EK500 Water Column Sonar Data Collected During MF0509
The 2005 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake (Merluccius
productus) (MF0509, 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 2005 Integrated Acoustic Survey (IAT) survey aboard the NOAA Ship Miller
Freeman, 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 north of Point Piedras Blancas, CA (35.7°N) to the Dixon Entrance area, Canada (54.5°N) between June 20 and Aug. 19. 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.
