work with! Some of the species I observed during this cruise, I thought that I would only see in pictures! <br />
<br />
Antarctica! We get to the southernmost point in the whole cruise! I don´t believe that the thousands of pictures and videos that we got, can show the emotion, happiness and beauty of that day! I got up very early that day when I saw pancake ice by the window of my cabin, there was no time to lose! The emotion of the first iceberg! Whales! Seals! Penguins! No words or pictures can explain all these sensations. <br />
<br />
We are now heading north and counting down the days for the end of the cruise. Drake Passage showed us a little more of its nature. Although some stations were delayed, soon, as scheduled, we will be in port with all goals reached. After all these days, I think that my initial nervousness were only normal feelings facing a new life experience! Luckily - science and laughs, stories and jokes that make you feel good, are the same in any language! <br />

<i>Hola, mi nombre es Mariana, soy bióloga; trabajo en el laboratorio de bentos del Instituto Nacional de Investigaciones y Desarrollo Pesquero (INIDEP); tengo una beca postdoctoral (CONICET) desde el año 2010. Actualmente estoy trabajando en taxonomía y patrones de distribución de equinodermos a lo largo del frente de talud del Mar Argentino. Fui invitada a participar en esta campaña como observadora argentina. Al principio estaba nerviosa dado que, si bien no es mi primera campaña de investigación, nunca estuve embarcada tanto tiempo ni en el Pasaje de Drake! Conocido por sus grandes olas y fuertes vientos! Además de tener que estar un mes con gente que uno no conoce y con un idioma diferente! <br />
<br />
Mis nervios desaparecieron cuando dejamos Punta Arenas y vi que todos estaban igual de ansiosos por esta nueva experiencia. Con el correr de los días pude ir conociendo cada una de las personas en el barco, todos con un gran sentido de camaradería para lograr que todo salga bien, no todos los días se tiene la oportunidad de estar en una campaña de investigación en estas latitudes!! Qué hago? En que puedo ayudarte? Además todos con ganas de aprender Qué es? Como funciona? Para qué sirve? Participo en la guardia de día junto con otros dos biólogos, Chris y Mercer, separamos, clasificamos y guardamos el material biológico que colectamos con los distintos equipos. Aprendí un poco más sobre corales de profundidad, vivos y fósiles, y ayudé también a identificar algunas especies de equinodermos que resultaron similares a muchas con las que trabajo! Pude ver especies que pensé que solo las conocería por fotos! <br />
<br />
Antártida! Llegamos al punto más austral de toda la campaña! No creo que las miles de fotos y videos que tomamos puedan mostrar la emoción, alegría y belleza de ese día! Por supuesto fue el día que más temprano me levante, cuando vi por la ventana de mi camarote que había hielo en el agua, no había tiempo para perder! La emoción del primer iceberg! Ballenas! Focas! Pingüinos! No hay palabras ni imágenes que puedan explicar todas esas sensaciones. <br />
<br />
Ahora ya con rumbo norte y en cuenta regresiva. El Pasaje de Drake nos mostró un poco más de su naturaleza y aunque algunos lances fueron retrasados por su causa, en breve y en el día pautado estaremos en puerto con todos los objetivos cumplidos. Después de todos estos días creo que mis nervios iniciales fueron solo los normales frente a una nueva experiencia de vida! - por suerte tanto la ciencia como las risas, historias y bromas que hacen que uno se sienta bien, son las mismas cualquiera que sea el idioma! <br />

<br />
The WHOI Tow Cam is a multiple instrumental package mounted onto an aluminum frame. Along with the two separate camera systems there are: Niskin Bottles for water collection, altimeters for altitude, standard CTD (see Tina’s post), batteries, data link, lasers for a measurement scale, and a whole lot of wires! The primary use of this sled is for underwater photography. Attached to the frame are two cameras that have the ability to record over 4000 images on one tow alone. <br />
<br />
One camera is called the DSPL, the other OIS. The DSPL produces an image with a large footprint. The OIS produces an image that has 4 times the resolution than the DSPL but the footprint of the image is much smaller. Another ingredient to this camera system is the data link, which gives us the ability to see the pictures in real time on a monitor. The data link provides ethernet up the sea cable. Which makes the camera operation exciting and fun for everybody! <br />
<br />
Each camera is set up to take pictures at 10-second intervals. Tow Cam operations can only happen when conditions (weather) are ideal. If the ship’s heave is too great we run the risk of “crashing” the frame and cameras on the bottom. If the winds are too high it’s difficult for the ship to hold position for deployment and recovery. And this is a risk we are NOT willing to take! <br />
<br />
An average deployment and recovery time is about 6-10 hours. During this process another member of the science party is plotting the ships position, speed, depth of frame, and altitude every 5 minutes. Once the frame is on board, the pictures are downloaded from the cameras and backed up, which could range from an hour to five, depending on how many pictures are on the camera and how well the coffee has been flowing that day. <br />
<br />
Luckily, both ships crew and officers have been unbelievable at handling the ship during operations, and controlling the over the side operations safely so we can optimize our time with the science (And there is a lot). <br />
<br />
When I said “TOW CAM!”, NPB 11-03 participants said: <br />
<br />
“Yea, Lets Do it!”… “Don’t stare at the lasers”… “GO CAM”… “live feed from Tow Cam is awesome”… “far out images”… “what I have seen is pretty cool, watch for hours, plotting lots of locations”… “brings up a lot of water”… “makes me think of my friends in the hydro lab”… “cool to watch deployment and recovery”… “mind blowing images”… “exciting to see what undisturbed habitats and life looks like 3000 meters down”… “it’s heavy”…“useful”… “crisp”… “weather”… “Bonanza”… “awesome”… “cool”… “lots of water”…“take it back out we need to rinse it off”…“amazing advancements in supportive science”… “fun seeing the real time imagery”… “backing up lots and lots of pictures”… “Daffy Duck”…“lots of logging and pictures”. <br />

