Bigelow during pelagic, bottom-trawl, and marine mammal surveys. Acoustic sampling operations include continuous measurements using hull-mounted transducers and multi-frequency scientific echosounders. Biological sampling with midwater and bottom trawls, and underwater video deployments is conducted to verify species-specific backscatter and characterize sea-floor habitat. In-situ and laboratory experiments aid in understanding species-specific acoustic measurements. We are continuously developing, testing, and evaluating advanced sampling technologies during laboratory and field experiments to improve abundance estimates and map spatial and temporal distributions of fish and invertebrates. Acoustic, optic, and biological data are audited and archived in the NEFSC relational data management system. The Fisheries Acoustic Research Program Advanced Sampling Technologies Research Group (ASTRG) implements state-of-the-art fisheries acoustic technologies to provide cost-effective and accurate fisheries-independent population estimates of commercially important pelagic fish stocks in the Northwest Atlantic.
