Submarine Cable Areas - U.S. and Affiliated Territories

Published by Pacific Islands Ocean Observing System (PacIOOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 21, 2026 at 12:18 PM | Dataset Last Updated: January 27, 2023 at 12:00 AM
These data show the general location of commercial and research submarine cables within U.S. waters. The majority of these cables are for telecommunications, and the remaining are for power transmission. The geographic footprint for each cable may vary and is dependent on the original source data. In the nearshore, cables are routinely buried below the seabed. In the offshore, they are placed directly on the seabed. A submarine cable area may contain one or more physical cables. 30 CFR 585.301 defines a minimum 100-foot-wide right of way grant on each side of a cable.
