The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted an acoustic-trawl (AT) stock assessment survey in the Gulf of Alaska during late spring/early summer of 2003 to estimate the distribution and abundance of walleye pollock (Theragra chalcogramma). The survey was conducted along the Gulf of Alaska (GOA) shelf and shelfbreak from the Shumagin Islands to Prince William Sound, 4 June to 16 July 2003, aboard NOAA Ship Miller Freeman, a 66 meter stern trawler equipped with acoustic and oceanographic instrumentation. The vessel departed Kodiak, Alaska on 4 June and arrived in Kodiak on 16 July. The echosounder system was calibrated at the start of the cruise in Three Saints Bay, Kodiak Island, Alaska on 5 June, and at the end of the cruise in Ugak Bay, Kodiak Island, Alaska, 16 July 2003.

The transducers installed on the Miller Freeman were mounted on a deployable centerboard. The transducer draft settings are nominally correct when the centerboard is fully extended (draft correction setting is 9.15 meters below the surface). When the centerboard is in the retracted position (transducers approximately flush with the vessel's keel), the transducers are nominally 6.15 meters below the surface. The echosounder system was calibrated at the start of the cruise in Three Saints Bay, Kodiak Island, Alaska 6 June 2003, and at the end of the cruise, 16 July 2003 in Ugak Bay, Kodiak Island, Alaska.

This echo sounder was widely used by NOAA Marine fisheries researchers until its replacement by the Simrad EK60 echo sounder MF0309_EK500 completed NOAA Ship 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.

The new electronic hardware is combined with up to date PC processing and Windows operation. The EK60 provides facilities for accurate echo sounding, data storage, data analysis and reporting results. The system communication is through Ethernet, which gives flexibility in the location of the EK60 system units and allows easy access to data from other instruments or stations on a vessel network. A post processing software, BI60, is also included in the EK60 system.
