Purpose: This data layer, which focuses on benthic communities, was developed as part of a cooperative project between the University of New Haven, the Connecticut DEP, and the U.S. Geological Survey. Benthic communities are an integral component of the ecology of LIS. Understanding the role that spatial heterogeneity plays in the dynamic of benthic landscapes may be a key to developing a better understanding of the estuarine ecology and the impacts of huuman activity. The purpose of providing this data layer is to help establish a regional framework for developing a more extensive GIS for benthic communities in LIS that can be used for education, research, and environmental management.

This survey was processed at 3,479-scale utilizing the U.S.G.S. Mini Image Processing system (MIPS) in an Equatorial Mercator Projection. Processing included bottom, ratio, and radiometric corrections; sectioning the survey area; "Geoming" individual map sections; "stenciling" and "mosaicing"; and building the final image. The shading convention for this mosaic is that dark tones are interpreted as fine sediment (fine sand, silt and clay); and light tones are interpreted as coarse sediment. Rough and "grainy" patches are interpreted as glacial drift or bedrock outcrops.The image files contained here have been modified, using Arc/Info software, from the three original TIFFs delivered by University of Rhode Island. The images were converted to grids, geo-referenced, and individually reclassified in a manner similar to linear stretching to account for variations in gray scales among the three sections of the mosaic. The grids were then converted back to TIFF format with world files in Latitude/Longitude decimal degrees (no projection). Pixel size is approximately 0.8 meters.

The interpretation (polygons) was drawn manually on paper from sediment point data. These polygons were digitized in ArcInfo and the resultant data were converted into a shape file.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. Additional small edits including (but not limited to) such as adding the edition element, fixing browse graphic information etc. were perfomed on the metadata. Author names were edited to remove "ed." and "comp". Added links to access the data including the DOI link. Added USGS Thesaurus keywords. Added keywords section with USGS persistent identifier as theme keyword (PID). Fixed the ellipsoid name to agree with the datum. Fixed the denominator of flattening ratio. The SED_TYPE attribute was updated to be an enumerated domain specifying the specific values. The definition was based on information in Chapter 10 of the Larger Work citation. The units defined in the figure were compared to the shapefile with the map legend definition applied in the attribute value. Updated the distribution liability. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. A generic email in the metadata contact was used, along with adding contact instructions. These edits are not all the edits performed. Additional small edits such as adding the edition element as well as other edits were performed. 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.
