A boomer seismic system was used to collect the subbottom data. The purpose is to disseminate a digital version of a regional map showing the distribution of sub-bottom seismic profiles (boomer) collected in eastern Long Island Sound aboard the R/V ASTERIAS during 1982. The seismic data collected along these ship tracks can be used to provide useful information about the framework geology in this region.

No additional checks for topological consistency were performed on this data set. Complete information is provided for all navigation points in the data set with the following excepts - loran numbers are not provided for the points in Block Island Sound, comments are not provided for the points in Long Island Sound. Navigation points are spaced at 5 minute intervals (approx) and at course changes or line events(start/end). Continous navigation is not available. All navigation was done by Loran C. Typical Loran. Accuracy for LIS is about 100 m. 100 Typical positioning accuracy of Loran C is +- 100 meters.

This data set is the navigation from that cruise. Selected 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.
