OceanAdapt is a collaboration between the Pinsky Lab of Rutgers University and the National Marine Fisheries Service (NMFS) to provide information about the impacts of changing climate and other factors on the distribution of marine life to the National Climate Assessment, fisheries communities, policymakers, and to others. This website hosts an annually updated database of scientific surveys in the United States and provides tools for exploring changes in marine fish and invertebrate distributions. We are continually working to expand the site with new data and visualization tools.
The distributions of fish and invertebrate populations are routinely monitored by NMFS and other agencies during bottom trawl surveys on the continental shelves of North America. These surveys provide core information for use in fisheries management and extend back two to five decades. For the indicators displayed on this website, a mean location (the centroid) is calculated for each species in each year of each survey, after the surveys have been standardized to a consistent spatial footprint through time. The centroid is the mean latitude and mean depth of catch in the survey, weighted by biomass. For the regional and national indices, the first year is standardized to a value of zero and changes are then averaged across species in a region. Only regions with consistent survey methods and without coastlines that would prevent poleward shifts in distribution are included in the national average (currently Eastern Bering Sea and Northeast U.S. Spring). Only species caught every year are analyzed to prevent changes in species composition from affecting the indicator. The indicator begins in the first year that data are available from the focal regions.
The basic analyses and data are described in Pinsky, M. L., B. Worm, M. J. Fogarty, J. L. Sarmiento, and S. A. Levin. 2013. Marine taxa track local climate velocities. Science 341: 1239-1242 doi: 10.1126/science.1239352
