38859 NF08_PR_Mona_Backscatter_3m_Metadata Data Set Published / External 37205 SeafloorMapping_USCaribbean_2004toOngoing Project Completed 2008-09 This image represents a 3 meter resolution backscatter mosaic of selected portions of seafloor around Mona Island, Puerto Rico. 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 in Puerto Rico from 2/25/08 to 3/8/08. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2008. 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 19 north, datum NAD83. The backscatter component of the bathymetry data was geometrically and radiometrically corrected using Geocoder 3.2.1 software. Acoustic backscatter mosaics are 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, dependent 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 by CCFHR during the fifth year of an ongoing NOAA scientific research mission in the US Caribbean to characterize nearshore to 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 2008 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 Puerto Rican seafloor. 725 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 Benthic Theme Biogeography Theme Coral Theme GIS Theme Geotiff Theme Habitat Theme IOCM Theme Integrated Ocean and Coastal Mapping Theme MBES Theme Multibeam Theme NOAA Theme Nancy Foster Theme Puerto Rico Theme Raster Theme Reef Theme Seafloor Theme Simrad EM 1002 Theme Sonar Temporal 2008 Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Puerto Rico > Isla de MOna (18N067W0002) Spatial placekt: CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > Caribbean Sea /North Atlantic Ocean > Puerto Rico > Isla de MOna (18N067W0002) Spatial placekt: CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > Caribbean Sea > Puerto Rico > Isla de MOna (18N067W0002) Spatial Isla de Mona Spatial PR 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.

See Data Acquisition and Processing Report (DAPR) for NF-08. This ESRI Geotiff is sourced from a 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 Geotiff. 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, dependent on project area and depth, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

Data were collected aboard the NOAA ship Nancy Foster from 2/25/08 to 3/08/08. Multibeam data for 2008 were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz). Backscatter snippet collection was enabled. Line spacing for acquisition was three times the water depth, and data was retained out to 55 degrees from nadir for areas deeper than 55 meters and 60 degrees from nadir for areas shallower than 55 meters. 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, then applied directly to the raw data. 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 Multibeam Data NF-08-04 2008-01-01T00:00:00 Raw Multibeam Data NF-08-04 2 Raw Simrad data (.all format) were converted and processed using CARIS HIPS and SIPS v6.1 software, resulting in a CARIS HDCS format dataset with all correctors applied. Attitude and SWMB data was cleaned of fliers, and SWMB data was reviewed in subset mode by a NOAA contractor. | Source Produced: NF-08-04 HDCS Processed Multibeam Data 2008-01-01T00:00:00 Raw Multibeam Data NF-08-04 3 Acoustic backscatter mosaics are an important piece of information when characterizing surficial seafloor features and delineating benthic habitats. The multibeam backscatter data were corrected for geometric and radiometric distortions using Geocoder 3.2.1. 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. The final mosaics were exported as an ESRI Geotiff and XYB files (i.e., X,Y locations in NAD83 UTM Zone 19N and Backscatter values as measured in decibels dBs). | Source Produced: NF08_mona_backscatter_3m.tif 2008-01-01T00:00:00 NF-08-04 HDCS Processed Multibeam Data gov.noaa.nmfs.inport:38859 Tyler Christensen 2017-04-05T12:49:21 SysAdmin InPortAdmin 2025-05-15T19:16:12 2018-02-08 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2018-02-08 1 Year 2019-02-08
