The Outer Continental Shelf (OCS) is the portion of the internationally recognized continental shelf that is under federal jurisdiction of the United States, between the boundaries of the states' jurisdiction and international waters. The term "outer continental shelf" refers to all submerged lands, its subsoil, and seabed that belong to the United States and are lying seaward and outside of the states' jurisdiction. The United States OCS has been divided into four leasing regions: Gulf of Mexico OCS Region, Atlantic OCS Region, Pacific OCS Region, and Alaska OCS Region. These lands were managed by BLM until BLM transferred its responsibilities for the OCS to the Minerals Management Service (MMS) in 1982. Most publications are Planning/NEPA reports along with a few research reports.
