For Ms. Garrison’s class who are studying weather, here is a photo of the anemometer on the bow of the ship.

    I believe the small, white bee-hive looking instrument next to the mast is a temperature sensor. I’m not sure what the instrument is just to the right of the anemometer.

    My second graders had some more questions for you:
    We are studying the dragonfly nymphs in our pond and so one of the students asked, “Do people ever sea dragonfies out at sea?”

    Another child asked, “How old is the youngest person to go down in one of the research subs?”

    Another child wanted to know, “How cold is the water at the bottom of the ocean where you are working?”

    All pretty good questions, huh?

      Thanks for your questions Ms. Garrison’s class!

      We do occasionally see insects out at sea. They can be swept out here by storms and are eaten by the birds and fish if they fall into the water. We have also seen large Green Darner Dragonflies during our fall cruises further south. They appear to be migrating but we would need to do more research to be certain about what they are doing.

      We are still talking about who is the youngest person to go in a research submersible. We believe it was probably someone who was in college, which would mean somewhere around 20, but we are not certain yet. On this mission we are using JASON, an ROV, (remotely operated vehicle) which means that no one is inside of it. It is steered from the ship, sort of the way a remotely controlled toy car or airplane might be, just much more complicated. In talking with the ROV crew they think the youngest JASON pilot was 24 when he first started.

      I am glad you are interested in the temperature at the bottom “where you are working.” As you probably know, the temperature varies depending upon where you are. We use a CTD (you can read about it on the blog) to measure the temperature. Many of our bottom readings come back around 6 C (or 42 F) which is cold!

      Please send us additional questions, and let us know what you think our Chief Bosun, Bruce, should draw on a styrofoam wig head that we will send down on the JASON.
