Resource Abstract:
- description: Nearshore areas within Long Island Sound are of great interest to the Connecticut and New York research and management
communities because of their ecological, recreational, and commercial importance. However, although advances in multibeam
echosounder technology permit the construction of detailed digital terrain models of seafloor topography within deeper waters,
limitations inherent with collecting multibeam data make using this technology in shallower waters (<10-m deep) more difficult
and expensive. These limitations have often resulted in gaps of no data between multibeam bathymetric datasets and the adjacent
shoreline. To address this problem, complete-coverage multibeam bathymetry acquired offshore of New London and Niantic Bay,
Connecticut, has been integrated with hydrographic LIDAR acquired along the nearshore. The result is a more continuous seafloor
perspective and a much smaller gap between the digital bathymetric data and the shoreline. These datasets are provided as
ESRI grid and GeoTIFF formats in order to facilitate access, compatibility, and utility.; abstract: Nearshore areas within
