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

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

Mean wave power density estimates represent naturally available US wave energy, derived from measurements observed during a 51-month study period. Measurements were taken from 42,000 grid points out to a distance of 50 nautical miles from shore. Values represent the average instantaneous power generated by a meter length of wave crest per grid point. In accordance with accepted global practice, wave power density is measured in kilowatts per meter of wave crest aggregated across a unit diameter circle. Data were classified using quantiles. Bathymetric effects are known to have a large effect on wave characteristics at depths shallower than ~20m on the east coast and ~50m on the west coast. Reliable site-specific information in shallow waters can only be produced using results from models with higher spatial resolution that include shallow-water physics. Results may not be accurate in the shallower waters of the inner continental shelf.

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.

A shore-based station that provides identity, time synchronization, and text messages, which report (message 4) every ten seconds and are identified by a 00MIDxxxxx MMSI. These stations can also transmit AIS ATON Reports (message 21) and Application Specific Messages (ASM, message 6 and message 8) for meteorological or hydrological information, marine safety information, etc. (see the IALA Application Specific Message Collection). The Coast Guard Light List maintains a list of U.S. stations that also act as AIS ATONs or transmit ASMs. In the United States, these stations are solely operated by the U.S. Coast Guard (USCG) in the Nationwide Automatic Identification System, a nationwide network that supports all USCG missions and is designed to enhance the Coast Guards maritime domain awareness of vessels operating in or approaching the nations waterways, ports, and infrastructure. This network, which comprises 130-plus base stations and 150-plus USACE inland stations, collects over 120 million AIS messages daily and shares information with other government agencies, industry, academia, and coastal planners.

These data show the location of available and discontinued ocean disposal sites within U.S. waters. Contemporary ocean disposal sites generally accept clean dredged material (sediment) collected during navigation channel improvement projects. These projects are sponsored and-or regulated by federal and state agencies. The terminology and practices used in ocean disposal have changed considerably over time. The values in the Primary Use field in this database show some of that variability.

Map of the operational power plants in California that are greater than 1 MW in capacity and operational in 2018. This data is aggregated from the Quarterly Fuel and Energy Report (QFER) and Wind Performance Reporting System (WPRS) datasets.,

These data show the local of well-known places along the coast of the United States and its territories.

This data set contains vector lines representing coastal hydrography used in the creation of the Environmental Sensitivity Index (ESI) for South Carolina. This data set comprises a portion of the ESI data for South Carolina. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the HYDROP data layer, part of the larger South Carolina ESI database, for additional ESI information.

This data set contains vector lines representing coastal hydrography features that are not captured in the HYDROP polygon data layer. Typically, the features found in the HYDROL data layer are piers, breakwaters, and inland rivers and creeks. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the HYDROP (Hydrography Polygons) data layer for additional shoreline/hydrography information.
