Williamson, and T. Honkalehto. 2007. Results of the echo integration-trawl survey of walleye pollock (Theragra chalcogramma) on the Bering Sea shelf in June and July 2006. AFSC Processed Rep. 2007-08, 40 p. Alaska Fish. Sci. Cent., NOAA, Natl. Mar, Fish. Serv., 7600 Sand Point Way NE, Seattle WA 98115. Scientists from the Alaska Fisheries Science Center’s (AFSC) Midwater Assessment and Conservation Engineering (MACE) Program conduct biennial echo integration-trawl (EIT) surveys (e.g., Honkalehto et al., 2002) along the eastern Bering Sea shelf during the summer to estimate the abundance and distribution of walleye pollock (Theragra chalcogramma). This report summarizes observed walleye pollock distribution, and provides walleye pollock biomass and abundance estimates by size and age for the EIT survey conducted in June-July 2006 within the U.S. Exclusive Economic Zone (EEZ). An inter-vessel acoustic comparison between the NOAA ships Miller Freeman and Oscar Dyson was also conducted during the cruise and results will be presented elsewhere (De Robertis et al., in press). completed Honkalehto, Taina taina.honkalehto@noaa.gov pointOfContact Towler, Rick rick.towler@noaa.gov custodian asNeeded DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Acoustic measurements were collected from 16 m below the sea surface to within 0.5 m of the sounder-detected bottom or a maximum of 1,000 m in deep water. Data were analyzed using Myriax Echoview post-processing software. See National Marine Fisheries Service (NMFS) 2013.
