All submerged lands seaward and outside the area of lands beneath navigable waters. Lands beneath navigable waters are interpreted as extending from the coastline three nautical miles into the Atlantic Ocean, the Pacific Ocean, the Arctic Ocean and the Gulf of Mexico excluding the coastal waters off Texas and western Florida.
The submerged lands extending from 3 miles offshore to some undefined outer limit, usually a depth of 200 meters. It is the portion of the shelf under U.S. jurisdiction.
That portion of a continental land mass that constitutes the slope down to the ocean floor. The outer continental shelves are heavily sedimented, and it is believed they contain a large portion of the earth's undiscovered oil and gas.
The part of the continental shelf beyond the line that marks State ownership; that part of the offshore lands under Federal jurisdiction.
an offshore area in the United States that begins where state ownership of mineral rights ends and ends where international treaties dictate.
OCS): The submerged lands extending from the outer limit of the historic territorial sea (typically three miles) to some undefined outer limit, usually a depth of 600 feet. In the United States, this is the portion of the shelf under federal jurisdiction. See Continental Shelf.
Outer Continental Shelf (OCS) are the submerged lands, subsoil, and seabed, lying between the seaward extent of the States' jurisdiction and the seaward extent of Federal jurisdiction. OCS limits are greater than 200 nautical miles but less than either the 2,500 meter isobath plus 100 nautical miles or 350 nautical miles are defined by a line 60 nautical miles seaward of the foot of the continental slope or by a line seaward of the foot of the continental slope connecting points where the sediment thickness divided by the distance to the foot of the slope equals 0.01, whichever is farthest.
