The overall objectives of the study are 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). Collection of 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 first 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 report serves as an archive of processed interferometric swath and single-beam bathymetry data that were collected during two cruises (USGS Field Activity Numbers 11BIM01 and 11BIM02) along the northern portion of the Chandeleur Islands, Breton National Wildlife Refuge, Louisiana, in June of 2011. Geographic information system data products include a 50 m-cell-size interpolated bathymetry grid surface, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata. Purpose: This zip archive contains the survey tracklines in ESRI shapefile format for the interferometric swath bathymetry data collected in June 2011 around the northern Chandeleur Islands, Louisiana. Supplemental_Information: Trackline files were recorded at the time of the survey using HYPACK version 10 marine surveying, positioning, and navigation software.

The tracklines represent the data coverage extent for the interferometric swath bathymetry survey. These trackline data have not been independently verified for accuracy. Logical_Consistency_Report: This zip archive contains the interferometric swath bathymetry survey tracklines, recorded at the time of data collection in June 2011. Refer to the online data series linkage for field logs, vessel platform descriptions, and other survey information. Completeness_Report: This is a complete survey trackline dataset for the interferometric swath bathymetry data collected in June 2011 from around the northern Chandeleur Islands. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: An Ashtech GPS receiver on the survey boat recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via a Thales choke-ring antenna. The manufacturer's stated accuracy of the raw kinematic GPS data is 3 to 5 cenitmeters (cm). The raw trackline position data were recorded in 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.
