Description:

Abstract:

This GIS layer contains the shiptrack navigation points 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. Attributes were added.

Process_Step:

Process_Description:

The navigation coverage was projected to Latitude/Longitude using Arc/Info. Decimal degree coordinates were ungenerated and joined to the attribute table as PLAT and PLON. 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.
