Count Component Title Abstract
1 EK60 Water Column Sonar Data Collected During MF0509 2005 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake (Merluccius productus) (MF0509, EK60). 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.

            1 Miller Freeman Miller Freeman (MF) The Miller Freeman was decommissioned on 3/29/13 after many years of exemplary service. Pictures of the ceremony will be posted here when available - please check back soon. Miller Freeman was a 215-foot fisheries and oceanographic research vessel and was one of the largest research trawlers in the United States. Miller Freeman's primary mission was to provide a working platform for the study of the ocean's living resources. The ship was named for Miller Freeman (1875-1955), a publisher who was actively involved in the international management of fish harvests. The ship was launched in 1967, but not fully rigged until 1975. The vessel was again re-rigged in 1982. Miller Freeman was homeported at the Marine Operations Center-Pacific in Newport, Oregon. With a 12,578 mile / 31 day endurance, Miller Freeman was capable of operating in any waters of the world. Miller Freeman was owned by the United States of America, Department of Commerce's National Oceanic and Atmospheric Administration. The ship was operated by NOAA Marine and Aviation Operations and carried a complement of 7 NOAA Corps officers, 27 crew members, and maximum of 11 scientists.
