Description:
Abstract:
The U.S. Geological Survey, in cooperation with the National Oceanic and Atmospheric Administration and the Connecticut Department of Environmental Protection, has produced detailed geologic maps of the sea floor in Long Island Sound, a major East Coast estuary surrounded by the most densely populated region of the United States. These studies have built upon cooperative research with the State of Connecticut that was initiated in 1982. The current phase of this research program is directed toward studies of sea-floor sediment distribution, processes that control sediment distribution, nearshore environmental concerns, and the relation of benthic community structures to the sea-floor geology. Acoustic data collected during hydrographic surveys provide valuable base maps for marine geological interpretations. 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. This shapefile represents the interpretation of modern processes and features found on the bathymetric data set of study area H11250, The Race. Sharing of multibeam bathymetric data (NOAA Ship Thomas Jefferson, October 2003 survey H11250) between NOAA's Atlantic Hydrographic Branch and the State of Connecticut/USGS Geologic Mapping Cooperative has yielded a new geologic perspective on approximately 93.75 km2 of the sea floor in the vicinity of The Race, an area where the Orient Point-Fishers Island segment of the Harbor Hill-Roanoke Point-Orient Point-Fishers Island-Charlestown Moraine marks the dividing line between easternmost Long Island Sound and northwestern Block Island Sound. The detailed bathymetry collected by NOAA has been examined in relation to seismic data collected concurrently, as well as archive data collected as part of a long-standing geologic mapping partnership between the State of Connecticut and the U.S. Geological Survey (USGS). These new data reveal previously unknown details of the physical character of the sea floor such as bedforms, moraines, and ship wrecks. These features have been mapped as interpretive GIS data layers that can be used in conjunction with the multibeam grid H11250G or related shaded relief graphics (h11250gcolhs.tif).
Purpose:
To release interpretations the modern 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 an interpretaion of some modern processes and features (sand wave fields, dump sites) that shape 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.
Supplemental_Information:
Original bathymetric data was collected via a Simrad EM1002 multibeam system mounted on the hull of the Thomas Jefferson which acquired over 560 km of survey lines from the deeper water (>20 m) parts of the study area. Two 29-foot launches with hull-mounted Reson systems were deployed from the ship and were used to acquire an additional 637 km of survey lines from the shallower areas.

Horizontal_Positional_Accuracy_Report:
Navigation was by differential GPS; positional accuracy to less than 10 m. Interpreted polygons are accurately located given the nature and scale of the features. Previously collected seismic data used to aid the interpretation of the multibeam data was collected by ship navigated by Loran C which is less positional accuracy than GPS.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Minor fixes to the attribute format for some attributes were needed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
