Count Component Title Abstract
1 EK60 Water Column Sonar Data Collected During HB1002 NEFSC 2010 Spring Bottom Trawl Survey (HB1002, EK60). 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.

              1 Henry B. Bigelow (HB) Henry Bigelow (HB) NOAA Ship Henry B. Bigelow is one of the most technologically advanced fisheries survey vessels in the world and it supports NOAA's mission to protect, restore and manage the use of living marine, coastal, and ocean resources through ecosystem-based management. Its primary objective is to study and monitor Northeast Marine Fisheries, throughout New England. The ship also observes weather, sea state, and other environmental conditions, conducts habitat assessments, and surveys marine mammal and marine bird populations.
