Title:
Bathymetry and backscatter grids (GeoTIFF grid format) from central Long Island Sound, LIS Phase IV seafloor mapping, 2022
Abstract:
This bathymetry and backscatter data was collected in support of the Long Island Sound Cable Fund Seafloor Habitat Mapping Initiative, Phase IV, for an area located south of New Haven, CT. Data acquisition was with a Kongsberg multibeam sonar system EM2040P MKII using R/V Connecticut and R/V Seawolf during August, September and December 2022. The data was cleaned and gridded at horizontal resolutions of 1m, 2m and 5m using geodetic datum NAD83 (2011) UTM Zone 18N and the NAVD-88 vertical datum. The files are in GeoTIFF grid format. This study was supported by Contract Number NORTHE8361-001 issued to Stony Brook University by DEEP - Land & Water Resources Division (LWRD), 79 Elm Street, Hartford, CT 06106-5127. This project has been funded wholly or in part by the United States Environmental Protection Agency under assistance agreement LI-00A00579-0 to the Connecticut Department of Energy and Environmental Protection (DEEP).
