The Submerged Lands Act (43 U.S.C. Section 1301 et seq.) grants coastal states title to natural resources located within their coastal submerged lands and navigable waters out to three nautical miles from their coastlines (three marine leagues for Texas and Florida's Gulf of Mexico coastlines). The Submerged Lands Act defines "natural resources" to include oil, gas, and all other minerals, and fish, shrimp, oysters, clams, crabs, lobsters, sponges, kelp, and other marine animal and plant life," yet expressly excludes "water power, or the use of water for the production of power" 43 U.S.C. Section 1301(e). The term "coast line" is "the line of ordinary low water along that portion of the coast which is in direct contact with the open sea and the line marking the seaward limit of inland waters" (43 U.S.C. Section 1301(c)). Some boundary delineations are approximated, including areas in Hawaii, Alaska, and Washington State. The official delineation of the Submerged Lands Act in these locations has not yet been established by BOEM. Please reference BOEM's official Submerged Lands Act Boundary in these locations to determine where this boundary is approximated and where it is official.

U.S. collision regulation boundaries delineate those waters upon which mariners shall comply with the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS) and those waters upon which mariners shall comply with the Inland Navigation Rules. The waters inland of these lines are subject to the Inland Navigation Rules Act of 1980. The waters outside these lines are subject to the International Navigation Rules of the International Regulations for Preventing Collisions at Sea, 1972 (COLREGS). The Coast Guard has the legal authority to effect regulatory changes to COLREGS. Records in this database are derived from descriptions published in the Code of Federal Regulations Title 33, Part 80 and are for planning purposes only.

These data show the geographic representation of Federal and State Waters for the purpose of display in the MarineCadastre.gov OceanReports application. The boundary between state and federal waters was determined by consulting The Submerged Lands Act (43 U.S.C. §§ 1301 et seq.), 48 U.S.C. §§ 1705 and The Abandoned Shipwreck Act (43 U.S.C. §§ 2101). Some boundary delineations based on the SLA were approximated in this data set, including areas in Hawaii, Alaska, and Washington State. Although state boarders do not extend over water, it was necessary to approximate these borders to produce this data set. The boundaries depicted in this data set are for visual purposes only. The placement of these boundaries was extrapolated from the Federal Outer Continental Shelf (OCS) Administrative Boundaries as described here http://edocket.access.gpo.gov/2006/pdf/05-24659.pdf. The delineation between waters under US sovereign territory jurisdiction and that of federal governance is also approximate. Although based upon legislation, these data do not represent legal boundaries, especially in the case of Navassa Island, The Northern Mariana Islands, Baker Island, Howland Island, Johnston Atoll, Kingman Reef, Palmyra Atoll, Wake Islands and Jarvis Island.The seaward limit of this data set is the boundary of the 200nm US Exclusive Economic Zone. The EEZ is measured from the US baseline, recognized as the low-water line along the coast as marked on NOAA's nautical charts in accordance with articles of the Laws of the Sea. These limits are ambulatory and subject to revision based on changes in coastline geometry. This dataset was produced based on an update to the Maritime Limits published in September, 2013. To view the most up-to-date Maritime Limits, please see http://www.nauticalcharts.noaa.gov/csdl/mbound.htm. Navassa Island does not have an EEZ around it, so the seaward extent of the federal waters surrounding it were based on the 12 mile offshore boundary of the USFWS National Wildlife Refuge established on the island. All data is displayed in WGS_1984_World_Mercator. Area calculations for all states except Alaska were completed in the same projection. Area calculations for Alaska were completed in Alaska Albers Equal Area Conic.

This dataset represents US states and equivalent territorial units which have at least one coastal border.

These data represent the extent of the nation's coastal zone, as defined by the individual states and territories under the Coastal Zone Management Act of 1972 (CZMA). The CZMA was established to preserve, protect, develop, and where possible, to restore or enhance the resources of the nation's coastal zone. The zone generally extends seaward to the boundary of the Submerged Lands Act. The zone extends inland from the shorelines only to the extent necessary to control shorelands that have a direct and significant impact on coastal waters. Lands held in trust by the Federal Government have been included in this boundary unless otherwise noted, as accurately representing these could be erroneous. State jurisdiction extends to 3nm, except for Texas, Puerto Rico and Florida's Gulf coast extends to 9nm. Great Lakes states have jurisdiction to the international boundary with Canada. CZMA applies in EEZ through federal consistency. This boundary is unofficial. For precise, regulatory boundaries, please contact the state or territorial coastal program office.

These data show the location of ocean observing assets within U.S. waters, and the physical parameters generally collected at each platform or gauge.

These data show the location of probable oil or gas geologic structures (plays) mapped within the outer continental shelf of the United States. Plays are groups of known or postulated subsurface hydrocarbon accumulations that share common geologic, geographic, and temporal properties, such as history of hydrocarbon generation, migration, reservoir development, and entrapment. Seismic surveys were used to analyze the Unrecovered Technically Recoverable Resource. Plays are displayed as two-dimensional features, but may overlap vertically allowing for multiple plays in the same area.

Anchorages are well-defined navigable waters where a vessel may safely drop anchor. The size, shape, and conditions for use of these areas can vary widely. Generally, anchorages are not used for an indefinite duration, nor are they routinely used for maintenance, repair, overhaul, bunkering, or sea trials.

This layer shows coastal channels and waterways that are maintained and surveyed by the U.S. Army Corps of Engineers. These channels are necessary transportation systems that serve economic and national security interests. The possibility of silting is always present. Local authorities should be consulted for the controlling depth. NOAA Charts frequently show controlling depths in a table, which is kept current by the U.S. Coast Guard Local Notice to Mariners.
