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.

Attribute_Accuracy:
Attribute_Accuracy_Report:
All attribute data were recorded by the chief scientist and entered and checked by the compilers in a consistent manner.
Logical_Consistency_Report:
No additional checks for topological consistency were performed on this data set.
Completeness_Report:
Complete information is provided for all navigation points in the data set.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation was done by Loran C. Typical Loran accuracy for LIS is about 100 m.
Vibra cores were colected as part of a cooperative program between MMS and New England coastal states. This dataset contains the locations of those cores collected in Long Island Sound.
Process_Step:
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.
The navigation coverage was projected to Latitude/Longitude using Arc/Info. Decimal degree coordinates were ungenerated and joined to the attribute table. A shapefile was generated using ArcView.
