Science and Technology Log
Most of this watch will be spent steaming to the first southern station. Our ETA (estimated time of arrival) is 8:00 am. We are planning to do a full station meaning CTD, Neuston, and a Trawl. It is midnight now and I am hoping to get an interview with our Chief Scientist prior to beginning the station.
The first Bongo is scheduled for noon. Dan Carlson, a graduate student at Florida State University, is aboard researching his master’s thesis. He is utilizing the water samples from the Bongo to learn more about the development and origination of red tides which bloom in the Gulf of Mexico.
I have just been put “in charge” of the Neuston for this station. That means I am responsible for seeing that the net is dragged for ten minutes, that the organisms which are gathered are washed down into the cod end and that the sample is then gathered are delivered to the plankton transfer table.
The Chief Scientist has been actively engaged with data collection and correction activities. I understand that a server has failed and that all time/date information must be hand entered into all data sheets. This is time consuming but very necessary for the sake of accuracy.
Question of the Day
What is red tide?
Answer: It is an organism, named Karenia Brevis, which produces a neurotoxin which, in turn, is toxic to virtually all sea life.
