EK60 Water Column Sonar Data Collected During SE1102L2

TZCF Oceanographic Survey (SE1102L2, EK60). Data were collected along the 158°W and 161°W Meridionals from 22°30′N-36°00′N and from 31°15′N-35°15′N. 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 and currents were monitored using the EK60 echosounder system (38, 70, and 120 kHz) and an RD Instruments ADCP along the transects.

    AWS Cloud Storage provides additional public access to water column sonar data through the NOAA Big Data Project
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 properties of major fronts within the North Pacific Subtropical Frontal Zone, where cooler, more productive subarctic water meets and sinks under warmer, less productive, subtropical water. This highly dynamic region influences the distribution of top predators’ (such as tuna, swardfish) and turtles, resulting in changes in CPUE of fish and rates of fisheries interactions with turtles.
    Use Limitations
    • These data are considered raw and have not been subjected to the NOAA's quality control or quality assurance procedures. They are released for limited public use as preliminary data to be used only with appropriate caution. NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system.
