  Description:
    Abstract: This GIS layer contains the shiptrack navigation lines collected aboard the RV ASTERIAS during a 1990 geophysical cruise to Fishers Island Sound and eastern Long Island Sound. 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.

      Source_Contribution: High-resolution seismic-reflection data were collected during field work conducted in Fishers Island Sound and eastern Long Island Sound during 1990.  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. Ungenerated point coordinates were used to  generate a line coverage. Lines were edited where  necessary (split at start/end) and attributes were added.
