Science Update - Incubation 1 & 2 Underway

    Yesterday, we collected seawater samples for Incubation 2. The weather continued to worsen during the day, so it was an all-hands operation to make sure that we could get the third cast done before the weather shut down the operation. This meant sending out a third cast while still filling bottles from the second cast. In the end, it all worked out and 40+ bottles were stored in the incubation van to begin Incubation 2. The science team modified the plan for Incubation 2 based on water samples from the area and the time remaining on the ship.

    Although we are on the RVIB Palmer until October 14th, we have to take into account the multiple day crossing of the Drake PassageStrait, connecting the Atlantic and Pacific oceans between Tierra del Fuego and the South Shetland Islands. Located about 100 mi (160 km) north of the Antarctic Peninsula, it is 600 mi (1,000 km) wide. and the day-long travel along the coast of Argentina and through the Straits of Magellan. This leaves us with about two more weeks of work days before experiments must be broken down and we begin to pack. In that time, we must finish Incubation 1 and 2 and set-up and run Incubation 3. There will also be samples to pack and label for immediate shipment to universities and research institutions. Other, smaller, experiments are also on-going and will need to wrap up in that time. We have weather and time to contend with as we make the final push to finish all of the planned science for this cruise, so we will take the opportunity to sample and filter every chance we get. Of course, we also need to eat. Our head cook, Michael Belloli fired up the grill and treated us to grilled chicken, steak, sausage, corn and other veggies. It was the perfect way to warm up after a long day in the cold trace metal van.

    Speaking of the Drake PassageStrait, connecting the Atlantic and Pacific oceans between Tierra del Fuego and the South Shetland Islands. Located about 100 mi (160 km) north of the Antarctic Peninsula, it is 600 mi (1,000 km) wide. - we are heading back to the deep water area later today to collect more seawater samples for the next series of experiments. We are hoping for a small weather window that will allow us to sneak out into the Drake, collect our samples, and then head back to the Peninsula to continue sampling along the Palmer LTER grid. Once the incubation sampling is complete this afternoon, we will secure everything and head back out to sea.

    Happy Birthday

    We just passed the halfway point of the research cruise. It feels like I have been on the ship for a while, but at the same time, it feels like we are just getting started. It is hard to explain. If there is one thing that is difficult about being at sea for long periods of time, it is the inability to easily communicate with friends and family. I am fortunate to have unlimited email capabilities from the ship and more Internet access than I expected upon my arrival, but it can still be difficult to not text, call or drive to someone's house whenever you want. So today, I am just going to dedicate this journal to the one person that I would like to be with today, my niece Ella. She is 13 today!

    Ella
    My beautiful niece, Ella, during a trip to Plymouth, MA this past summer.

    I am so overwhelmed by what a wonderful young lady she is and her amazing support of all the crazy adventures that I pursue. I wish that I could be with her, but instead, I will share with you the picture that she drew for me about two weeks before I left for this trip. She is incredibly skilled in drawing and other art projects and I knew she would make something great. She sat down on the couch and drew this without even looking at another image (as far as I know). She is a special lady, and today is all about her. I may be thousands of miles away, but I am thinking of her every second on her special day! HAPPY BIRTHDAY ELLA, I LOVE YOU!!!

    Emily - there are plenty of journals to look at to help answer this question. I recommend checking out the journal called: Nutrient
    Sampling, First Cast, Incubation Sampling Day 1, Fun with Filters and
    tomorrow's journal to find out more!

    Hi Aili - I am guessing that you mean how long does it take to sample the seawater? It depends on the depths needed for the samples and the
    number of bottles on the rosette. Deep casts can take a few hours.
    Shallow casts usually take 15-20 minutes, followed by an hour to and
    hour and a half to distribute the water and move the bottles to
    incubation.

    Hi Kyle - once we are done with water samples from an incubation or station sample, the bottles are rinsed and prepared for the next
    sampling event.

