The U.S. Geological Survey (USGS) mapped approximately 336 square kilometers of the lower shoreface and inner-continental shelf offshore of Fire Island, New York in 2011 using interferometric sonar and high-resolution chirp seismic-reflection systems. These spatial data support research on the Quaternary evolution of the Fire Island coastal system and provide baseline information for research on coastal processes along southern Long Island. For more information about the WHCMSC Field Activity, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-005-FA.
This shapefile represents approximately 2800 kilometers of bathymetric trackline data collected with an interferometric sonar (Systems Engineering and Assessment Ltd. (SEA) SWATHplus-M (234 kHz)) by the U.S. Geological Survey during USGS field activity 2011-005-FA. The trackline data show the locations where bathymetric data were collected and are used to correlate bathymetric data with other geophysical data sets.

All trackline data (bathymetry and acoustic backscatter) data were collected during USGS field activity 2011-005-FA using an SEA SWATHplus 234-kHz interferometric sonar and a Coda Octopus F180R Attitude and Positioning System. Quality control was conducted during processing of the data; any spurious data were removed.
This shapefile contains all trackline navigation for the SEA SWATHplus 234-kHz interferometric sonar (bathymetry and acoustic backscatter). For completeness: Line 1 - 51, 61 - 64, 68 - 87, and 93 - 109 were used to generate the bathymetric grid and the acoustic backscatter mosaic. Lines 52-60, 65 - 67, and 89 - 92 are tie lines collected orthogonal to the shoreline. Tie lines were used to QA/QC the bathymetric data during data processing, but were not incorporated into the final bathymetric grid or acoustic backscatter mosaic. Lines l27f5, l28f1, l28f2, l29f4, and l61f1 were not included in the acoustic backscatter mosaic, as the raw data files, needed in order to extract acoustic backscatter, were not recorded. However, field processed bathymetric data for these lines were available and were incorporated in the final bathymetric grid.
Navigation was acquired with Differential Global Positioning System and Wide Area Augmentation System (DGPS+WAAS), which is accurate to + or - 1 to 2 meters, horizontally. The forward, or primary, Coda Octopus F180R Attitude and Positioning system antenna was used to acquire DGPS data and transmit via a network connection to the SEA SWATHplus data acquisition software. The F180R Attitude and Positioning system uses 2 L1 antennas for position and heading and an Inertial Measurement Unit (IMU) for motion sensing (heave, pitch, roll and yaw). The F180R IMU is mounted directly above the SEA SWATHplus-M transducers on the sidemount. The F180R antennas are mounted at the top of the sidemount offset in a forward/aft configuration. The offsets were applied within the SWATHplus and Coda Octopus F180R acquisition software.

Survey: Survey lines were run at an average speed of 5 knots. Lines 1 through 27 were run at a 75-m line spacing to achieve full coverage of the seafloor in a priority area of interest in the nearshore, in water depths less than 15 meters. Lines 28 through 109 were run at a 150-m line spacing, with the exception of tie lines (lines 52 through 60, 65 through 67, 89 through 92), which were run at approximately a 2-km line spacing.
Sonar: Swath-bathymetric and acoustic-backscatter data were acquired with a SEA, Ltd., SWATHplus-M interferometric sonar operating at a frequency of 234 kHz and a variable range (increased or decreased manually depending on water depth). The system was operated with a transmit power: 80 percent, 4096 samples per channel, and a variable range (increased or decreased manually depending on water depth). The SWATHplus-M was mounted on the port side of the M/V Scarlett Isabella during survey operations. A Coda Octopus F180R Attitude and Positioning system recorded ship motion (heave, pitch, roll, and yaw). These data were transmitted via network connection to the SWATHplus-M acquisition software. The Octopus F180R Inertial Measurement Unit (IMU) was mounted directly above the SEA SWATHplus-M transducers, to minimize lever arm offsets that can lead to positioning errors. The F180R uses two L1 antennas for position and heading accuracy. The antennas are mounted on a rigid horizontal pole, positioned at the top of the sidemount, with a horizontal separation of 1 meter and are offset from the IMU in a forward/aft configuration. The forward offset of the primary antenna from the IMU is 0.5 meters, with no port/starboard offset.
Sound Velocity Profiles: 135 sound velocity profiles were acquired during survey operations at roughly 1 to 3 hour intervals using an Odim Brooke Ocean MVP30 motion vessel profiler. The MVP30 failed during survey operations. Sound velocity profiles were only collected during JD140 through 149 (lines 1 through 47).
While much effort was devoted to cleaning the data and minimizing survey artifacts, some artifacts may still be seen in the final gridded data including an along track artifact at nadir (the ship track) and at the far edges of a survey line in areas where adjacent swaths overlap. These artifacts are especially noticeable in areas of little local relief.
Converting Raw (SXR) to Field-Processed (SXP) Files:
Raw SXR bathymetry data were acquired with the SEA SWATHplus acquisition software (version 3.07) and used to generate field-processed SEA SWATHplus SXP files.
Wayne E. Baldwin performed this and all subsequent process steps.

CARIS:
A new CARIS HIPS project (version 7.1) was created with projection information set to Universal Transverse Mercator (UTM) Zone 18N, WGS84. Each SWATHPlus processed file (sxp) was imported to the new CARIS project using the Import/Conversion Wizard. Navigation was reviewed and edited as needed using the Navigation Editor Tool. No additional navigation editing was required.
2011
Convert CARIS Tracklines to Shapefile:
The tracklines in the CARIS project were converted to an Esri polyline shapefile during a two-step process. 1) the CARIS tracklines were converted to a CARIS Map using the export tool within HIPS "HIPS to CARIS Map" Input File: All lines in the HIPS Project. The "Export Track Lines" option was checked. 2) using CARIS Conversion Utility (ver. 2.1) the CARIS Map (.des) file was converted to an Esri polyline shapefile. During the conversion the name of the HIPS line file and the year and Julian Day were carried over to the shapefile attributes.
2011
ArcGIS 9.3:
The polyline shapefile was checked to ensure there were no spurious navigation fixes. XTools Pro (version 7.1.0) was used to add Length_km field to the polyline shapefile's attribute table, specifying UTM Zone 18 N, WGS84 - kilometers. The Field Calculator was used to add and populate the following fields: Survey, Acq_Systerm and Ship.
The polyline shapefile was reprojected from UTM, Zone 18 N, WGS84 to Geographic Coordinate System (GCS), WGS84 using Data Management Tools, Projection and Transformations, Feature, Project tool.
2011
The online links to the data were updated to reflect the new server hosting the data. Additionally, other small edits could be made to the metadata, such as modifying http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes.