<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjXzavESxKBn_BFbw3udWQfoKF4CQPUDfWoLJEC3gueTLWsVo9V6MgzI3OPhpYBrhYdLt-ToeCA-JS6wGHZ-JLJCSRX6X_VmlYn5lFa6PT1DVuC7Tolj_dO9GPe6pvX_I5OpUfvmmt8Xxau/s1600/image6-june1.jpg"></a><br />
As a researcher investigating deep-sea and cold-water organisms, a large part of my life is spent at sea collecting samples and data to be analyzed once we head back to shore. In fact, by the end of this cruise I will have spent 685 days at sea since 2000, the year I started my Ph.D. at the Southampton Oceanography Center in the UK. That’s just shy of two whole years I’ve spent on the rolling ocean, and a long time to be away from home, friends and family. Because most of my cruises go to remote places, they also tend to be long, just a small handful of the 31 cruises I’ve been on have been less than 3 weeks, and 5 weeks is more the norm. This is nothing compared to the Raytheon Polar Services Technicians we have out here though, or the crew of the ARV NB Palmer, many of whom spend many months at a time down here. <br />
<br />
So how do people stay connected at sea and what reminders of home do they bring? <br />
<br />
For me it’s pictures. On the wall in front of me right now are pictures of my little niece and my dog, and a drawing my 6yr old neighbor drew and emailed out to me (Hi Karter!). On my computer I frequently wander through photos of my last trip to the UK (where i’m from), my nephew and niece, trips with friends and photos of my new home in Maine. <br />
<br />
Marshall (who often spends more time at sea than on land!) brings along his coffee maker and mug for down in the lab and a personal throw rug and folding chair for up in his bunk-room. “Just something to make the space more personal and cover the cold floor” he says. <br />
<br />
For George it’s not so much things, but phone calls that keep him in the loop (and who could expect less from our Electronics Technician). Reliable satellite phones are often still rare at sea, but we’re lucky on the ARV NB Palmer to have a “moral phone”, for those times you just need to check in. George calls his daughters and mother to keep in touch with what’s happening in the ‘real world’. <br />
<br />
As we start to reach the homestretch of this cruise, it certainly makes me think more of home and wondering what’s been happening back there the last 3 weeks. Is it warm in Maine now? Are the black flies gone? What is under all those snow piles I left behind? How much paperwork is piled on my desk awaiting my return? I guess some things I’m more excited about than others….. <br />

