Science Log

If you have been using the ship tracker you would be able to follow that last night we cruised around the bottom tip of Florida out of the Gulf of Mexico into the Atlantic Ocean. The waters were a bit rough with wind gusts up to 40 knots. It was a rocky night. Not to mention a very sleepless night with the greenish way I was feeling :)! Needless to say I haven’t had much to eat today except for some dry Captain Crunch cereal. The head chef on the mess deck suggested it would be a good stomach filler. We will see and I will let you know!

Once I got my sea legs back I was anxious to see what everyone else was doing. The crew as well as the scientists were very busy; therefore, I stayed pretty much out of their way for a while. The crew was trying to get us an arrival in Jacksonville, FL and the tech crew was busy trying to get us online since the internet signal went down. Talking to the captain he says that with a new boat there are always kinks that have to be ironed out …that’s why we call these sea trials.

The mammal scientists were working on their equipment trying to get their equipment calibrated correctly. They explained to me that PISCES is equiped with many sensors (transducers) and these sensors are connected to different pieces of equipment to help pickup the ocean ecosystem. For instance, the mammal scientists are using the echo sensors on the computers (see below) that operates seven echo sound frequencies. Then the scientists can use this realtime data for analysis of targets, concentrations, the layers of ocean, etc. This provides a broad scope of marine acoustic survey from plankton to large schools of fish.

While I was on deck watching the waves I noticed a bunch of birds that flew into the water but never came up. I watched a while longer and again, but this time these creatures came up from the water and flew across it into a huge dive back into the ocean. These were not birds…..these were ‘flying fish’! They are C.melanurus common to the Atlantic. They are silly little fish always flying from a predator under water.
