EK80 Water Column Sonar Data Collected During HB2401

Data provided by  National Oceanic and Atmospheric Administration

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.

EK80 Water Column Sonar Data Collected During HB2402

Data provided by  National Oceanic and Atmospheric Administration

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.

EK80 Water Column Sonar Data Collected During HB2404

Data provided by  National Oceanic and Atmospheric Administration

A long-range autonomous underwater vehicle (LRAUV) was tested for collecting underwater stereo imagery of the seabed and biology on the seabed. The immediate use of the LRAUV is to supplement the scallop survey, which is currently done using the towed system, Habcam. In addition to LRAUV evaluation, we tested and evaluated the newly-installed Kongsberg EK80 systems. We tested continuous wave (CW) and frequency modulated (FM) signals, data acquistion rates, and calibrated the systems in CW and FM modes.

EK80 Water Column Sonar Data Collected During HB2405

Data provided by  National Oceanic and Atmospheric Administration

The cruise will survey and collect samples of deep-sea corals and related marine life in the canyons in the northern Gulf of Maine in U.S. and Canadian waters. The U.S. and Canadian scientists (National Systematics Laboratory at NOAA’s Northeast Fisheries Science Center; Dalhousie University in Halifax, Nova Scotia) will work aboard the NOAA Ship Henry B. Bigelow. They will use a remotedly operated vehicle (ROV) owned by Canada.

EK80 Water Column Sonar Data Collected During RL2107

Data provided by  National Oceanic and Atmospheric Administration

The survey domain, from Cape Flattery, WA to Central Baja California, Mexico, was defined primarily by the modeled distribution of potential habitat for the northern subpopulation (stock) of Pacific Sardine (Zwolinski et al., 2011), with a southern extension permitted by available sampling effort.
