Description:

Abstract:

This GIS layer contains an computer generated model of the distribution of surficial sediments in Long Island Sound.

Purpose:

The purpose is to disseminate a digital version of a regional map showing the distribution of surficial sediments in Long Island Sound. Grain size is the most basic attribute of sediment texture, and texture controls many benthic ecological and chemical processes.

Source_Contribution:

During field work conducted in Long Island Sound during June 1992 and March 1998, a total of 1,554 samples were collected. These samples were placed in sealed containers aboard ship and frozen for later grain-size analysis.

Process_Step:

Process_Description:

Samples for grain-size analysis were disaggregated and wet seived to separate the coarse and fine fractions. The fine fraction was analyzed by Coulter Counters. The coarse fraction was analyzed by sieving and a rapid sediment analyzer. Bivalve shells and other biogenic carbonate debris were manually removed from the gravel fraction before analysis. All textural data were salt corrected.

Process_Description:

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 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 Texture attribute was updated to be an enumerated domain specifying the specific values. The definition was based on information in Chapter 4 of the Larger Work citation, particularly Figure 3. 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. 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. (20230626)

Overview_Description:

Entity_and_Attribute_Overview:

This datalayer (the texture of surficial sediments in LIS) provides information on sedimentary environment and aggregate resource potential. The Texture attribute was originally defined as text, and later edited to add the enumerated domain values (20230616) based on the information in Chapter 4 of the Larger Work Citation - primarily used Figure 3 in that chapter.
