Description:

Abstract:

This GIS layer contains the station navigation for the U.S. Army Corps of Engineers Coastal Engineering Research Center (CERC) cores collected in Long Island Sound. These cores were originally collected in 1967 as part of the Inner Continental Shelf Sediment and Structure (ICONS) program to appraise sand resources.

Purpose:

The purpose is to disseminate a digital version of a regional map showing the distribution of vibracores collected in Long Island Sound as part of the ICONS program of the USACOE. These cores can be used to provide useful information about the framework geology in this region.

Supplemental_Information:

When the USACOE ICONS program was active, each of the 18 project areas was stand-alone and covered sites on the East, West , and Gulf coasts and Great Lakes. The numbering system was the same throughout this program, but was restarted for each set of cores (e.g. those from Long Island Sound had their own set of IDs). Therefore each area had a core no. 1 and the core IDs increased numerically with that area. Andrew Grosz (USGS), who used the cores for a heavy-mineral assessment, wanted a more national perspective so he had a new, continuous set of numbers assigned to the approximately 1500 cores that George Burbank at Hampton University split and described (USGSID). Because not all of the cores collected from an area as part of the ICONS program were used in the CERC Technical Reports, some cores do not have data in the CERCID (originally 81_1ID) field.

Vibracores were collected as part of the USACOE's ICONS program. This dataset contains the locations of those cores collected in Long Island Sound.

Process_Step:

Process_Description:

80,000 scale mylar plots of the core locations (either provided by, or based upon the original navigation system plots) were registered and digitized (using a Calcomp 9100 table and PC Arc/Info) to create point coverages with CT state plane coordinates. Attributes (COREID and 81_1ID) for coreids were added.