    Alanna - the research is still underway, so we don't have any final analyses yet. It will take some time after the research cruise to
    analyze samples, so it will be a while before publications are produced

    Hi Michael - I do mean that the experiments will end and the bottles will be emptied. In cases where additional nutrients have been added,
    the seawater cannot be placed back into the ocean. The water is treated
    as waste and disposed of properly as chemical waste.

    Mia - take a look at some of the other journals, specifically Incubation Prep, Incubation Sampling Day I, First Cast, Diatoms and Iron
    Hypothesis to find out more about the experiment. Sea water samples can
    be taken at any depth. In order to sample for diatoms, water is
    collected above about 150m/450ft in the photic (light) zone.

    Robert - Everything about Antarctica is cool! I am enjoying my experience and looking forward to the second half of the cruise!

    The diatoms live in the seawater, so in order to get diatoms, we must collect seawater. The science team is taking advantage of every day
    that we have at sea. We usually sample water (weather permitting)
    everyday - sometimes more than once per day. In fact, today, we will
    collect sea water on at least 6 different casts.

    In a number of my journals I have discussed how weather has kept us from sampling. The wind can make deployment unsafe for crew or the
    equipment. In this area, high winds are likely, so there can be times
    when operations are not possible because of weather.

    Hi Toto! Thank you very much for the birthday shout out! I had a very good birthday and it was nice talking to you! 8 just learned this is how to comment on your journals so now I will comment on them if I have questions, hope you are having an awesome trip! I love you

    Cara Pekarcik

    Hi Morgan - be sure to take a look at some of the other journals to find out more about the samples that are collected. In general, we use
    the term seawater, but the water contains elements and microorganisms
    that the science team intends to study. This particular research cruise
    is not focused on larger organisms. BTW - corals are generally found in
    warmer, clear waters.

    Hi Mrs. Pekarcik! Are the samples going to be picked up by the research institutes or is the research team going to bring the samples to them after you return?

    Cara Pekarcik

    The science team has included money in their research cruise budget for shipment of samples. The samples will be shipped ASAP from the ship
    once we arrive in port. The samples will go to the three universities
    (URI, ODU, & USF) that are collaborating on this study along with the
    Woods Hole Oceanographic Institution where Dr. Randie Bundy is working
    on her post-doctorate research.

    How is the water collected into the bottles, why do you need so much, and how large is the volume of each bottle?

    Cara Pekarcik

    Hi Jason - check out the journals titled First Cast or CTD to find out more about the equipment used to collect the water. Nisken bottles can
    vary in size. We have bottles that hold between 10-15L of seawater.
    Large quantities of water are needed to fill all of the incubation
    bottles and to filter enough water to collect diatoms for study.

    Nha H, Block A

    About how long did it take for you to fill up 40+ bottles? Was it a difficult task?

    Andrew Tobin

    On board the ship, did you take just us much food needed for the voyage or did you bring a surplus of ration in case of unforeseen complications?

    Cara Pekarcik

    There is plenty of food ordered prior to this cruise. The cooking staff create 'shopping lists' based on the number of people on the
    research cruises and the number of days for the cruise. It is always
    possible to run out of certain items, but there is still plenty of food
    left on the ship with two weeks to go.

    Hi Nha - if you look back on the first Incubation Sampling Day 1 journal, I mentioned that filling 60+ bottles took about 11 hours. This
    includes the time of the CTD casts and preparing the bottles for the
    incubator. The 40 bottles took less time because there were fewer
    bottles and because we had a system in place to make the task efficient.

    What experiment are you going to do with the seawater samples?

    Tyla P, Block E

    How many seawater samples do you need?

    Cara Pekarcik

    Hi Maritza - take a look back at the journals about incubation sampling and you will find out more about the experiments. They are largely
    based on levels of iron, but other samples are taken as well.

    The most exciting part is the location! We always have beautiful scenery or the ocean to look at during the sampling. As for the
    incubation sampling, everyone is busy inside their own labs.
