Oceanographic Survey in the American Samoa Exclusive Economic Zone (EEZ) (OES0403, EK60)
Oceanographic data were collected along predetermined transects in the American Samoa EEZ. CTD cats were conducted at predetermined stations. CTDs were equipped with oxygen sensors and fluorometers, and chlorophyll and nutrients were measured at discrete depths. Biological backscatter were monitored using the EK60 echosounder system (38, & 120 kHz) along the transects. Currents were continuously recorded using an RD Instruments Acoustic Doppler Current Profiler (ADCP).
