Description:

Abstract:

This GIS layer contains the shiptrack navigation collected aboard the RV ASTERIAS during a 1981 geophysical cruise 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.

Source_Contribution:

During field work conducted in Block Island Sound during September 1981 high-resolution seismic-reflection and LORAN-C navigattion data were collected. This data set is the 5-min. navigation from that cruise.

Process_Step:

Process_Description:

Five-minute navigation from the original Northstar-6000 printouts generated onboard the ASTERIAS were converted to decimal degrees and entered into a digital file.
