A boomer seismic system was used to collect the subbottom data. Purpose: The purpose is to disseminate a digital version of a regional map showing the distribution of sub-bottom seismic profiles (boomer) collected in Fishers Island Sound and eastern Long Island Sound aboard the R/V ASTERIAS during 1990. The seismic data collected along these ship tracks can be used to provide useful information about the framework geology in this region.

This data set is the navigation from that cruise. Process_Step: Process_Description: Ten second navigation data was converted to an Info table and one record for every minute was selected from the set. These records were generated into an Arc coverage using the Lat/Long coordinates (provided by the LORAN C navigation system). The coverage was projected to CT state plane coordinates and compared to digital base maps. The entire set of points was moved (as a group) using ArcEdit to reflect the local variation in LORAN. Attributes were added.

The lat/lon coords from the original navigation system were deleted since they did not reflect the plotted position of the navigation points. A shapefile was generated using ArcView.