<br />
How many doctors (of philosophy) does it take to ensure a successful research cruise? Well, that depends on whether you take the census at the front end or back end of the cruise. One of us (myself) boarded this cruise as a PhD candidate, and will return as a doctor. Two other biologists, Michelle from Imperial College London and Eric from the University of Louisiana at Lafayette, submitted their dissertation to their advisors only moments before and during the cruise respectively. Although a few years away from being a doctor, biologist Sebastian successfully completed his undergraduate degree at the University of Maine only days before departing for Punta Arenas, Chile. <br />
<br />
Eric and Michelle lead the midnight to noon biology shift while Mercer and Chris (graduate student at the University of Maine) head the noon to midnight shift. Sebastian supports the former shift, while Argentinean observer Mariana supports the latter. Both parties are responsible for processing animals obtained during overboard operations. ‘Processing’ is a broad term that refers to the following activities: <br />
<br />
1) Mixing formaldehyde with seawater to make formalin, a (nasty) reagent that preserves morphological structures very well, but not DNA. <br />
<br />
2) Mixing ethanol with pure water to make a reagent that preserves DNA (i.e., genetic information). Ethanol is very dry and distorts morphological structures. <br />
<br />
3) Filling 20+ buckets with ice-cold seawater for temporary specimen storage <br />
<br />
4) Aiding in the deployment and recovery of sampling gear. <br />
<br />
5) Removing large boulders from the opening of sampling gear to allow the bulk of the material (generally much smaller) to be removed. <br />
<br />
6) Removing mud and other sediment from the trawled material using a high-pressure seawater hose in combination with sieves of different mesh size <br />
<br />
7) Conducting a gross sort of the trawled material on the back deck of the ship and placing animals into ~8 buckets based on very broad categories (e.g., cnidarians, crustaceans, sponges, mollusks, worms, fish, etc.). <br />
<br />
8) Moving the buckets, filled with animals, into the first wet lab for sorting into more defined groups (e.g., soft corals vs. hard corals, shrimp vs. crabs, etc.); each specific group is placed in its own bucket of ice-cold seawater. <br />
<br />
9) Moving the ever-growing number of buckets to a second wet lab for identification and preservation of the animals contained within them. <br />
<br />
10) Laugh politely, but nervously, when a paleoceanographer asks you “What is that?” because you have no clue. Stumped by external features, you begin dissecting the animal, only to become more confused. Now the paleoceanographer asks “What was that?” You still have no clue. Perhaps the animal in new to science. Perhaps it’s simply new to you. <br />
<br />
11) Count the number of individuals within each type or species. <br />
<br />
12) Photograph a representative of each type or species. <br />
<br />
13) Subsample select individuals twice for subsequent DNA analysis. Place subsamples into screw cap tubes filled with either ethanol or seawater. Tag select individual using fishing line and an archival-quality paper label. Take photograph of individual that was subsampled. Run sample to the -80°C freezer located in the aft dry lab. <br />
<br />
14) Determine if all the individuals of a single type or species will fit better in a bottle or jar, or if the specimens are destined for the -80°C freezer, determine what size Whirl-Pak should they be placed in. <br />
<br />
15) Label the outside of each bottle, jar, or Whirl-Pak appropriately. <br />
<br />
16) Panic because the principle investigators are bringing yet another dredge to the surface before this one, or the one before it, are processed. <br />
<br />
17) Include an archive-quality paper label inside of each container that contains the same information as written on the outside of the container. <br />
<br />
18) Cringe as someone picks up a container you just wrote on and smears the label. <br />
<br />
19) Place all individuals of a single type or species into the container. <br />
<br />
20) Walk the animals from the second wet lab to the biology lab, where the preservatives noted above are stored in a fume hood. <br />
<br />
21) Release expletives as you realize the last shift left you with no formalin or ethanol. <br />
<br />
22) Cringe as you walk back to the wet lab and realize that you forgot to include the archive-quality paper label in the specimen container that now contains preservative. <br />
<br />
23) Realize that the next trawl is already on deck (and full of new animals to process). Panic. Contain panic. Panic. <br />
<br />
24) Look outside and realize you’re in the Drake Passage. Not only are you overwhelmed with samples, but you are in the roughest seas in the world trying to process them. Pray for a weather delay in overboard operations. Prayer granted…. <br />

<br />
To celebrate Memorial Day, today’s blog is a selection of one-line reactions from many of our science party to the things they have seen and experienced thus far on this expedition. <br />
<br />
<div style="text-align: center;">“So many amazing experiences, trawls, dredges, and multibeam. Oh my!” <br />
Shannon </div><div style="text-align: center;"><br />
<br />
“A terrific selection of dedicated scientists, and they are slightly mad, enthusiastic and great fun too (plus penguins, fur seals and pack ice); who could ask for more from an expedition?” <br />
Michelle </div><div style="text-align: center;"><br />

<br />
<br />
“Never a dull day with this group and hoping for some more fun times in the future!” <br />
Sebastian <br />
<br />
<br />
“So far, the new multibeam data we have collected has changed my interpretation of the geology of Burdwood Bank, confirmed what I knew about the Shackleton Fracture Zone, and given me new insight into the morphology of the Antarctic Shelf – not bad for two and a half weeks!” <br />
Kathy <br />
<br />
<br />
“Incredible/hard work/excellent – couldn´t be better/awesome, unbelievable!!!” <br />

