Why was the data set created?

This GIS 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.

How was the data set created?

  1. From what previous works were the data drawn?
    McCall, 1975 (source 1 of 1)

  2. How were the data generated, processed, and modified?
    Date: Unknown (process 1 of 3)
    Sediment samples were collected by grab sampler and were wet sieved to remove the mud fraction. Coarse fractions were stored in formalin until individual species specimens could be identified and counted with a binocular microscope under reflected light. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.50 flagged. 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. 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. 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.
