This GeoTiff is a bathymetry model of the seafloor of Northeast Puerto Rico that contains the shallow water area (0-35m deep) of the Northeast Ecological Reserve: including the waters off of Fajardo and Luqillo, to the Former Roosevelt Roads Navy Base, the Vieques Sound, La Cordillera Reserve, the Luis Pena Reserve, and the waters around Culebra Island. The bathymetry model was created by integrating soundings from several different sources (1900-2013), including high resolution coastal LiDAR, NOAA Single-beam and multibeam bathymetry, and historical lead line soundings. In order to combine the many different data sources and densities, the model consists of three different resolutions (4m, 20m and 100m). In addition to the depth model, a depth uncertainty layer was also produced. The bathymetry model is the basis for the benthic habitat map which was produced by remote sensing analysis tools that delineated the habitats using a semi-automated classification process.

This GeoTiff is a representation of seafloor topography in Northeast Puerto Rico derived from a bathymetry model with a principle component analysis (PCA). The area covered includes the shallow water area (0-60m deep) of the Northeast Ecological Reserves: including the waters off of Fajardo and Luqillo, to the Former Roosevelt Roads Navy Base, the Vieques Sound, La Cordillera Reserve, the Luis Pena Reserve, and the waters around Culebra Island. The PCA image was created using Envi 5.1, and is based on nine morphometric derivatives of the bathymetry, such as slope, curvature and rugosity. The bathymetry model was created by integrating soundings from several different sources (1900-2013), including high resolution coastal LiDAR, NOAA Single-beam and multibeam bathymetry, and historical lead line soundings, into a multi resolution (4m, 20m, 100m) depth model. The PCA image was used to delineate the different shallow water benthic habitats of NEPR.

This dataset contains a unified ESRI Geotiff with 2x2 meter cell size representing the bathymetry of a selected portion of seafloor southwest of Vieques Island, derived from data collected in March and April 2009. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data around Vieques Island from 3/26/09 to 4/2/09. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) for water depths greater than 75 meters, and with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of less than 75 meters. It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.x as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate the final ESRI Geotiff. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Attitude and sound velocity correctors applied to the data. Verified tides were not applied to the data, leaving the depth values referenced to the ellipsoid. The imagery is projected in the UTM Zone 17 north, NAD83 datum. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. The CARIS Export option "BASE Surface to Image" was then used to create a GeoTiff of the priority areas.