<br />
On the Drake Passage Expedition, we use a variety of equipments, including tow- and drop-cams to get images from the seafloor (see Rhian’s post), and the CTD to get samples from the water column (see Tina’s post). Specimens, alive and fossil, organic and inorganic, are sampled using trawls and dredges. While this relatively simple equipment has been used since the infancy of deep-sea science, it is reliable, efficient, and can be deployed in a variety of situations from different types of research vessels. While the trawl works very well on soft substrates, the dredge is well adapted to sampling on rugged terrain (for example, on the summit and slope of a seamount). The dredge is also safer to use when we don’t know exactly what the area is like, and it is the instrument that we tend to use the most. During a typical operation, the dredge is dropped straight to the bottom, and after giving the wire some slack, the boat slowly advances in a straight line, paying wire at the same time. After about 30 minutes, the boat stops, and we slowly pull the dredge back in. This is when the sampling of the sea floor happens, and when we have to be particularly vigilant. While being pulled, the dredge might be caught on some feature (e.g. boulder). If the dredge does not continue its course, something will eventually break, and we might lose our precious equipment. The entire dredging operation can last from about an hour to an entire day, depending on the depth at which we sample. <br />
<br />
Us deep-sea biologists in-training need to know how and when to use the different tools available, yet this is not the kind of knowledge that we get from the classroom. Here, we learn by doing, and we are very lucky to have chief scientists that make sure that everyone on the science team gets a chance to learn some about everything. <br />
<br />
A few days ago, Rhian let me “run my first dredge.” In the dry lab, I face a wall of flat screens displaying information (among other things) on the ship course, and information on the winch, the hauling device that connects us to the dredge. Once the dredge is laid on the seafloor, we radio the winch room to start paying out wire at 30 m/min, and the bridge to keep the boat advancing at the same speed, so the wire can be neatly laid on the seafloor behind us. Once our transect is laid out, it’s time to sample some corals. “Winch room, winch room – dry lab. Please start hauling in at one zero.” I watch the tension of the cable: we don’t want to lose the dredge to a big boulder. The tension of the cable is expected to vary between 2,000 and 5,000 pounds; above that: the cable is under significant tension and we might have to stop the winch. A few minutes pass by. Tension is stable under 5,000 pounds. Michelle brings us some cobbler. Woohoo! Peach! Cable tension spikes. Eric’s blood pressure too. It’s alright, says Rhian. We probably hit a rock. Enjoying the cobbler. Tension spikes. 7,500. Ok – no more cobbler... All eyes on monitors. Tension spikes again to 9,200 pounds. We get concerned, because the safety ring that links cable and dredge is designed to snap at 9,000 pounds… We might be dragging the dredge by one side only! Tension is low again… and spikes to 11,400! We must be sampling on very rugged terrain! This is nerve-racking… Have we lost the equipment? At the end of our transect we haul the wire back in, hoping that the dredge is still attached. On the freezing deck, we are burning of anticipation. The water surface bubbles… The dredge comes out in one piece! It is full of rocks and specimens! <br />

My name is Kate, and I’m a postdoctoral researcher at Woods Hole Oceanographic Institution. I was on the 2008 cruise with Laura and Rhian, which happened a mere month or so after I finished my PhD. Although it’s always difficult to be away from my family and friends (especially as I got married in January this year!), I’m really excited to have such a wonderful opportunity to return to the ARV N.B. Palmer with a few years more experience. In fact, when I walked on the ship on the first day, the smell of the labs and the decks brought it all back to me. I felt as if I had never left. <br />
<br />
On the cruise, I’m here to collect deep-sea sponges, as well as help out the paleoceanography and biology teams with all the other science going on. My work involves using the chemistry of deep-sea sponge skeletons to tell us about past ocean chemistry. Sponges make their skeletons from glassy needles, called spicules. I collected sponges on the last cruise, in 2008, and found that the chemistry of these spicules relates to the amount of nutrients in the water in which they grew. This means that the fossil skeletons, picked out of deep-sea sediment cores, can be used to reconstruct past nutrient levels in deep waters. It’s these nutrients that upwell to the surface and are essential for the growth of algae, which take up carbon dioxide from the atmosphere. Understanding how their supply of food has changed in the past is really important for understanding the role that algae play in changes in greenhouse gases and climate. It’s really exciting to be carrying out such novel work, but a lot more studying needs to be done to understand thoroughly what is going on, and why spicule chemistry behaves this way. This trip I’ll be collecting more sponges, and sediments that contain fossil spicules, to start piecing together more about what controls sponge chemistry, and how seawater nutrients have changed in the past. <br />
<br />
And I’m also helping to organize this blog every day! I helped with the website we ran on the last cruise, and enjoyed it so much I was really keen to get involved again. I hope you’re enjoying them! <br />
<br />
At the moment, we’re transiting to Sars Seamount in the middle of the Drake Passage. It’s only about 100 nautical miles from Interim Seamount, but we’ve also been having some rather bad weather so we can only go very slowly. I’m particularly excited about getting to Sars, however, because last time we were there in 2008 it proved itself to be “sponge wonderland”. Not only did we collect some fantastic corals, but we also found the mother lode of sponges. Let’s see what we can find this time around… <br />

Hi everyone, my name is David and I’m excited to be participating in my first research cruise. I was first introduced to oceanography, specifically cold-water corals, as a summer intern in 2009 by our chief scientist, Laura Robinson. Since then I’ve continued focusing on coral geochemistry and was quick to jump on an opportunity to study them in their natural habitat. <br />
<br />
My background is in chemistry, which I use as a tool for examining and understanding the world around us. In particular, I study the chemical composition of fossil coral skeletons. As coral geoscientists, it’s our hope that the chemistry recorded in coral skeletons is representative of the chemistry of the ocean water in which the corals grew. If so, then we can use ancient corals as archives of the ingredients that made up the ocean in the past. Coupled with observations of how the oceans work today, we’d be well on our way to unraveling how one of our planet’s most dynamic and complex systems behaves! <br />
<br />
One way we can test whether coral skeletons record the composition of the seawater around them is to analyze modern corals and compare them to water samples that we obtain while on cruises like this one. In her blog post, Tina mentioned that one measurement we make onboard is of seawater alkalinity. One reason we measure alkalinity is so that when the modern corals we’re collecting go back to various labs for analysis, we can compare their skeletal composition to the alkalinity of the water bathing the corals as they grow. If we find a strong correlation, then we know we’ve found a good “proxy” for discovering what seawater alkalinity was like in the past – we would just have to look in the skeletons of ancient corals! <br />
<br />
You might be wondering, `what is alkalinity?` You might have heard of pH, which is a measure of the acidity of water. Alkalinity is the acid neutralizing capacity of that same water. For example, pretend I have two buckets of water at the same neutral pH. In the first bucket I pour in some sulfuric acid and the pH drops really low, which is to say the bucket became highly acidic. In the second bucket I pour in the same amount of sulfuric acid, but the pH doesn’t change all that much. We would say that the second bucket had a higher acid neutralizing capacity, or that the second bucket had higher alkalinity. <br />
<br />
Besides getting excited about alkalinity, I’m enjoying helping out with every odd job I can on the boat. My favorite task is going on the back deck of the boat whenever new samples come up from the seafloor. For safety and warmth everyone has to wear orange “float coats” and hardhats. It’s one of the few times every day I get outdoors and have a chance to marvel at the endless waves around us. <br />

