The Northeast Fisheries Science Center (NEFSC) has conducted resource cruises out of Woods Hole, Massachusetts, since 1885. Our scientists research marine mammals, groundfishes of the Atlantic, and their habitats. Standard bottom trawl surveys were initiated in the fall of 1963, and since 1968 have been completed each spring and fall. Cruises to monitor shellfish resources have been conducted since the late 1970s, primarily for sea scallops, surf clams and ocean quahogs. On all cruises, oceanographic, as well as meteorological data are collected. The data obtained from the standard trawl surveys are universally recognized as the most scientifically valuable time series of fisheries related data in the world.
