The 2003 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake (Merluccius productus) (MF0316, EK500)

Scientists from the Fishery Resource Analysis and Monitoring (FRAM) division at the NOAA Fisheries Northwest Fisheries Science Center (NWFSC) and the Pacific region of the Department of Fisheries and Oceans Canada (DFO) conducted the Joint 2003 Integrated Acoustic Survey (IAT) survey aboard the Canadian Coast Guard Ship (CCGS) W.E. Ricker, a stern trawler equipped for fisheries and oceanographic research. Pacific Hake (Merluccius productus) aggregations were targeted along the continental shelf and upper slope of the entire survey area.

Hake populations were surveyed along a series of parallel line transects that in general were oriented east-west, spaced at an interval of 10 nmi apart, and traversed sequentially in alternating directions; The survey began from south of Monterey, CA (36.1°N) to the Dixon Entrance area, Canada (51.4°N) between June 29 and Sep. 1. All transects up to the Dixon Entrance and along the west coast of Haida Gwaii were completed. Sea depth at the inshore end of individual transects was nominally 50 m. Offshore extent of individual transects was typically at a depth of 1,500 m.

Distribution Formats
  • Simrad EK500 data logged in .ek5 format (Version: 1)
    • File Specification: Simrad EK500 data logged With Echolog 500. These files contain EK500 data telegrams output by an Ex500 on its Ethernet port. The .ek5 file contains binary Ethernet packets as output by the Simrad echosounder. The EK500 manual contains full details of the EK500 Ethernet telegram formats and should be consulted for interpreting the Ethernet packets recorded within an .ek5 file.
