The objective of the study is to better understand barrier-island geomorphic evolution, particularly storm-related depositional and erosional processes that shape the islands over annual to interannual timescales (1‒5 years). Collecting geophysical data will allow us to identify relationships between the geologic history of the island and its present day morphology and sediment distribution. This mapping effort was the third in a series of three planned surveys in this area. High resolution geophysical data collected in each of three consecutive years along this rapidly changing barrier island system will provide a unique time-series dataset that will significantly further the analyses and geomorphological interpretations of this and other coastal systems, improving our understanding of coastal response and evolution over short time scales (1‒5 years). This data series includes the geophysical data that were collected during two cruises (USGS Field Activity Numbers (FAN) 13BIM02, 13BIM03, and 13BIM04, in July 2013; and FANs 13BIM07 and 13BIM08 in August 2013) aboard the R/V Sallenger, the R/V Jabba Jaw, and the R/V Shark along the northern portion of the Chandeleur Islands, Breton National Wildlife Refuge, Louisiana. Primary data were acquired with the following equipment: (1) a Systems Engineering and Assessment, Ltd., SWATHplus interferometric sonar (468 kilohertz [kHz]), (2) an EdgeTech 424 (424 kHz) chirp sub-bottom profiling system, and (3) two Teledyne Odom Hydrographic Systems, Incorporated, Echotrach CV100 single beam echosounders. This data series report serves as an archive of processed interferometric swath and single-beam bathymetry data. Geographic information system data products include an interpolated digital elevation model, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata.

Logical_Consistency_Report: This zip archive contains the single-beam bathymetry survey tracklines, recorded at the time of data collection for USGS cruises 13BIM03, 13BIM04 and 13BIM08. Field logs, vessel platform descriptions, and other survey information are available at, https://doi.org/10.3133/ds1032. Completeness_Report: This is a complete survey trackline dataset for the single-beam bathymetry data collected during USGS Cruises 13BIM03 and 13BIM04 in July 2013 and 13BIM08 in August 2013 from the southern Chandeleur Islands. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: For the July surveys, real-time kinematic (RTK) GPS was implemented in order to eliminate having to post-process the navigation component. Both base stations were equipped with a Magellan ProFlex500 GPS receiver, a Thales choke ring antenna, a Pacific Crest ADLP-1 390-430 megahertz (MHz) radio, and a Pacific Crest 5 decibel (dB) high power radio whip antenna. The radio whip antennas were placed onto 10-m collapsible masts providing line of site transmission to the vessels (rovers) anywhere within the survey boundary. The GPS and radio components were duplicated on each vessel. The base stations were set to record internally at a rate greater than or equal to the recording rate of the rovers, in this case 5 Hz. The known coordinates of each base station were entered into the GPS receiver and the RTK corrections were broadcast to the roving GPS receivers via the radio links at 5 Hz. The R/V Jabba Jaw recorded GPS positions at 1 Hz using an Ashtech Z-Xtreme GPS receiver. The R/V Shark recorded GPS positions at a rate of 5 Hz using a Magellan ProFlex 800 GPS receiver and Ashtech marine antenna. The manufacturer's stated accuracy of fixed RTK GPS data is 1 centimeter (cm) in the horizontal and 2 cm in the vertical. The raw trackline position data were recorded using HYPACK version 10 marine surveying, positioning, and navigation software. For the August surveys, RTK was not used due to time constraints and navigation data was post processed. The same base stations were used (TMRK and BRM2). The base receivers and the rover receiver recorded their positions concurrently at 1-second (s) intervals throughout the survey. GPS data was acquired and processed in the World Geodetic Datum of 1984 (WGS84) (G1150). The manufacturer's stated accuracy of the processed kinematic GPS data is 10 millimeters (mm) in the horizontal to 20 mm in the vertical. The raw trackline position data were recorded using HYPACK version 10 marine surveying, positioning, and navigation software. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The survey tracklines do not include or represent vertical data. Lineage: Process_Step: Process_Description: The trackline positions for USGS Cruise 13BIM03 and 13BIM04 were acquired on the vessels using an Ashtech Z-Xtreme GPS receivers for 13BIM03 and 13BIM08. An Ashtech Proflex 800 GPS receiver was used for 13BIM04. The raw trackline position data for all USGS FANs were recorded using HYPACK version 10 marine surveying, positioning, and navigation software.

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 trackline shapefiles files were then merged into one shapefile with a FAN attributes to differentiate the surveys. The resultant polyline shapefile was then projected in WGS84 Universal Transverse Mercator (UTM) Zone 16 North.
