38895 NF11_USVI_ShelfSTJ_Bathy_4m_Metadata Data Set Published / External 37205 SeafloorMapping_USCaribbean_2004toOngoing Project Completed 2011-11 This dataset contains a GeoTIFF with 4x4 meter cell size representing the bathymetry of a sharply sloping swath of the St. John Shelf, a selected portion of seafloor south of St. John, USVI, derived from data collected from 3/28/2011 to 4/14/2011. 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 south of St. Thomas and St. John, USVI, from 3/28/11 to 4/14/2011. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) for water depths greater 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 CUBE. A BAG file was exported from the BASE surface, and converted to a GeoTIFF in ESRI ArcMap 10.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 NF-11-01 during the seventh 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 2004-2011 missions 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 USVI seafloor. 761 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 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 Raster Theme Reef Theme Seafloor Theme Sonar Theme US Virgin Islands Theme USVI Temporal 2011 Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > U.

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 3/28/2011 to 4/14/2011, as project number NF-11-01. Multibeam data was acquired in Simrad .hsx and .7k formats with hull-mounted Reson 7125 and Kongsberg Simrad EM 1002 multibeam echosounders (400 kHz). Simrad 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) primary tide stations at Charlotte Amalie, VI (9751639) and Lime Tree Bay, VI (9751401). 2011-01-01T00:00:00 Raw Multibeam Data NF-11-1 2 Raw .hsx and .all data were converted and processed using CARIS HIPS v7.0 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. 2011-01-01T00:00:00 NF-11-01 HDCS Processed Multibeam Data 3 After being submitted to CCMA by the contractor, CARIS HIPS v7.0 was used to generate a CARIS BASE surface (similar to a DTM), based on CUBE (Combined Uncertainty and Bathymetry Estimator) from the processed HDCS data. A .BAG file (Bathymetric Attributed Grid) was also exported from CARIS using the "BASE Surface to BAG" tool. 2011-01-01T00:00:00 NF-11-01 CARIS BASE Surface 4 The BAG file was opened in ArcMap 10 and exported as a GeoTIFF. | Source Produced: NF11W00216_1002_Bathy4m.tif 2011-01-01T00:00:00 NF-11-01 CARIS BASE Surface gov.noaa.nmfs.inport:38895 Tyler Christensen 2017-04-05T12:49:37 SysAdmin InPortAdmin 2025-05-15T19:15:59 2018-02-08 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2018-02-08 1 Year 2019-02-08
