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.
