Count Component Title Abstract
1 EK500 Water Column Sonar Data Collected During AL0002 NEFSC 2000 Spring Bottom Trawl Survey (AL0002, EK500). The objectives of the cruise are to: (1) determine the spring distribution and relative abundance of fish and selected invertebrate species; (2) collect biological samples for studies of age and growth relationships, fecundity, maturity and food habits; (3) collect hydrographic and meteorological data; (4) collect samples of ichthyoplankton and zooplankton; and (5) make data and sample collections for cooperative researchers and programs; (6) conduct a hydroacoustic survey between survey stations.

            1 Albatross IV (AL) Albatross IV (AL) The NOAA Ship Albatross IV conducted fishery and living marine resource research in support of NOAA's National Marine Fisheries Service (NMFS), Northeast Fisheries Science Center's (NEFSC), Woods Hole Laboratory in Woods Hole, Massachusetts. The ship's normal operating area was the Gulf of Maine, Georges Bank, and the continental shelf and slope from Southern New England to Cape Hatteras, North Carolina. Typical assessment work included groundfish surveys and Ecosystem Monitoring surveys. Research conducted from the Albatross IV provides an understanding of the physical and biological processes that control year class strength of key economical fish, shellfish and zooplankton species. The vessel was operated by NOAA's Office of Marine and Aviation Operations. The Albatross IV was decommissioned on 20 November 2008.
