Bathymetric data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2013, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see . Purpose: The purpose of these data are to provide the navigation for USGS cruise 2013-005-FA as recorded by CSI LGBX Pro Differential Global Positioning System (DGPS) with HYPACK software. This provides an archive of the original navigation as well as allowing others to reprocess the navigation for their purposes.

Completeness_Report: These files represent all the navigation recorded by the HYPACK software version 11.1.6.24 during USGS cruise 2013-005-FA. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The navigation receiver used was a CSI LGBX Pro DGPS2. The accuracy of this system is better than 10 meters. Lineage: Process_Step: Process_Description: A USB thumb drive was used to transfer the text navigation files from the computer running the HYPACK navigation software. The original HYPACK navigation files are stored in a single folder. The filenames are in the format of linenumber_starttime.julianday. Since we weren't surveying any previously loaded lines, the "linenumber" is always 000. An example filename is 000_1214.202 which reflects line 000, start time 1214 and Julian day 202. The times in the filename reflect UTC (Coordinate Universal Time) times.