<br />
I don’t think it really hit that I was in for a once in a life-time experience until I was flying over Patagonia on the way to Punta Arenas and saw the Andes breaking through the cloud cover. This is my first scientific cruise and the longest time I’ve ever spent out at sea. Needless to say I was a bit concerned having heard stories of the violent weather and high seas of the Drake Passage as well as the intense cold I was most likely going to experience being so close to Antarctica. The nervousness left relatively quickly, however, once the work began and we had set sail. <br />
<br />
Being able to be a part of the many different research goals while being on the same ship and working cooperatively with different fields of study has been one of the most rewarding experiences I’ve had so far on the Nathaniel B. Palmer. The size of the crew requires that everyone on shift be prepared to help one another with whatever needs to be done, regardless of previous experience. Although my main focus lies in collecting, identifying, and storing the organisms we find using Blake trawls and Heine Dredges I have been introduced to a wide array of other jobs while on shift. I have helped collect and subsample fossil corals brought in from Heine dredges as well as gain a basic understanding of the multibeam program CARIS we use for underwater mapping. The theme of cooperation is omnipresent on the ship and we often find ourselves helping the Marine Technicians whenever we can while on deck to help with safety or help ease the load of bringing in a Box-Core Sample. <br />
<br />
Working and collaborating together on the same team with many different goals has been an eye opening experience for me. Many of the biological samples collected will go to other scientists, whose research focuses and depends on the specific organisms we collect while on our cruise. There has been a general feeling of camaraderie on the ship with many laughs to be had and a common goal to do the best we can in order to help one another. Overall the experience has been a great one and I look forward to the next half of the cruise being as good, if not better than the first half. <br />

<br />
When you flip an hourglass over you´ll notice that the first grains of sand that fall through its neck will stay at the bottom of the pile of sand that forms as time goes by. In the ocean, sediments supplied by rivers, icebergs, wind and organisms sink to the ocean floor all the time, and like in an hourglass, new particles pile up on top of sediments deposited in previous times. <br />
<br />
This convenient arrangement acts as a natural recording device to preserve information about past environmental conditions on Earth. To unravel this signal encrypted in sediments, we first need to collect an undisturbed sample of sediments from the ocean floor, where older sediments are still at the bottom and younger ones at the top. We use devices called sediment corers, which essentially are tubes or boxes that are lowered to the bottom, sink on the ocean floor, and are pulled back onto the ship hopefully keeping an intact sample of the ocean floor within. <br />
<br />
Once a core is on board or in the lab, we take samples that were deposited in a period of interest and take sophisticated measurements that will translate information about past ocean temperature, acidity, current strength, chemistry, etc. To be able to do this we need to obtain the sediment age. There are many ways to know how long ago sediments, and the information contained in them, were deposited. Some require a simple count, like in sediments that are deposited regularly following seasons, where one or two clear distinct layers mark each year. Unfortunately, this is not often the case, and other methods such as radiocarbon (or Carbon 14) dating, are used. Typically, sand-size skeletons of organisms called foraminifera, which are made of calcium carbonate, are used. However, burrowing organisms living on the ocean floor may slightly mix the sediments, making accurate dating of sediments a bit more difficult. <br />
<br />
One of the goals already accomplished in this cruise was to obtain fossil corals from sediment cores. These corals may be suitable for dating by radiocarbon and other chemical elements. Corals are 20 to 400 times larger than foraminifera, and therefore much more difficult to be mixed by burrowing organisms, which may improve dating accuracy. If successful, it will help us know the age of the sediments that surround them, know how long ago corals lived in this area, and if they settled or became extinct associated with a change in oceanographic or climatic conditions. Time will tell us. <br />

