  Description:
    Abstract: This GIS layer contains the station navigation for vibracores collected in Long Island Sound during 1988. These cores were originally collected to study nearshore geologic framework.
    Purpose: The purpose is to disseminate a digital version of a regional map showing the distribution of vibracores collected during 1988 in Long Island Sound aboard the Atlantic Twin as part of a cooperative between New England coastal states and the Minerals Management Service. These cores, which were used to verify interpretations of high-resolution seismic-reflection profiles, can be used to provide useful information about the framework geology in this region.

      Process_Description: Navigation points from the original onboard logs were hand plotted on charts with Loran overlays. These overlays were then registered and digitized (using a Calcomp 9100 table and PC Arc/Info) to create point coverages with CT state plane coordinates. Attributes were added.
