Fredericks Thomas M. Tuten 2017 multimedia presentation U.S. Geological Survey Data Series 1041 St. Petersburg, Florida U.S. Geological Survey https://doi.org/10.3133/ds1041 As part of the Barrier Island Comprehensive Monitoring Program (BICM), scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore single-beam bathymetry survey along the south-central coast of Louisiana, from Raccoon Point to Point Au Fer Island, in July 2015. The goal of the BICM program is to provide long-term data on Louisiana’s coastline and use this data to plan, design, evaluate, and maintain current and future barrier island restoration projects. The data described in this report will provide baseline bathymetric information for future research investigating island evolution, sediment transport, and 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 300 square kilometers (km2) of nearshore environment from Raccoon Point to Point Au Fer Island. This data series serves as an archive of processed single-beam bathymetry data, collected from July 22–29, 2015, under USGS Field Activity Number 2015-320-FA. Geographic information system data products include a 200-meter-cell-size interpolated bathymetry grid, trackline maps, and point data files. This zip file contains ESRI trackline vector files for all single-beam bathymetry data collected from July 22-29, 2015 under Field Activity Number (FAN) (2015-320-FA), which encompasses data from four separate survey platforms; the R/V Sallenger (15BIM05), R/V Jabba Jaw (15BIM06), R/V Shark (15BIM07), and R/V Chum (15BIM08) apart of the July 2015 Point Au Fer Survey. Trackline files were recorded at the time of the survey using HYPACK version 14.0.9.47 (15BIM05, 15BIM06) and 13.0.09.17 (15BIM07, 15BIM08) marine surveying, positioning, and navigation software. Within this document, all platforms will be distinguished by FAN (15BIM05-R/V Sallenger, 15BIM06-R/V Jabba Jaw, 15BIM07-R/V Shark, 15BIM08-R/V Chum) as separate but similar entities. 20150722 20150729 ground condition Complete None planned -91.393536 -90.843381 29.333493 29.055930 USGS Metadata Identifier USGS:09aab08c-c08f-44ef-8404-de00d54a6593 ISO 19115 Topic Category geoscientificInformation location imageryBaseMapsEarthCover oceans USGS Thesaurus marine geology geophysics bathymetry None tracklines hydrography geophysical single-beam bathymetry HYPACK U.S. Geological Survey USGS St. Petersburg Coastal and Marine Science Center SPCMSC Coastal and Marine Geology Program CMGP Barrier Island Comprehensive Monitoring Program Barrier Island Mapping 15BIM05 15BIM06 15BIM07 15BIM08 2015-320-FA Geographic Names Information System (GNIS) Louisiana Gulf of Mexico Point Au Fer Raccoon Point Atchafalaya Bay Atchafalaya River None datum water shoreline None July 2015 none The U.S. Geological Survey requests that it be referenced as the originator of this dataset in any future products or research derived from these data.

St. Petersburg FL 33701 USA (727) 502-8000 cstalk@usgs.gov U.S. Geological Survey, Coastal and Marine Geology Program (SPCMSC), St. Petersburg Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.2.2.3552 No formal attribute accuracy tests were performed. These datasets are from one field activity with consistent instrument calibrations This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. An Ashtech GPS receiver on all survey platforms recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via a Thales choke-ring antenna (15BIM05,15BIM06) and from smaller Global Ashtech Global Navigation Satellite Systems (GNSS) antennas (15BIM07, 15BM08). The manufacturer's stated accuracy of the post processed kinematic GPS data is +/- 1 centimeter (cm) in the Horizontal plane. The survey tracklines do not include or represent vertical data. Acquisition: The trackline positions for USGS Cruise 2015-320-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 14.0.9.47 for 15BIM05, 15BIM06 and version 13.0.09.17 for 15BIM07, 15BIM08 respectively). All platforms were equipped with Ashtech Proflex GPS receivers recording 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via Thales Choke-ring antennas (15BIM05, 15BIM06) and smaller Ashtech Global Navigation Satellite Systems (GNSS) (15BIM07, 15BIM08). 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). 2015 Cherokee Nation Technologies/U.S. Geological Survey Chelsea A.

St. Petersburg FL 33701 U.S. (727) 502-8000 cstalk@usgs.gov Processing/Shapefile creation: The trackline vector file was created in Esri ArcGIS version 10.2.2.3552 using the XTools Pro extension, version 11.0 build 1328. 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 15 North. 15BIM05_SBB_Level_03_1041_ITRF00_shape.shp 15BIM06_SBB_Level_03_1041_ITRF00_shape.shp 15BIM07_SBB_Level_03_1041_ITRF00_shape.shp 15BIM08_SBB_Level_03_1041_ITRF00_shape.shp 2015 15BIM05_SBB_tracklines.shp 15BIM06_SBB_tracklines.shp 15BIM07_SBB_tracklines.shp 15BIM08_SBB_tracklines.shp Cherokee Nation Technologies/U.S. Geological Survey Chelsea A.