<i>25 Mayo <br />
<br />
Imagina un reloj de arena, cuyos granos se deslizan continuamente por su estrecho cuello, formando un montón en su base a medida que pasa el tiempo. Los primeros granos, en los primeros segundos, quedarán atrapados en la base del depósito que se forma y nos dice cuanto tiempo ha transcurrido. En el océano, los sedimentos aportados por los ríos, los icebergs, el viento y las criaturas que viven en él se depositan en el fondo continuamente, y, como en un reloj de arena, las partículas de sedimento más recientes se depositan encima de las depositadas en períodos anteriores. </i> <i><br />
<br />
Esta conveniente organización vertical permite que los sedimentos actúen como un dispositivo natural de grabación capaz de preservar información acerca de las condiciones ambientales en el pasado de la Tierra. Para desentrañar esta señal encriptada en los sedimentos necesitamos extraer muestras de sedimentos sin perturbar del fondo oceánico, en las que los sedimentos más antiguos se encuentren todavía en la parte inferior, y los más recientes en la superior. Para esta tarea empleamos unos instrumentos llamados sacatestigos de sedimento, o “corers”. Estos dispositivos son en esencia unos tubos o cajas que se hacen descender hasta el fondo marino, se introducen en el sedimento, y se vuelven a subir a bordo esperando que contengan en su interior una muestra intacta de sedimentos del fondo oceánico. </i> <i><br />
<br />
Con el testigo a bordo o ya en el laboratorio, extraemos muestras de sedimentos depositados en el período de interés y llevamos a cabo medidas sofisticadas que se traducirán en información acerca de la temperatura del océano, su acidez, corrientes, composición química, etc., en el pasado. Para conseguir esto es necesario conocer la edad del sedimento. Existen muchas maneras para saber el tiempo transcurrido desde que se depositó un sedimento y la información que contiene. Algunos de estos métodos requieren un simple contaje, como en sedimentos que depositados periódicamente siguiendo el ritmo de las estaciones, en los que cada año se reconoce por una o dos capas de sedimentos bien diferenciadas. Sin embargo, este tipo de sedimentos no se encuentran con frecuencia, y es necesario recurrir a otros métodos como la datación por radiocarbono (Carbono 14). Para ello generalmente se emplea el esqueleto compuesto de carbonato cálcico de pequeños organismos llamados foraminíferos. Desafortunadamente, los organismos marinos que viven en el fondo mezclan el sedimento dificultando la obtención de edades precisas. </i> <i><br />
<br />
Uno de los objetivos que ya se han cumplido en esta expedición es la obtención de corales fósiles en testigos de sedimentos, ya que estos corales se pueden datar por radiocarbono y otros elementos químicos. Comparados con los foraminíferos, los corales son de 20 a 400 veces más grandes, de modo que su removilización y mezcla por los organismos del fondo marino es mínima, lo que mejora la exactitud de las edades obtenidas en ellos. Si esta datación es exitosa, nos permitirá conocer la edad de los sedimentos que los contienen, desde cuando hay corales en la zona estudiada, y si su establecimiento o extinción están asociadas con algún cambio en las condiciones oceanográficas o climáticas. El tiempo nos lo dirá. </i> <i><br />

<br />
Well, first off, night watch is a bit of a misnomer, as our shift starts at midnight (12 am) and ends at noon (12 pm), so actually we only work during the morning hours! But waking up at 11:00 PM to pitch black skies is enough to warrant its name! <br />
<br />
The science team on our cruise is split between two watches to allow us to continue our work 24-hours a day: noon-midnight and midnight-noon. The night watch starts the day with ‘midrats’ (short for ‘midnight rations’) at 11:30 PM. We devour some combination of eggs, cereal, oatmeal, or left-overs from the day’s dinner. We are supposed to report for duty fifteen minutes before our shift starts to get briefed on what has happened by the day watch, leaving us only 15 minutes to eat. For slow-eaters like myself, this is quite the challenge! <br />
<br />
Although we are forced into bizarre sleeping patterns, there are a lot of benefits to being on the night watch. One of the great things about being on night watch is that, in general, it is a quieter watch. There are fewer people awake during our hours, and so the hustle and bustle of the ship is not as pronounced as it is during the day watch. The quietest hours are between 2 AM and 7 AM, after the energetic day watchers have retired to bed and before the early-risers wake up. This stretch can be a long one in the rare instance when we are transiting and don’t have dredges to sort or water to analyze. But regardless of how busy we are during this time period, we inevitably find everyone sneaking back to the mess hall for a snack at around 4 AM (see blog from May 18 for a description of the lovely treats we have on board!). This cake-break is never planned, and never really even discussed. Rather, this serendipitous gathering of night-watchers is met instead with knowing glances of shared hunger; there is a marathon stretch between our first two served meals of 11:30 PM midrats (breakfast) and 7:30 AM breakfast (breakfast #2 of the day - we eat a lot of eggs and bacon)! <br />
<br />
Another great aspect of night watch is that during the wee hours of the morning, to keep ourselves awake, the jokes start to appear - funny dress and glowsticks, singing and dancing on deck while we await an upcoming dredge, and just general silliness all around to break up the tiredness. <br />
<br />
But by far the absolute best thing about night watch is the sunrises. Rumor has it they are WAY better than the sunsets!! <br />

