The Naval Seafloor Cable Protection Office provides the single point of contact and management of a world-wide Geographic Information System (GIS) database of commercial and Government submarine cable systems. The NSCPO is uniquely positioned to respond to queries from commercial and Government cable owners, planners, surveyors and installation contractors in order to minimize possible damage to DoD cable systems and other seafloor assets. These inquiries are managed in a comprehensive tracking database. Additionally, the NSCPO maintains a large array of supporting datasets that include world-wide bathymetry, geological, geotechnical, petroleum, Marine Protected Areas, maritime boundaries and digital charts.
In order to ensure that new commercial or Government cable projects are routed clear of any DoD cable systems, the NSCPO requests system planners and installation contractors to contact NSCPO early in the planning process. All data provided to the NSCPO will be treated as commercially proprietary.

Joint BOEM and NOAA Marine Information System – Marine Cadastre
MarineCadastre.gov is a marine information system jointly maintained by NOAA’s Office for Coastal Management and the Bureau of Ocean Energy Management (BOEM) that provides maps, data, and tools related to offshore energy and marine planning.
MarineCadastre.gov was initiated under Section 388 of the Energy Policy Act of 2005 which directed the Department of the Interior, in coordination with the U.S. Department of Commerce, U.S. Coast Guard, and U.S. Department of Defense, to establish an interagency comprehensive digital mapping initiative for the Outer Continental Shelf to assist in decisionmaking relating to the siting of activities covered under subsection (p) of section 8 of the Outer Continental Shelf Lands Act (43 U.S.C. § 1337) (as amended).
Maps, data, and other information are accessible at MarineCadastre.gov.
The NASCA Member Submarine Cable System Maps display the cable routes of entities that are members of the North American Submarine Cable Association (NASCA).
