(Left) Research assistant Linda Nguyen attaches an acoustic Doppler current profiler (ADCP) to the CTD (conductivity, temperature, and depth). This ADCP will be used to collect acoustic backscatter data on the small organisms in the water column. (Right) The CTD is recovered using Research Vessel Robertson’s winch system as curious black-footed albatrosses watch from the water.
