Bathymetry, acoustic backscatter, and LiDAR data collected in Long Island Sound for the Phase II Long Island Sound Seafloor Mapping Project (NCEI Accession 0167531)

browse graphicPreview graphic
This dataset contains multibeam bathymetry, backscatter, and LiDAR bathymetry and reflectance. These GeoTIFFs represent water depth and acoustic intensity of the seafloor from Phase II of the Long Island Sound (LIS) Benthic Habitat Priority Areas of Interest (AOI) project. The original Phase II datasets were surveyed by NOAA Ship Nancy Foster (R-352), NOAA Ship Thomas Jefferson, and the Navigation Response Team (NRT-5) using 400 khz Reson 7125 multibeam sonars from 2003 to 2014. In 2018, the LIS Cable Fund contracted the State University of New York (SUNY) at Stony Brook School of Marine and Atmospheric Sciences (SoMAS) to fill gaps and resurvey areas where multibeam data was not acceptable with the R/V Pritchard using 400 khz Kongsberg dual-swath EM2040c multibeam sonars in coordination with the NOAA National Centers for Coastal Ocean Science (NCCOS) Biogeography Branch and the NOAA Integrated Ocean and Coastal Mapping (IOCM) Program. The multibeam and LiDAR were corrected, calibrated, and integrated into a seamless 32-bit raster using CARIS and ArcGIS. Backscatter data was collected and mosaicked into a raster using Fledermaus Geocoder Toolbox, ArcGIS 10.4, and PCI Geomatica 2018 software.

Supplemental Information
In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number.
Purpose These integrated bathymetric and backscatter rasters were created to provide the LIS Mapping and Research Collaborative a baseline model for benthic habitat classification in the Phase II Area of Interest. Multibeam acoustic bathymetry, backscatter, and LiDAR bathymetry can be used to study the changing geomorphology of the seafloor, characterizing surficial seafloor features, and delineating benthic habitats.