<br />
After having had a fabulous passage through the Bransfield Straits yesterday, we reached our next station on the Antarctic Shelf in the early morning hours. It is a station where Rhian has done a lot of work in the past, and hence we had some pre-warning of what to expect: lots of living organisms and even more mud! <br />
<br />
Having spent the last week with bringing up dredges with rocks, fossil corals, and some small organisms, this was quite a change. It was a day where everybody got properly dirty, wet, and cold. But it also was a lot of fun. We switched our sampling gear from the metal dredge we typically use to a trawl with a net. This way we could bring it up on deck and open a knot at the bottom to empty some tens of kilograms of mud into a big bucket. Then the real fun began: two people shuffled the mud in portions of a few kilograms on a large sieve, two people sprayed the mud mount with water hoses, and two more people picked out any live organisms, and put them in buckets of water. <br />
<br />
Sounds organised? In theory ... in practise everybody was very muddy and wet at the end of the exercise – but with a big smile on their face. Once you are soaked and muddy, it simply does not matter anymore how much water and mud hits you. On the science side we found lots of good material, such as really big live cold-water corals, giant sea cucumbers, and more. We collected a muddy 1.5 meters of Kasten core, and took successful camera pictures of the muddy ocean floor. It was a fun day!<br />

The back deck is a busy place when sampling gear is going down or coming up and everyone has a job to do – hooking the gear, holding a line, getting sampling buckets and tools ready, or shuffling samples from the back deck to sorting tables. Here the night team bring a box core onboard in the rolling waves. (R. Waller).<br />

We were looking out into the Bransfield Straights, the channel of water between the West Antarctic Peninsula and its companion chain of islands. After a break of nearly four years, and thinking that I would never be back to the Peninsula, I was able to look out on the mountains and glaciers of Antarctica, King George and Nelson Islands. And it left me, and all my new and old friends from NBP1103, without a coherent sentence. We have been so lucky today in being able to transit between study sites in clear weather through sea-ice, between icebergs, and in the company of Adelie penguins, minke whales, fur seals and a host of seabirds.</div><div style="font-family: inherit;"><br />

<br />
I study deep-sea octocorals, primarily Primnoidae, a family of coral whose polyps are covered with an armour of protective calcium carbonate scales (see the first image of polyps of Thouarella chilensis taken through a Scanning Electron Microscope). They occur globally but are most common in the sub-Antarctic, where we are now. In stark contrast to Eric, I have been inundated with them (a few colonies of Thouarella chilensis we have sampled are in the second image)! The shelf areas we have been sampling have lots of nutrients and fast flowing water, ideal for Primnoidae (in fact most octocorals…apart from Eric’s Chrysogorgidae that is!). One haul brought in several bucket loads. So far we have sampled 12 different genera, probably representing around 20 species. Of these at least two are new to science, a very exciting prospect.<br />
<br />
I have just finished my PhD studying deep-sea octocorals from around South Georgia (to the north east of where we are right now) so samples from the opposite side of the Drake Passage and into its depths will make an interesting contrast. I use genetics to study diversity in octocorals and I would like to see if there are genetic differences from octocorals found on each side of the Drake Passage, as given its size and strength this rapidly moving water mass may act as a barrier to gene flow.<br />
<br />
For the time being, as we continue to sample more southerly and deeper waters, I wait excitedly to see what other new octocorals come up in the next haul…<br />

May 19th<br />
<br />
I study chrysogorgiid corals (http://deepseacoral.lifedesks.org/pages/63), a group of predominantly deep-sea corals found down to 4200 m depth. Chrysogorgiids are diverse (about 100 species described) and found in all major oceans, within a broad latitudinal range (see figure). Despite this broad distribution, chrysogorgiids are rare in the Southern hemisphere below 45 degrees latitude, a pattern that contrasts with our observations from the Northern hemisphere. Only one specimen of the genus Chrysogorgia was ever identified in these southern waters, on the shelf of Antarctica. In particular, these corals were apparently never collected in the Drake Passage, despite numerous attempts to explore the deep benthic ecosystems of the area. While the Southern Ocean, and the Drake Passage in particular, may be a hospitable place of other coral groups, it seems bleak for the chrysogorgiids, who may not be able to survive there. <br />
<br />
Sampling in the deep sea is not a trivial task, and it may well be that chrysogorgiids are present in these southern waters, but, out of random chance or maladapted sampling strategies, were never collected. Chrysogorgiids, for instance, are often found on the hard substrates of slopes, canyons, and vertical wall, areas that are typically difficult to sample with traditional gear. During the Drake Passage Expedition, many different types of sampling gears are utilized, within a wide depth range, multiplying our chances to collect or observe chrysogorgiid corals. <br />
<br />
Unfortunately, after a week of work, and sampling at 20 stations, still no signs of chrysogorgiid corals. So what does it mean, if indeed these corals are so rare in these waters? Why would corals that are apparently able to grow and reproduce everywhere else in the world, would not be successful at colonizing the Drake? The absence of chrysogorgiids in this area has strong implications for the biogeography (past, current and future) of these animals. First, if waters South of the tip of South America are inhospitable, the Atlantic and Pacific coral fauna are expected to be strongly differentiated. Depending on how long ago these southern waters became inhospitable to chrysogorgiids, this dispersal barrier might have had a strong effect on the overall diversification history of these corals. The Drake shelters the typical habitats in which chrysogorgiids are usually found, so water chemistry characteristics might be the reason why these corals do not survive there. Understanding the link between coral geographic distributions and ocean chemistry may help us predict where corals lived in the past, and were they will be able to survive in the future. <br />

