The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Connecticut Department of Energy and Environmental Protection (CT DEEP), is producing detailed geologic maps of the coastal sea floor. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During April-May 2009 NOAA completed hydrographic survey H12013 offshore of the entrance to the Connecticut River, and during November 2009 and April 2010 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth surveys see: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-059-FA and http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-010-FA
To release an interpretation of sedimentary environments based on bathymetry data collected during NOAA survey H12013 and sediment samples and bottom photography collected during USGS surveys 2009-059-FA and 2010-010-FA in eastern Long Island Sound, in a geographic, WGS84 coordinate system. These data can be used to provide information on surface geology and sedimentary processes.

No additional checks for consistency were performed on these data.
All collected data with the study area were processed and used to produce this dataset.
Navigation of the underlying data on which the interpretation is based was by differential GPS. Interpretation good to 1:24,000.
The source information specified in the metadata appears to actually cover two datasets. One from NOAA and one from USGS.

The source information was incomplete and had to be modified to meet the standard.

Ground condition, however, calendar date is for the bottom samples and photography. Multibeam bathymetry and sidescan sonar backscatter used in the interpretation were collected during 2009.
h12013_int2m_geo.tif, h12013_seddata.shp, h12013_botphotos.shp, h12013_1msss_geo.tif: inferred from information in the first process step as this was not provided in the original metadata.
The original acoustic data acquired during NOAA survey H12013 aboard the NOAA ship Thomas Jefferson and the portion of the sediment samples and bottom photography collected during USGS surveys 2009-059-FA and 2010-010-FA that fall within the study area.
GeoTIFF images of the multibeam-bathymetry and sidescan-sonar data from survey H12013 and the point data layer from grain-size analyses and textural descriptions of sediments collected from USGS cruises 2009-059-FA and 2010-010-FA in the survey area were imported into the ArcView 3.3 GIS project view. Sedimentary environments were interpreted based on geomorphology and relief in the bathymetry, backscatter intensity of the sidescan sonar, and on the bottom photography and textural data. The individually interpreted environments (Erosion or Nondeposition, Coarse Bedload Transport, and Sorting and Reworking) were outlined using the available graphic tools then converted to an ESRI shapefile using ArcView 3.3. Polygons were traced at a scale of 1:4,000 to 1:5,000; union and subtraction edits were conducted at 1:5,000 to 1:8,500 scales; use of this interpretation data layer is not recommended at scales of less than 1:24,000.

ArcGIS 9.2 was used to remove overlaps (all polygons with a specific SEDENV attribute value were combined using the Merge command, working from the topmost attribute layer the overlap was removed using the Clip command, and then the merged polygons were exploded to recreate the original individual polygons without overlaps) and extraneous "slivers."

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 source information was incomplete and had to be modified to meet the standard. 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.

SEDENV
Interpreted sea floor sedimentary environment
Scientist
Erosion or Nondeposition
High-energy environment within which sea-floor sediments are either removed or do not accumulate. Examples of features used to identify this sedimentary environment include: scour depressions, obstacle marks, and rocky outcrops in the multibeam bathymetry; high backscatter targets and areas of high backscatter in the sidescan sonar; gravel, boulders, and bedrock outcrops in the photography; and gravel in the sediment samples.
Scientist
Coarse Bedload Transport
Environment within which sea-floor sand and pea-gravel sized sediments are transported. Examples of features used to identify this sedimentary environment include: subaqueous dunes (i.e. sand waves and megaripples) in the multibeam bathymetry; moderate backscatter in the sidescan sonar; current rippled sand in the photography; and clean sand and fine gravel in the sediment samples.
Scientist
Sorting and Reworking
Environment within which sea-floor sediments are being separated into coarser and finer fractions. Examples of features used to identify this sedimentary environment include: relatively flat, featureless seabed in the multibeam bathymetry; areas of lower backscatter in the sidescan sonar; faintly rippled to undulating seabed and scattered shell accumulations in the photography; and fine-grained, slightly muddy sediment samples.
Scientist
Shapefile containing interpretations of sedimentary environments on the sea floor in Long Island Sound off the mouth of the Connecticut River. Shapefile shows distribution of environments characterized by erosion or nondeposition, coarse bedload transport, and sorting and reworking.
