The above picture shows the SeaHorse being deployed for the process study near Ross Bank in Antarctica a few days ago. The buoy was then recovered five days later. The buoy has a set of sensors attached to it which measure a whole suite of environmental variables (temperature, salinity, oxygen, fluorescence, etc.). Upon recovery the data are analyzed onboard of NBP.
