Count Component Title Abstract
1 EK60 Water Column Sonar Data Collected During DE0910 NEFSC 2009 Atlantic Herring Acoustic/Midwater Trawl Survey (DE0910, EK500). The NEFSC Atlantic herring acoustic survey is a fisheries independent survey that provides scientific data for Atlantic herring assessments in the U.S. mid-Atlantic and New England regions. The survey is conducted in the fall on pre-spawning and spawning herring primarily in the Georges Bank region, but with other historical sites in the Gulf of Maine surveyed. The survey is a systematic design with parallel transects oriented perpendicular to bathymetric features. Midwater trawl sites are selected on an ad hoc basis to sample acoustic backscatter attributed to Atlantic herring as well as backscatter by other organisms. The primary gear is multifrequency Simrad echosounders, but midwater trawl, CTD, and a host of other scientific sensor data are collected ancillary to the acoustic data.

            1 Delaware II Delaware II (DE) The NOAA Ship DELAWARE II conducts 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, MA. The ship's normal operating area is the Gulf of Maine, Georges Bank, and the continental shelf and slope from Southern New England to Cape Hatteras, NC. Typical assessment work includes groundfish assessment surveys and Marine Resources Monitoring, Assessment and Prediction (MARMAP) surveys. Research conducted from the DELAWARE II provides an understanding of the physical and biological processes that control year-class strength of key economical fish species. The vessel is operated by NOAA Marine and Aviation Operations.
