During 1975, the U.S. Geological Survey (USGS) conducted a seismic-reflection survey utilizing Uniboom seismics in eastern Rhode Island Sound aboard the Research Vessel Asterias. This cruise totalled 8 survey days. Data from this survey were recorded in analog form and archived at the USGS. Due to recent interest in the geology of Rhode Island Sound and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from this cruise were scanned and converted to TIFF images and SEG-Y data files. Navigation data were converted from LORAN-C time delays to latitudes and longitudes, which are available in ESRI shapefile format and as eastings and northings in space-delimited text format.
This GIS layer contains the ship-track navigation collected aboard the R/V Asterias during a 1975 geophysical cruise in eastern Rhode Island Sound. It contains navigation for the SEG-Y files created from analog records of data collected on the cruise. It is part of a digital version of a regional map showing the distribution of sub-bottom seismic profiles collected in Rhode Island Sound. The seismic data collected along these ship tracks can be used to provide useful information about the framework geology in this region. This data combined with the shot point navigation shapefile can be used to spatially correlate the SEG-Y and PNG files with other features in the GIS.

Attribute data were recorded by the science party and entered and checked by the compilers in a consistent manner.
The layers were edited and processed in a consistent manner.
Complete information is provided for all navigation lines in the data set and correspond to digitized SEG-Y files. Navigation points are spaced at 1-minute intervals and at course changes or line events (start/end of line). Continuous navigation is not available.
All navigation was done by LORAN-C and was manually recorded. The cruise used the Group Repetition Interval 9930 U.S. East Coast chain and recorded time delays from Cape Race, Newfoundland (X) and Dana, Ind. (Z) slave transmitters. Absolute accuracy is 185 to 463 m based on a link no longer available from http://www.navcen.uscg.gov/. The original link referred to the loran/handbook/h-book.htm (see Chapter III). A possible new link with similar information is available from: http://www.navcen.uscg.gov/pdf/loran/handbook/loran-c_users_handbook_entire.pdf.

LORAN-C navigation data were recorded during field work in eastern Rhode Island Sound. This data set contains the latitude and longitude coordinates converted from the LORAN-C time delays described in the a75_6nav_sort.shp metadata (http://pubs.usgs.gov/of/2009/1003/data/nav/eris/a75_6nav/a75_6nav.zip).
Used VAC Extras (v. 2.04) Points to Line v2 tool to create lines of the 1-minute navigation point shapefile that corresponds to the SEG-Y lines. The attribute "LineSeg" was used as the unique line identifier. Additionally, the tool allowed the attribute "LineID" to be brought over to the polyline shapefile.

Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Minor fixes to the attribute format for some attributes were needed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

This metadata was partially generated by importing an existing metadata file in text format. A known bug in ArcCatalog is that importing metadata can under certain circumstances scramble some attribute tags. All the attributes and their definitions are present, but the order of the attributes in the metadata does not match the order of the attributes in the attribute table.
