This report presents maps of bathymetry, acoustic backscatter, the coastal plain unconformity, the Holocene marine transgressive surface and modern sediment thickness. 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. More information about this field activity and the data collected can be found at the Field Activity Web Page (http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-005-FA) Purpose: This GeoTIFF represents approximately 2800 line kilometers of acoustic backscatter data collected in 2011. These data were collected using an interferometric sonar (Systems Engineering and Assessment Ltd. (SEA) SWATHplus-M (234 kHz)) by the U.S. Geological Survey during USGS survey 2011-005-FA. Acoustic backscatter data were used to define the surficial sediment distribution on the inner-continental shelf offshore of Fire Island, New York to help assess environmental change caused by natural processes and human activities.

Image pixel values contain acoustic reflectivity values normalized to a 24-bit data range. Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). The background color is set to 0-0-0 and can be turned off without removing data values. Logical_Consistency_Report: This image represents interferometric acoustic backscatter data collected offshore of Fire Island, New York. Gaps generally occur along-track and between adjacent lines where complete coverage of the sea floor was not possible due to narrow swath widths. This primarily occurs in the shallowest regions of the survey. Completeness_Report: Line 1 - 51, 61 - 64, 68 - 87, and 93 - 109 were used to generate the GeoTIFF image. Lines 52-60, 65 - 67, and 89 - 92 are tie lines collected orthogonal to the shoreline. Lines l27f5, l28f1, l28f2, l29f4, and l61f1 were not included in the mosaic, as the raw data files were not recorded. Tie lines were not incorporated in the GeoTIFF image. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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.

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 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 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 GeoTIFF including an along track artifact at nadir (the ship track). These artifacts are especially noticeable in the shallow nearshore region of the survey. More information about this field activity and the data collected can be found at the Field Activity Web Page (http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-005-FA) Process_Step: Process_Description: Raw (SXR) : Raw SXR bathymetry and acoustic backscatter data were acquired with the SEA SWATHplus acquisition software (version 3.07). The SWATHplus acquisition software applies the pitch, roll, heave, yaw and heading data supplied by the Coda Octopus F180R IMU, to compensate for any ship motion. Jane F. Denny performed this and all subsequent process steps. Process_Date: 2014 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jane F.

The sonar data were processed to correct for towfish altitude (i.e. proper bottom tracking of the sea floor), and slant-range and beam pattern distortions inherent in the sonar data. Beam pattern distortions were minimized using an empirical gain normalization function. A composite mosaic was generated within SonarWiz, and exported as a 24-bit GeoTIFF image file, with no data values explicitly set to 0, 0, 0. Process_Date: 2014 Process_Step: Process_Description: Import to ArcGIS 9.3.1: The 24-bit GeoTIFF was added to an ArcGIS 9.3.1 map project. For best display, the image symbology was set to stretched, display background value 0, minimum-maximum stretch of 40 (low) to 120 (high). Process_Date: 2014 Process_Step: Process_Description: Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). All of the online links to the publication pages and data had to be fixed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
