This morning C-watch was woken bright and early for morning watch. Some tasty breakfast burritos brightened our morning as we prepared for an eventful watch. Sails were set and struck, morning chores completed, hourly boat checks and weather observations conducted, and a lucky few learned how to use a sextant for the first time. Even in the increasingly large swells, things carried on as usual in Science World. Every day at noon and midnight (weather and sea state permitting) we 'park' the ship under sail for science, and the Hydrocast and Neuston Net are deployed over the side. The Hydrocast is programmed to collect water samples at different depths, which are later processed to find pH, Alkalinity, chlorophyll content, microplastics, etc of different depths in the water column. The Neuston Net is dragged along the surface to collect any Sargassum seaweed, zooplankton, microplastics, and other organisms living near the surface, which is hand sorted and processed later. Last night we picked 148 tiny pieces of plastic out of our Neuston tow. Yikes! The watch schedule is constructed so there are always people looking after the ship, and always people in the lab, day and night. That means round the clock science! And round the clock dish duty...
Afternoon class was devoted to working on our research projects. On shore we broke into pairs to design an oceanography research project. Before boarding, each pair turned in their research proposal, to be carried out on the ship. Areas of study include phytoplankton vertical migration, ocean acidification, bioluminescence, Sargassum shrimp, ocean currents, microplastics, and Halobates (the ocean version of water striders). Today we were paired up with the assistant scientists to figure out how the practical side our projects are really going to work out at sea. It never stops to amaze me how much science can be done in such a small, constantly moving lab, in the middle of the ocean.
Well, hopefully this was a fun post for the science nerds out there, and for those of you out there yawning into your screens, I'm sure you'll have better luck next time. That's all for now!
