Palmer (NBP) in March/April 2009 on the Southern Ocean. It shows how we collect water with the CTD (Conductivity, Temperature, Depth) Rosette, and a few experiments that the water goes through after it is collected. First we show filtering for chlorophyll content in phytoplankton, then the incubation of the samples used to study the primary productivity of phytoplankton, and lastly, the culture experiments that went on for as long as 16 days to study the effect of Iron addition on phytoplankton.
