    1. Sue,
      The recent storm has not really affected our data collection, although it may have affected some of the plankton that we collected. Rough weather may bring up more sargassum, which makes it more difficult to process the sample. I understand that stations may be skipped if the weather looks like it will be a problem.

  1. answer from Ms. Peters’s student:
    question #1: 170 feet long= about 51 meter.
    question # 2: 28 degrees Celsius=82.4 degrees Fahrenheit.
    question #3: Maybe the plankton could be preserved by putting it in the salted water at the same concentration of salt it uses to live.

    1. Nice job, Aya! You are correct in your answers to questions 1 and 2. Your prediction to question 3 is a good one, but we actually use ethanol (alcohol) or a salt water and formalin mixture. Both prevent decay of the animal tissues. See my most recent blog post for more information on that.

  2. Awesome descriptions of your first day! The photographs really help us understand the structure of the ship and all the safety features as well. I never knew about the origins of the word “knots”. I am learning so much already from reading your blog and it’s only Day 1!!

    1. Therese,
      The weather has been hot, but the breeze makes it pleasant. Once or twice the heat has gotten pretty intense while working on preparing the plankton samples. The ship has air conditioning, so when I’m inside I often have a sweatshirt on. The J frame is could be compared to an outrigger. The cables from the winches run through it to lower the CTD and the Bongo, and it can be maneuvered to lean out to the port side of the bow of the ship so that the CTD and Bongo are held away from the boat.

  3. Looks like fun! So now you know all about knots and how to measure the sea!
    Glad you’ve met some cool people! Hope your having fun! Looks like it! Also nice safety!
    See you soon

  4. Do you mind if I quote a couple of your posts as long as I provide credit and sources back to your weblog?
    My blog site is in the very same area of interest as yours and my
    users would truly benefit from some of the information you provide
    here. Please let me know if this ok with you. Cheers!
