ME70 Water Column Sonar Data Collected During SH1103
The 2011 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake (Merluccius productus) (SH1103, ME70). 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 2011 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 near Morro Bay, CA (35.2°N) to the west of Barkley Sound, Canada (51.7°N) between June 23 and Sep. 5, while the survey on W.E. Ricker began from near US/Canada border (49.2°N) to the Dixon Entrance area, Canada (54.9°N) between Aug. 13 to Sep. 9. 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.
