| Description |
During the months of August-October, 1998, the National Marine Fisheries Service and the New England scallop industry conducted a cooperative survey of Closed Area II to assess the sea scallop population after 3.5 years of closure to all fishing. The area was closed in December 1994 to conserve fish stocks. Most of the tows are concentrated in the southern part of Closed Area II (south of 41o 30'N) and in the northernmost part (north of 41d 50'N). The central area between 41d 30' and 41d 50'N was sparsely sampled. See the location map (1998lm.pdf) for the 1998 survey. The survey results were used here to plot species distribution maps. For the species abundance maps, the data includes all tows of 9, 10 and 11 minutes duration (895 tows; ca21998srvabundA.pdf and ca21998srvabundB.txt) and excludes all replicate tows at sites where repeated tows were conducted in depletion experiments. For the species presence/absence maps, the data includes all tows (1544; ca21998srvpresabA.pdf and ca21998srvpresabB.txt ) except for those with bad navigation. [More]
