Abstract:

Long Island Sound is one of the largest estuaries along the Atlantic coast of the United States. It is a glacially produced, semi-enclosed, northeast-southwest-trending embayment, which is 150 km long and 30 km across at its widest point. Its mean water depth is approximately 24 m. The eastern end of the Sound opens to the Atlantic Ocean through several large passages between islands, whereas the western end is connected to New York Harbor through a narrow tidal strait. Long Island Sound abuts the New York-Connecticut metropolitan area and contains more than 8 million people within its watershed. A study of the modern sedimentary environments on the sea floor within the Long Island Sound estuarine system was undertaken as part of a larger research program by the U.S. Geological Survey (Coastal and Marine Geology Program) conducted in cooperation with the State of Connecticut Department of Environmental Protection and the U.S. Environmental Protection Agency. Knowledge of the bottom sedimentary environments was needed to discern the long-term fate of wastes and contaminants that have been, or potentially will be, introduced into the system and to help understand the distribution of benthic biologic habitats.

Purpose:

This GIS layer represents the researcher's interpretation of the regional distribution of sea-floor sedimentary environments in Long Island Sound. These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic informationsystems (GIS) software to display geologic and oceanographic information.

Lineage:

Process_Step:

Process_Description:

The original interpretation was hand-drawn on mylar based on sidescan-sonar data, seismic-reflection profiles, and sediment sample data collected in the study area. The extent of this orginal work only extended shoreward to the 10m contour interval. This interpretation was then digitized on a digitizing table. This line information was then transferred to Arc/Info where significant cleaning of the data was done. These arcs were then converted to polygons and the attribute information attached. Subsequently, data from the 10 m contour shoreward was incorporated into the original mylar interpretive map. These changes were then digitized and incorporated into the existing Arc/Info coverage. Again, significant cleaning of the arcs as well as assigning the attribute information was done in Arc/Info. The original projection of this work was UTM zone 18, NAD27. For this publication, these data were reprojected into UTM zone 18 NAD 83. This Arc coverage was exported in the e00 format and imported into ArcView. The new theme was then saved in the shapefile format.

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.). 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.

Process_Description:

Added keywords section with USGS persistent identifier as theme keyword (20200908). The original published file was in UTM and reprojected to geographic, with the metadata updated as well. That geographic dataset is no longer available. So the projection was reset to the original UTM projection and links to the geographic version of the data removed. The original metadata did not specify a datum for the UTM projected dataset, so it is assumed to be NAD83. Other elements such as title and point count were reset to the original values. Additional small edits were also made such as changing http to https, providing a generic email in the metadata contact along with adding contact instructions. etc. 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. (20230627)
