Project aboard

We will deploy profiling packages, scientific echosounders, plankton nets, and will collect water from the CTD rosette Niskin bottles for on-deck incubation, and analysis both on board and for shipping back to our labs. Profiling and sampling will occur around-the-clock, but with emphasis on dawn and dusk.
