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).

Purpose | The scientific objectives of this cruise are to collect data on physical and biological oceanographic properties of the American Samoa EEZ where dynamic eddy activity is created by the interactions of the eastward flowing South Equatorial Counter Current and the westward flowing South Equatorial Current. Mesoscale eddy activity varies at different temporal scales and seems to affect catch rates of the albacore in the region. |
