  • Wave Energy Period (Annual Mean)

    Wave energy period is a sea state parameter, derived from the zeroth and first negative moments of the frequency spectrum. It is the period corresponding to the weighted average...
  • Beach Nourishment Projects

    Beach Nourishment projects occur throughout coastal states in the United States. These projects can be privately, federally or state funded. Material used in nourishment comes...
  • Light Attenuation (Kd490)

    This dataset represents monthly and annual mean summaries for Kd490 for the time period from 2000/2001 to 2017/2018, depending on the month and data available (see processing...
  • Light Attenuation (Kd(PAR))

    This dataset represents monthly and annual averages of percentage light reaching at 1 m depth relative to surface light (KdPAR). The units are in percentage (%) as surface light...
  • Wind Speed Direction

    Monthly summary of global wind speed and direction averaged from raw data. Raw data available from Jan 1, 1979, to Dec 31, 2010, at hourly temporal resolution, with a spatial...
  • Sea Surface Height

    Monthly and annual summary of global sea surface height anomalies above mean sea surface, averaged from raw data. Raw data available from Oct. 2, 1992 to May 14, 2016, at 5 day...
  • Deep-Sea Coral Observations

    Deep Sea Coral Presence data from around the United States of America 1842 to 2017. Data extracted from the NOAA Deep Sea Coral Research and Technology Program (DSCRTP). Please...
  • Significant Wave Height

    Significant wave height is a spectrally derived time-series, which is the average of the highest third of the waves in a random seaway and roughly corresponds to the mean wave...
  • Coastal Audubon Important Bird Areas

    A compilation of Important Bird Areas (IBAs) for Continental U.S., Hawaii and Alaska, created by the National Audubon Society.
  • Wave Direction (Annual Mean)

    Wave hindcast direction represents the direction of peak in directionally-resolved wave energy flux. Wave hindcast direction values in this dataset are represented in degrees....
  • Bathymetry Digital Elevation Model

    The Digital Elevation Model (DEM) created for the ORT application is a combination of the NCEI Coastal Relief Model (CRM) and the GEBCO (2014) 1 arc-minute 2-dimensional...
  • Ecological Marine Units: Nutrients

    A compilation of ocean nutrient (nitrate, phosphate, and silicate concentrations) data at ¼ degree spatial resolution for the entire United States Exclusive Economic Zone. The...
  • Ecological Marine Units: Water Quality

    A compilation of ocean water quality (temperature, salinity, and dissolved oxygen) data at ¼ degree spatial resolution for the entire United States Exclusive Economic Zone. The...
  • Chlorophyll-a

    This algorithm returns the near-surface concentration of chlorophyll-a (chlor_a) in mg m-3, calculated using an empirical relationship derived from in situ measurements of...
  • Surface Aragonite

    This data layer represents surficial (0m) aragonite saturation state. Aragonite saturation state is measured as the concentration of calcium ions multiplied by the concentration...
  • Highly Migratory Species

    EFH has been designated in 8 regions around the United States and its territories. The process for determining these areas varies regionally. This GIS dataset combines all...
