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

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

These data show bathymetric contours (isobaths) that help characterize the general physiographic patterns of the seafloor. Contour intervals are every 10 m from zero to -100 m, every 25 m from -100 m to -500 m, and every 100 m from -500 m to full depth. The DEM utilized was the Global Multi-Resolution Topography Synthesis which is a multi-resolution gridded global Digital Elevation Model that includes cleaned processed ship-based multibeam sonar data at their full spatial resolution (approximately 100m in the deep sea).

These data show the 17 national marine sanctuaries in the United States. The National Marine Sanctuaries Act (NMSA) authorizes the Secretary of Commerce to designate and protect areas of the marine environment with special national significance due to their conservation, recreational, ecological, historical, scientific, cultural, archeological, educational or esthetic qualities as national marine sanctuaries.

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 summarizes 2015 Ocean Economy employment statistics for the U.S. coastal states by breaking down each ocean economic indicator per each ocean sector. The dataset also provides percent employment and percent GDP by sector. This percentage is a percent of the ocean sector compared to the total Ocean Economy for each state. This information was harvested from the Economics: National Ocean Watch (ENOW) time-series data on the ocean and Great Lakes economy, derived from the Bureau of Labor Statistics and the Bureau of Economic Analysis. ENOW data measures four economic indicators: Establishments, Employment, Wages, and Gross Domestic Product (GDP) for six economic sectors that are dependent on the oceans and Great Lakes, including: Marine Construction, Living Resources, Offshore Mineral Extraction, Ship and Boat Building, Tourism and Recreation, and Marine Transportation.

These data depict a wave energy resource characterization for the US Exclusive Economic Zone. This climatology is based on a multi-resolution 32 year hindcast that used the WaveWatchIII and Simulating WAve Nearshore (SWAN) wave models. A collection of five variables are reported at the annual and monthly intervals. Statistics for each variable are provided as point and hexagon features.

Monthly and annual U and V vectors were summarized for 14 unique depth levels from daily means using the HYCOM and NCODA Global 1/12-degree Reanalysis. The U vector (m/s) is to the East and the V vector (m/s) is to the North. Current magnitude (m/s) was calculated using the daily U and V vectors. Descriptive statistics of mean, variance, standard deviations, minimum, and maximum were calculated for each month from the twenty years of data using the daily means (1992-2012). Mean, variance, and standard deviation was calculated for the annual summary period (1992-2012). The mean direction in degrees (with 0 = North) was calculated from the summarized U and V vector means, and represents the direction that the current is moving toward. The 1/12-degree global HYCOM+NCODA Ocean Reanalysis was funded by the U.S. Navy and the Modeling and Simulation Coordination Office. Computer time was made available by the DoD High Performance Computing Modernization Program. The output is publicly available at http://hycom.org.

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.

Offshore state lateral boundaries define part of the geographic extent of the submerged lands that a state holds and manages in the public trust. Well-defined boundaries help a state manage its natural resources and statutory obligations with a measured amount of certainty. However, state lateral boundaries, both on land and at sea, have not always been stable and well defined. The historic record often shows conflicting borders that have led to interstate disagreements, court cases, and in some instances lingering stalemates. These data show the approximate position of a states offshore lateral boundary based on official and unofficial sources. Some boundaries have been omitted when a sufficient data source could not be found.
