Source data were acquired during National Oceanic and Atmospheric Administration (NOAA) survey H11250. Please acknowledge NOAA as the originator of the dataset from which this dataset was derived.
To release interpretations the geologic features based on data collected during NOAA survey H11250 in easternmost Long Island Sound and westernmost Block Island Sound, in geographic. This GIS layer serves a starting point for a geologic study of the area in that it shows the geologic units that subcrop and influence the bathymetry and geometry of the Race, Long Island Sound. The detailed bathymetic data and their interpretations serve many purposes, including: (1) defining the geological variability of the sea floor, which is one of the primary controls of benthic habitat diversity; (2) improving our understanding of the processes that control the distribution and transport of bottom sediments and the distribution of benthic habitats and associated infaunal community structures; and (3) providing a detailed framework for future research, monitoring, and management activities. The bathymetric data models also serve as base maps for subsequent sedimentological, geochemical, and biological observations, because precise information on environmental setting is important for selection of sampling sites and for accurate interpretation of point measurements.
