38872 NF09_PR_ElSecoVieques_Bathy_1m_Metadata Data Set Published / External 37205 SeafloorMapping_USCaribbean_2004toOngoing Project Completed 2009-12 This dataset contains a unified ESRI Geotiff with 1x1 meter cell size representing the bathymetry of El Seco, a selected portion of seafloor east 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. This multibeam data was collected as IOCM (Integrated Ocean and Coastal Mapping) project NF-09-01 during the sixth 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 2004-2009 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. 738 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 MBES Theme Multibeam Theme NOAA Theme NPS Theme Nancy Foster Theme Raster Theme Reef Theme Reson 7125 Theme Seafloor Theme Simrad EM 1002 Theme Sonar Theme US Virgin Islands Theme USVI Temporal 2004 Temporal 2005 Temporal 2006 Temporal 2007 Temporal 2008 Temporal 2009 Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Puerto Rico > Puerto Rico (18N066W0000) Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Puerto Rico > Vieques > Vieques Island (18N065W0002) Spatial placekt: CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > U.

See Data Acquisition and Processing Report (DAPR) for NF-09-01. This ESRI 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 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 was collected aboard the NOAA ship Nancy Foster from 3/26/09 to 4/2/09. Multibeam data were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz) for water depths greater than 75 meters and in .pds format with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of less than 75 meters. 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 for the EM1002, and 128 degrees from nadir for the Reson 7125, depending on project area. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model 320 V4 inertial measurement unit (IMU) and associated Trimble GPS antennas. Sound velocity profiles were acquired with a Seabird Electronics SeaCat SBE19P CTD profiler and a Reson SVP 70 and processed using NOAA's Velocwin V8.85 software, then applied directly to the raw data. Positioning was obtained using Trimble Zephyr GPS receivers and an auxiliary Trimble DSM 132 DGPS 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-09-01 2009-01-01T00:00:00 Raw Multibeam Data NF-09-01 2 Raw .pds and .all data were converted and processed using CARIS HIPS v6.0 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. | Source Produced: NF-09-01 HDCS Processed Multibeam Data 2009-01-01T00:00:00 Raw Multibeam Data NF-09-01 3 After being submitted to CCMA by the contractor, CARIS HIPS v6.0 was used to generate a CARIS BASE surface (similar to a DTM), based on weighted swath angle, from the processed HDCS data. Then CARIS export tool "BASE Surface to ASCII" was used to export a comma delimited ASCII XYZ file, with Easting, Northing, and Depth values, using ground position units (NAD83 UTM zone 20N). | Source Produced: NF-09-01 CARIS BASE Surface 2009-01-01T00:00:00 NF-09-01 CARIS BASE Surface 4 The ASCII XYZ file was opened in ArcMap 9.x and the 'Display XY Data' option was used to add the XY data as an event with spatial reference NAD83 UTM zone 20N. Finally, the ArcToolbox 9.x conversion tool "Feature to Raster" was then used to convert the XY event into an ESRI Geotiff, based on the depth field Z. These steps were accomplished using an inhouse Arc script which combined these functions and allowed bulk processing. | Source Produced: NF09_ElSeco_Bathy_1m.tif 2009-01-01T00:00:00 NF-09-01 CARIS BASE Surface gov.noaa.nmfs.inport:38872 Tyler Christensen 2017-04-05T12:49:27 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
