Outer Continental Shelf: The Federal Government administers
the submerged lands, subsoil, and seabed, lying between the seaward extent of the States'
jurisdiction and the seaward extent of Federal jurisdiction.
State jurisdiction is defined as
follows:

Texas and the Gulf coast of Florida are extended 3 marine leagues (9 nautical miles) seaward from the baseline from which the breadth of the territorial sea is measured.

Louisiana is extended 3 imperial nautical miles (imperial nautical mile = 6080.2 feet) seaward of the baseline from which the breadth of the territorial sea is measured.

All other States' seaward limits are extended 3 nautical miles (approximately 3.3 statute miles) seaward of the baseline from which the breadth of the territorial sea is measured.
|
Federal jurisdiction is defined
under accepted principles of international law. The seaward limit is defined as the
farthest of 200 nautical miles seaward of the baseline from which the breadth of the
territorial sea is measured or, if the continental shelf can be shown to exceed 200
nautical miles, a distance not greater than a line 100 nautical miles from the 2,500-meter
isobath or a line 350 nautical miles from the baseline.
Outer Continental Shelf limits 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.
