OceanAdapt is a collaboration between the Pinsky Lab of Rutgers University, the National Marine Fisheries Service (NMFS), and Fisheries and Oceans Canada (DFO) 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 Canada, providing 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 DFO, 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.). 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 historical 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 (free reprint available from pinsky.marine.rutgers.edu/publications).
The projections of future species distributions were developed from statistical relationships between ocean temperature, bottom habitat features, and species abundance. Ocean temperature projections for the future were from global climate models developed for the Intergovernmental Panel on Climate Change. Full methods are described in Morley, J. W., R. L. Selden, R. J. Latour, T. L. Frölicher, R. J. Seagraves, and M. L. Pinsky. 2018. Projecting shifts in thermal habitat for 686 species on the North American continental shelf.

All of the data underlying these analyses are available for download, including spatially georeferenced catches from more than fifty thousand bottom trawl tows in six regions of the U.S and the Scotian Shelf region in Canada. Please notify us through the online form when you download the data, as this helps us justify maintaining the database as a community resource.
