Oceanographic Survey in waters of the Northern Mariana Islands, Guam, and Micronesia (SE1003, EK60)
The goals of the cruise were to collect acoustic backscatter and oceanographic data
at the vicinity of CNMI, Guam, and in the northern part of Micronesia. Data collected
consisted of CTD casts, trawl samples, and continuous monitoring of currents and biological
acoustic backscatter. CTD cats were conducted at predetermined stations. CTDs were
equipped with oxygen sensors and fluorometers, and water was sampled at discrete depths
during each cast for nutrients and chloropigment determinations. Trawl operations
were conducted at predetermined stations using an Isaacs Kidd midwater trawl at depths
of the shallow sound scattering layer. Currents were continuously monitored using
an RD Instruments Acoustic Doppler Current Profiler (ADCP) operating at 75 kHz frequency.
Biological backscatter was recorded using an EK60 echosounder system along predetermined
transects, operating at 38, 70, & 120 kHz frequencies.

Purpose | The scientific objectives of this cruise are to collect data on physical and biological oceanographic properties of CNMI, Guam, and northern Micronesia. The region surveyed is located in the path of the North Equatorial Current and near the North Equatorial Counter Current. Possible effects of these currents and their interactions of island topography are investigated. |
