39494 se_atl_efh_backscatter_10 Data Set Published / External 37204 se_atl_efh Project Completed 2012 This dataset contains unified Multibeam Backscatter GeoTiffs with 4x4 meter cell resolution describing the geomorphology of 15 areas along the shelf edge off the South Atlantic Bight where NOAA South East Fisheries Independent Survey (SEFIS) are conducting research on Red Snapper (lutjanus campechanus). The multibeam data covers a total of 232 sq km and was collected in 2010 by the NOAA Ship Nancy Foster with a hull-mounted Kongsberg Simrad EM 1002 multibeam echo sounder (95 kHz). It was processed by NOAA's NOS/NCCOS/CCMA Biogeography Branch using FlederMause 7 Geocoder and Hypack 2012 Geocoder. The processed backscatter data was used to generate an 8 bit GeoTiff that was exported to ArcGIS 10 for aditional masking and stretching operations. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats.The spatial products developed in this project will provide ocean managers and researchers with essential fish habitat information. 801 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 > Backscatter Theme CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Aquatic Habitat > Reef Habitat > Description Theme CoRIS Theme Thesaurus EARTH SCIENCE > Oceans > Bathymetry/Seafloor Topography > Bathymetry > Backscatter Theme NOS Data Explorer Topic Category Bathymetry/Topography Theme Backscatter Theme Bathymetry Theme Benthic Theme Biogeography Theme EFH Theme Florida Theme GIS Theme Georgia Theme Grays Reef Theme Grid Theme Habitat Theme MARMAP Theme MBES Theme Multibeam Theme NOAA Theme NOAA Ship Nancy Foster Theme Ocean Explorer Theme Raster Theme Red Snapper Theme Reef Theme SEFIS Theme Seafloor Theme Simrad EM1002 Theme SoNAR Theme South Atlantic Bight Theme South Carolina Theme Southeast Atlantic Temporal 2010 Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Florida Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > Georgia Spatial CoRIS Place Thesaurus COUNTRY/TERRITORY > United States of America > South Carolina Spatial Continental Shelf Spatial South Atlantic Ocean National Centers for Coastal Ocean Science Silver Spring MD Data Set None Planned raster digital data These data were prepared by an agency of the United States Government.

Microsoft Windows 7; ESRI ArcCatalog 10.0 This GeoTiff is sourced from a raw multibeam 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 backscatter snippet data from the raw multibeam was used to create an accoustic intensity surface. As the survey was not conducted to meet IHO standards, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

Multibeam data were acquired in .all format with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz). Backscatter collection was enabled. Line spacing for acquisition was three times the water depth, and data was retained out to 60 degrees from nadir. 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 processed using NOAA's Velocwin V8.85 software, then applied directly to the raw data. Positioning was obtained using Trimble Zephyr GPS receivers. 2012-01-01T00:00:00 2 Raw .all data was uploaded into Fledermaus Geocoder Toolbox to extract snippets. 2012-01-01T00:00:00 Geocoder Backscatter Mosaic 3 Beam time series snippet data was processed, cleaned, and mosaiced in FMGT and exported as an 8-bit GeoTiff 2012-01-01T00:00:00 Raw Multibeam Data gov.noaa.nmfs.inport:39494 Tyler Christensen 2017-04-05T12:52:51 SysAdmin InPortAdmin 2025-05-15T19:16:06 2017-11-09 National Centers for Coastal Ocean Science NCCOS 1002 Public No No 2017-11-09 1 Year 2018-11-09
