Navigation data (shapefile format) for R/V Lowell Weicker surveys, western Long Island Sound (2023)

These shapefiles provides the survey boat navigation data during a four-day survey using the Ponar Imaging and Sampling System for Assessing Habitat (PISSAH) deployed from the Research Vessel Weicker conducted from June 12-16, 2023. The PISSAH system was used to acquire both physical sediment grab samples as well as the GoPro video from 60 sites in the Phase III area of the Long Island Sound Cable Fund (LISCF) Seafloor Habitat Mapping Initiative. These sites were identified in the Phase IIIA area 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 files are 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).
