Welcome to the data and mapping portal for the Gulf of Maine Census. Here, you can explore, download and map biological and physical data from multiple sources. The goal is to provide data that will enhance our understanding of biological patterns in the Gulf of Maine, across space and time.
The mission of the Gulf of Maine Biogeographic Information System (GMBIS) is to support regional needs for access to biological and biogeographical data from the Gulf of Maine area for research, public policy (management) and education. We provide two independent data download and mapping applications. Please explore both and let us know what you think. Enjoy!

Map the following biological datasets: National Marine Fisheries Service (NMFS) Northeast Fisheries Science Center (NEFSC) Bottom Trawl Survey, Clam and Quahog Survey, Herring Bottom Trawl Survey, Sea Scallop Survey, Shrimp Survey and the Maine - New Hampshire Inshore Groundfish Trawl Survey.
Map all sample locations, including those where selected species were not found.
Use a comma “,” in the Biogeographical Data Explorer and a plus sign “+” in the Biogeographical and Oceanic Data Integrator to search and map multiple species.
Search by taxa and filter (limit) the results within a time period and/or a physiographic region of the Gulf of Maine. Get more information on the physiographic regions
.
Download selected dataset as a comma-separated value (CSV) file.
The OBIS Schema is the content standard used by OBIS, the Ocean Biogeographic Information System; it is designed for marine biodiversity data.
Metadata records are available through the Global Change Master Directory (GCMD).
Physical data are available from the Gulf of Maine Ocean Observing System (GoMOOS) Ocean Circulation Model which is maintained by Huijie Xue and Fei Chai of the Ocean Modelling Group at the University of Maine Orono (UMO). It is based on the Princeton Ocean Model. Monthly averages of sea surface temperature, sea surface salinity, bottom temperature and bottom salinity can be mapped and downloaded.
Add WFS (Web Feature Services) layers to bring in data from Open Geospatial Consortium (OGC) compliant sources.
Integrate (append) physical oceanographic data to the selected biological data and download as one file.
Change the color of the selected species and turn multiple species on or off in the map.
Download data in a variety of formats including JPEG, PNG, SVG, KML/KMZ, GML, PDF, shapefiles and more.
Documentation and source code are open source and available to the community.
