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.

Distribution Formats
  • Kongsberg/Simrad instrument files (.raw or .wcd) (Version: 1)
    • File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.

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.
