Data Portal

This data portal provides users convenient access to digital marine boundary data distributed by various agencies. The marine boundary data portal will be updated as new data becomes available.

The data are organized by the following categories:

Core Marine Cadastral Data: Core marine cadastral data are comprised of U.S. maritime boundaries and limits, U.S. subsoil boundaries, and other U.S. marine boundaries. For descriptions of these boundaries, refer to U.S. Marine Cadastre.

Supporting Data: Supporting data have been identified as data needed to support alternative energy siting. Additional data will be added to this category as the project progresses.

If you would like for your data to become accessible through the marine boundary data portal, please contact the Marine Boundary Working Group at mbwg@csc.noaa.gov.
