Seafloor videos from the Long Island Sound Phase IIB area (2022)

This data set contains the video files obtained by the Ponar Imaging and Sampling System for Assessing Habitat (PISSAH) developed by the Long Island Sound Mapping and Research Collaborative (LISMaRC) to obtain both physical sediment grab samples and ultra-high definition (4K) video using the latest version of GoPro cameras mounted on the frame in both a forward-looking (GoPro HERO10) and downward-looking (GoPro HERO11) orientation. A three-day survey using the PISSAH deployed from the research vessel Weicker was conducted October 19-21, 2022 to obtain modern seafloor imagery and grab samples in the Phase 1 and II areas. The PISSAH was used to acquire both physical sediment grab samples as well as GoPro video from 18 sites in the Phase I and II areas of the Long Island Sound Cable Fund (LISCF) Seafloor Habitat Mapping Initiative that served as a modern-day assessment of the seafloor communities at these sites. Frame captures from the videos were analyzed for the presence and percent cover of key taxa identified for the Assessing Ecological Change and Resiliency (AECR) project to compare with historical data/imagery from these sites to assess change or stability in these areas of Long Island Sound. The videos in this data set are in MP4 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).
