These maps help define the geological variability of the seafloor (one of the primary controls of benthic habitat diversity); improve 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 provide a detailed framework for future research, monitoring, and management activities. The bathymetric survey interpreted herein (National Oceanic and Atmospheric Administration (NOAA) survey H11255) covers roughly 95 km2 of seafloor in southeastern Long Island Sound. This bathymetry has been examined in relation to seismic reflection data collected concurrently, as well as archived seismic profiles acquired as part of a long-standing geologic mapping partnership between the State of Connecticut and the U.S. Geological Survey (USGS). The objective of this work was to use these acoustic data sets to interpret geomorphological attributes of the seafloor, and to use these interpretations to better understand the Quaternary geologic history and modern sedimentary processes. Purpose: To release 2-m hill-shaded (i.e. sun-illuminated) bathymetric grid generated from multibeam data collected during NOAA survey H11255 in Long Island Sound in UTM zone 18.

Process_Step: Process_Description: The multibeam data for was acquired in XTF (extended Triton data format), recorded digitally through an ISIS data acquisition system, and processed using CARIS HIPS (Hydrographic Image Processing System) software for quality control, to incorporate sound velocity and tidal corrections, and to produce base surfaces at two resolutions: 1-m resolution in the shallower southeastern corner; 2-m resolution over the remaining study area. Among other formats (.tif and .asc), the data were exported in GeoZui format (.gutm) in UTM Zone 18.

A hill-shaded surface was generated from the grid using 3D Analyst Tools with sun illumination from 0 degrees (a direction parallel to most ship tracks to minimize artifacts) and an angle 45 degrees above the horizon, and to vertically exaggerate the surface 10x. The component files were compressed into a zip archive.
