The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico, specifically Grand Bay AL/MS and Vermilion Bay, Louisiana, as well as along the US east coast in Chincoteague Bay Virginia/Maryland. The data included in this data release will provide baseline bathymetric information for future research investigating wetland/marsh evolution, sediment transport, recent and long term geomorphic change, and will support modeling of future changes in response to restoration and storm impacts. The survey area encompasses more than 40 square kilometers (km2) of Grand Bay’s incorporated waters. This data release archives processed single-beam bathymetry data, collected from May 28-June 3, 2015 (USGS Field Activity Number [FAN] 2015-315-FA). Geographic information system (GIS) data products include: a 10 and 30-meter cell size interpolated bathymetry grid, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System (FACS) logs, and formal Federal Geographic Data Committee (FGDC) metadata. Purpose: This zip file, Grand_Bay_2015_SBB_tracklines.zip, contains Esri trackline vector files for all single-beam bathymetry data collected from May 28-June 3, 2015 under FAN 2015-315-FA, which encompasses data from two separate survey platforms; the RV Shark (15CCT04), and RV Chum (15CCT05), during the Grand Bay Alabama/Mississippi Survey. Additional survey details are available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-315-FA. Supplemental_Information: Trackline files were recorded at time of the survey using HYPACK version 13.0.09.17 (15CCT04, 15CCCT05) marine surveying, positioning, and navigation software. Within this document all platforms will be distinguished by FAN (15CCT04-RV Shark, 15CCT05-RV Chum) as separate but similar entities as all data are acquired, processed and presented as a whole.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: An Ashtech Global Positioning System (GPS) receiver on all survey platforms recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via Global Navigation Satellite Systems (GNSS) antenna. The manufacturer's stated accuracy of the post processed kinematic GPS data is +/- 1 centimeter (cm) in the Horizontal plane.

Lineage: Process_Step: Process_Description: Acquisition: The trackline positions for USGS FAN 2015-317-FA were acquired using Ashtech Proflex GPS receiver units streaming position data to the hydrographic software, HYPACK®, a marine surveying, positioning, and navigation software package that managed planned line information and provided real-time navigation, steering, correction, data quality, and instrumentation-status information to the boat operator (HYPACK® version 13.0.09.17). Both platforms were equipped with Ashtech Proflex GPS receivers recording 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via Ashtech Global Navigation Satellite Systems (GNSS) antennas. All navigation information was saved into a single raw data file (.raw) in HYPACK®, with each device string referenced by a device identification code and time stamped to Coordinated Universal Time (UTC).

The trackline shapefile was created from the x,y,z point data shapefile, using the XTools' feature conversion tool, "make polylines from points". Within XTools' feature conversion selection window, the following items were selected. The "group by field selection" was set to use the HYPACK line name attribute and the "input feature order - order by field" was set to use the FID attribute. The resultant polyline shapefile was then projected in WGS84 Universal Transverse Mercator (UTM) Zone 16 North.