The geographic distribution of chrysogorgiid corals as we know it. Each location at which chrysogorgiids were sampled in marked as a blue dot. Gray dots are locations were over 16,000 octocorals (soft corals, sea fans and gorgonians) were collected, based on museum records, the taxonomic literature, and our own explorations of the deep sea (Pante, unpublished data, please do not use without permission). While chrysogorgiid corals are pan-distributed overall, they seem to be absent from the Drake Passage. Why is that?<br />

<br />
As we steam through day and night up to our elbows and knees in biological gunk, amazing sea life and fossil coral, we all look to the galley to keep up our energy. It is a magical wonderland of all things tasty. The galley is where the day starts and finishes. It is the one room without a monitor of the ships statistics and thus becomes the best friend of tea-breakers and a safe-haven for the overworked. The galley is so important that our body clocks are becoming acutely tuned to opening hours, reading: breakfast-like food break with cake, snack, cake with lunch, dinner and cake, snack (cake), midnight rations, cake, bed. <br />
<br />
As indicated above, the galley excels itself in the sweet treat department. Fresh cakes, bakes, biscuits seem to appear as if from nowhere at least twice daily. Once you step inside those four walls there is no escape, be it only for a simple cup of tea, you can guarantee leaving with a guilty look and a chocolate smear on your top lip which you are ‘just saving for later’ on questioning. It has now become standard practice to sneak from the lab, skulk down the hallway and into the galley to try and catch the cookies as they come freshly out of the oven. Here is a lost boy’s feast of toffee flans, pecan pies, macaroons, berry cheese cakes, peach surprise, ice cream cake, custard…..the list goes on. The fizzy drinks flow freely and most importantly for us Brits, so does the tea.<br />
<br />
A quirk of the shift system (12 hours on, 12 hours off) provides the perfect opportunity to guzzle anything on offer for whichever meal tickles one’s fancy. Most folk are so confused they don’t pay any attention to other people’s eating schedules, providing the perfect cover for feasting on chips and cake for breakfast, roast potatoes at every lunchtime, and pancakes with bacon and maple syrup for dinner. That child-like desire to do what shouldn’t be done takes over and all basic food rational fades into memories of a mystery world where the ground remained still, where trees grew and the sun shone…..and where there were no thruster engines to wake you up half way through your ‘off’ shift. Dieters beware, this is not place for the faint hearted…..I’m off for a cup of tea. <br />

<br />
Being out in the Southern Ocean on a ship has one thing in common with every other seagoing expedition: there is water all around us! It is the wonderful medium we are sailing on, but it is also the ‘air’ the corals breathe. Modern corals build their skeleton out of the ingredients they find in seawater today, and the fossil ones record the seawater chemistry of the past in their skeletons. <br />
<br />
In the global ocean each water mass has distinctive physical and chemical properties. If we can measure these properties precisely enough, we can distinguish the different water masses from each other. Here in the Drake Passage we have a set of water masses that play an important role when it comes to understanding the modern ocean circulation that transports heat and carbon around the globe. This pattern of ocean circulation has been different in the past, and it plays an important role in understanding climate change.<br />
<br />
But let’s get back to the water issue … In order to make meaningful interpretations of past water chemistry recorded in coral skeletons, we first need to get a good handle on the modern water chemistry. This is one of the reasons why we collect quite a bit of water on this cruise as well. We have two ways of doing so. The standard way of collecting water is to use the ship’s CTD. This is a big carousel with a central unit to measure conductivity, temperature, and depth (CTD), as well as oxygen content, and fluorescence. It has 24 bottles attached to it, which have lids at the top and the bottom that can be opened and closed remotely. All bottles are open when the CTD is lowered into the ocean, and we can ‘fire’ the bottles (close them) at any water depth we like on the way up. The second means we have to collect seawater is from similar bottles, attached to the towed camera system we use to take pictures of the seafloor. <br />
<br />
Once the water is onboard we take samples for a large array of chemical measurements ranging from dissolved carbon and other nutrient concentrations, to samples for isotopic measurements of various elements. The only measurement we do right here on the ship is to determine the alkalinity of the water samples. But this is a topic David Case, one of the graduate students on our expedition, will explain in more detail in one of the upcoming blogs.<br />
<br />
Today was a great day, as we got our second CTD. Today was also squish cup time! You have no clue what I am talking about? They are great souvenirs scientists like to produce during the process of water sampling, and here is how the story goes… What you need is a white cup made out of Styrofoam, a good selection of colorful sharpie pens, and some creativity. The decorated cup then goes into a meshed bag, which gets attached to the CTD, and descends to the deep ocean. As the pressure increases with water depth, all the air is squeezed out of the cup and it is shrunk to a much smaller size. It’s really a great souvenir to take home and you can see some examples in the pictures.<br />
