Description:

Abstract:

This GIS layer contains the shiptrack navigation collected aboard the R/V ASTERIAS during a 1981 geophysical curise to Block Island Sound and easternmost Long Island Sound.

Purpose:

The purpose is to disseminate a digital version of a regional map showing the distribution of sub-bottom seismic profiles (boomer) collected in Block Island Sound and easternmost Long Island Sound. The seismic data collected along these ship tracks can be used to provide useful information about the framework geology in this region.

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 lines in the data set. Navigation points are spaced at 5 minute intervals (approx) and at course changes or line events (start/end). Continous navigation is not available.
