It’s hard to believe that we set sail just yesterday from our anchorage at Francis Bay, St. John. So much science has happened since! When we were leaving St. John, we took three surface samples to get an idea of how nutrients and chlorophyll change from inshore to offshore, stay tuned for those exciting discoveries. B-watch completed a neuston tow last night where they caught lots of zooplankton and Sargassum. Very early this morning, A-watch completed a 100-count of the zooplankton where we found tons of amphipods and isopods (see image). We also identified three different types of Sargassum. I have yet to try the famed Sargassum tea, but I have high hopes.
C-watch is currently working on their first science superstation. We have our stays’ls aback, and we are trying to move as little as possible because there will be sampling gear in the water. C-watch will listen and record the underwater seascape sounds using a hydrophone with Sarah Weiss, a wonderful whale specialist joining us from NOAA. They will also use the hydrowire to deploy some exciting equipment, including a secchi disk, which is a white plastic disk that we use to determine how far light penetrates through the ocean. Next they will deploy the carousel to see how different oceanographic parameters change with depth. And lastly, they will complete another neuston tow, which means more 100-count fun!
We had our first taste of downwind sailing yesterday and that in conjunction with mild winds has kept everyone feeling good. Here’s to more of that! Shout out to the galley for making some incredible cinnamon rolls for breakfast <3
P.S. Happy birthday dad!! Sending all my love from the high seas. xo
