subject:	Phase II LIS Benthic Habitat Mapping Data Submission Final

Abstract: This dataset contains multibeam bathymetry, uncertainty, and backscatter, and LiDAR bathymetry andreflectance. These GeoTiffs with 1x1 meter cell size represent water depth and acoustic intensity of the seafloor from the Phase II Long Island Sound Benthic Habitat Priority Areas of Interest in the Long Island Sound. These datasets were surveyed by the NOAA Ship Nancy Foster R-352, the NOAA Ship Thomas Jefferson, and the Navigation Response Team using  400 khz Reson 7125 multibeam sonars in coordination with the NOAA Biogeography Branch and the Integrated Ocean and Coastal Mapping Branch. The multibeam and LiDAR were corrected, calibrated, and integrated into a seamless 32-bit raster using CARIS and ArcG Backscatter data was collected and mosaicked into a raster using Fledermaus Geocoder Toolbox, ArcGIS 10.4, and PCI Geomatica 2016 software at the Biogeography Branch by NOAA contractors.

Purpose: These datasets were collected in between 2003 and 2015 using multbeam and LiDAR bathymetry to provide the Long Island Sound Mapping and Research Collaborative with mapping data for benthic habitat classification in the Phase II  Area of Interest. Multibeam and LiDAR bathymetry and intensity mosaics are ostensibly important pieces of information when studying the geomorphology of the seafloor, characterizing surficial seafloor features, and delineating benthic habitats and will be used by State and Federal partnerships for natural resource management and marine spatial planning. 

Keep the funding agencies, collaborators, and dataset authors the same. Any more metadata information from the files themselves are included inside the zipped products as a text file.
