LISCF Phase IIIA survey area boundary (shapefile format) for R/V Lowell Weicker surveys, western Long Island Sound (2023)

This shapefile provides the boundary of the Phase IIIA survey area of the Long Island Sound Cable Fund (LISCF) Seafloor Habitat Mapping Initiative. Phase IIIA sites within the boundary were identified based upon an analysis of existing acoustic backscatter data obtained from multiple surveys by NOAA that exhibited what appeared to be inconsistent gray scale settings. The navigation boundary file is in ESRI Shapefile format. Funding was provided by the Long Island Sound Cable Fund Seafloor Habitat Mapping Initiative administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).
