2009 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake (Merluccius productus) (MF0903, EK60)

Metadata Updated: February 7, 2018

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 2009 Integrated Acoustic Survey (IAT) survey aboard the NOAA Ship Miller Freeman and the Canadian Coast Guard Ship (CCGS) W.E. Ricker, both are stern trawlers 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 on Miller Freeman (US portion) began from north of Point Piedras Blancas, CA (35.8?N) to the northwest tip of Washington state (48.4?N) between June 30 and Aug. 22, while the survey on W.E. Ricker began from near US/Canada border (48.55?N) to the Dixon Entrance area, Canada (54.9?N) between Aug. 13 to Sep. 7. 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. However, this package includes only the EK60 raw data from the US portion only.
