EK500 Water Column Sonar Data Collected During AL0110
NEFSC 2001 Fall Bottom Trawl Survey (AL0110, EK500). The NEFSC bottom trawl survey is a fisheries independent, multi-species survey that provides the primary scientific data for fisheries assessments in the U.S. mid-Atlantic and New England regions. Two bottom trawl surveys are conducted each year, one in the spring and one in the autumn. The survey is a standardized, stratified random design, with stratification based on bathymetry and multiple trawl sites within each stratum. Trawl sites are selected randomly, but the overall ship path is south to north. The survey covers the continental shelf and U.S. exclusive economic zone (EEZ) from Cape Hatteras, North Carolina into the Canadian EEZ. The primary gear is a bottom trawl, with CTD, multifrequency echosounder, and a host of other scientific sensor data collected ancillary to the bottom trawl catches.

Ecosystem Monitoring (AL0105, EK500). The Ecosystem Monitoring (aka Ecomon) survery uses bongo and CTD sampling to monitor and map the distribution of zooplankton, krill and smaller organisms) and the physical environment. The survey has been conducted four times per year (although fewer times in recent years) in each season on the continental shelf from Cape Hatteras, NC to the Canadian waters of New Brunswick and Nova Scotia. Acoustic data are occasionally collected. Marine mammal and bird observations have been collected in the past.

NEFSC 2002 Deepwater Biodiversity (AL0207, EK500). The primary objective is to collect fish, cephalopod, and crustacean specimens from the bottom and midwaters at maximum depths possible with available trawl wire. These collections will be used for tissue samples, photographs of freshly collected specimens and systematic characters, and voucher specimens in museum collections at the National Museum of Natural History, Peabody Museum, the Museum of Comparative Zoology, and the Delaware Museum of Natural History. These collections and observations contribute to ongoing research on biodiversity of deepwater nekton and other megafauna in the western North Atlantic. Additionally, the cruise will provide educational experience in deep-sea biology to students several institutions.
