38897 NF12_PR_NEReserveNorth_Backscatter_8m_Metadata Data Set Published / External 37205 SeafloorMapping_USCaribbean_2004toOngoing Project Completed 2012-12 This image represents a 8 meter resolution backscatter mosaic of of a sharply sloping swath of the St. John Shelf, south of NE Reserve, offshore of Fajardo, Puerto Rico. NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the in the Northeast Reserve from 4/04/2012 to 4/20/2012. Data was acquired with a hull-mounted Kongsberg 1002 multibeam echosounder (95 kHz) and 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 from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Fledermaus Geocoder Toolbox 7.3 software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards. This multibeam data was collected as IOCM (Integrated Ocean and Coastal Mapping) project M-I907-NF-12 during the ninth year of an ongoing NOAA scientific research mission in the US Caribbean to characterize midshelf and deep water coral reef habitats at depths down to 1,000 meters. The mission purpose is to better understand the resources within the surveyed reef habitats, and ultimately develop species utilization models linking physical habitats with biological information. The multibeam backscatter, multibeam bathymetry, and ground truth video footage collected during the 2011 mission will be used internally to characterize sea floor topography and to create benthic habitat maps, helping NOAA meet its mapping commitment to the US Coral Reef Task Force. The resulting publicly-distributed data is also a contribution to the greater scientific community interested in the US Caribbean seafloor. 763 Theme ISO 19115 Topic Category elevation Theme ISO 19115 Topic Category environment Theme ISO 19115 Topic Category geoscientificInformation Theme ISO 19115 Topic Category imageryBaseMapsEarthCover Theme ISO 19115 Topic Category oceans Theme CoRIS Discovery Thesaurus Geographic Information > Bathymetry Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Aquatic Habitat > Reef Habitat > Description Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Bathymetry/Seafloor Topography > Bathymetry Theme NOS Data Explorer Topic Category Bathymetry/Topography Theme Backscatter Theme Bathymetry Theme Benthic Theme Biogeography Theme Coral Theme GIS Theme Geotiff Theme Habitat Theme IOCM Theme Integrated Ocean and Coastal Mapping Theme Kongsberg EM 1002 Theme MBES Theme Multibeam Theme NOAA Theme NPS Theme Nancy Foster Theme Northeast Reserve Theme Puerto Rico Theme Raster Theme Reef Theme Seafloor Theme Sonar Temporal 2012 Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Puerto Rico > Fajardo Spatial Caribbean Sea Spatial Fajardo National Centers for Coastal Ocean Science Silver Spring MD Data Set As Needed raster digital data These data were prepared by an agency of the United States Government.

This GeoTIFF is sourced from a CARIS gridded dataset. The original full-resolution multibeam data was used to create a downsampled uniform-resolution CARIS BASE (Bathymetry Associated with Statistical Error) surface grid with a best depth component. The downsampled grid nodes from that depth surface were then exported and used to generate the ESRI Grid. Some positional shifts may have occurred between the original data points and the transformed grid. While the project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on project area and depth, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

Data was collected aboard the NOAA ship Nancy Foster from 4/04/2012 to 4/20/2012, as project number M-I907-NF-12. Multibeam data was acquired in Kongsburg .ALL formats with hull-mounted Em 1002 multibeam echosounders (95 kHz). Backscatter snippet collection was enabled. Line spacing for acquisition was three times the water depth, and data was retained out to 60 degrees from nadir, depending on project area. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model 320 inertial measurement unit (IMU) and associated Trimble GPS antennas. Sound velocity profiles were acquired with a Seabird Electronics SeaCat SBE19P CTD profiler and processed using Seabird Seaterm software. Positioning was obtained using Northstar 941X GPS receivers with differential correctors from U.S. Coast Guard CORS beacon Isabel, Puerto Rico. Data was reduced to Mean Lower-Low Water (MLLW) using final approved tides from NOAA COOPS, based on National Water Level Observation Network (NWLON). | Source Produced: Raw .ALL Multibeam Data 2012-04-01T00:00:00 Raw .ALL Multibeam Data 2 The multibeam backscatter data were corrected for geometric and radiometric distortions using Fledermaus Geocoder Toolbox 7.3. In particular, the following corrections were applied where appropriate and when artifacts were evident: AVG Trend, TX Power and RX Gain, Area Correction, Spreading, Slant-Range and Extracted Beam Pattern. As no theoretical beam pattern for the Kongsberg Simrad 1002 system exists, it was extracted from a mapped area that was flat and had a relatively uniform (sandy) substrate. Individual lines were also truncated based on ping number and/or angle of incidence where appropriate. A raster backscatter mosaic was created. | Source Produced: NF12 Processed Backcatter Data 2012-10-01T00:00:00 Raw .ALL Multibeam Data 3 The final mosaics were exported as geotiffs in NAD 1983 UTM Zone 20N and Backscatter values as relative decibel outputs in 8 bit 0-255 colorscale. | Source Produced: NF12_PR_1002_Backscatter_8m.tif 2012-12-01T00:00:00 NF12 Processed Backcatter Data gov.noaa.nmfs.inport:38897 Tyler Christensen 2017-04-05T12:49:38 SysAdmin InPortAdmin 2025-05-15T19:16:06 2018-02-08 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2018-02-08 1 Year 2019-02-08
