Description:
Abstract:
These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 3-30 meters deep. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The data collected in the study area located in Northern Cape Cod Bay Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection), and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during five separate surveys conducted between 2006 and 2008 and cover 480 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the northern Cape Cod Bay project can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpage: 06012: http://quashnet.er.usgs.gov/data/2006/06012/ 07001: http://quashnet.er.usgs.gov/data/2007/07001/ 07002: http://quashnet.er.usgs.gov/data/2007/07002/ 07003: http://quashnet.er.usgs.gov/data/2007/07003/ 08002: http://quashnet.er.usgs.gov/data/2008/08002/
Purpose:
The purpose of this GeoTIFF is to publish single mosaic of acoustic backscatter of the seafloor acquired during four surveys using a Klein 3000 sidescan-sonar in the Cape Cod Bay survey area.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values).
Logical_Consistency_Report:
All sidescan-sonar data in this mosaic were collected with a Klein 3000 dual-frequency (132/445 kHz) sidescan-sonar system. Only the 132-kHz data were used to generate the sidescan-sonar mosaic. All data were processed with the same methods.
Completeness_Report:
This mosaic does not include all acoustic backscatter data collected in the northern Cape Cod Bay survey area. Data collected along transit lines, east-west seismic tie lines and other lines of poor quality were excluded from this mosaic The "mosaic" attribute in the CCB_BackscatterTracklines shapefile published in this report identifies the 626 lines that were included, and the 17 lines that were not included, in this mosaic. A data gap exists in this mosaic where the Klein sidescan winch was inoperable for one day. The backscatter data in this gap is covered by backscatter data acquired with the SEA Ltd. SWATHplus interferometric sonar (CCB_SwathBS_1m.tif).
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Field activities 06012 and 07002: The Klein 3000 towfish was deployed from the stern A-frame of the R/V Megan T. Miller. Real-time kinematic (RTK) GPS navigation data were provided by an Ashtech Z-Extreme receiver (an Ashtech BR2G DGPS was used as a backup system) and recorded to the raw data files (XTF) via the Klein SonarPro (version 9.6 & 10.0) acquisition software. During some portions of the survey, technical difficulties caused the GPS systems to malfunction and loose the "fixed" RTK signal. When this occurred, the navigation system generally defaulted to a "float" RTK or DGPS signal, or the navigation was lost. When possible, surveying was halted until a reliable GPS signal was restored. A digital cable counter attached to the winch used to deploy the sidescan-sonar towfish measured changes in the amount of cable extended from the A-frame and updated the cable out parameter in SonarPro. Using the cable out value and linear offset between the A-frame and the RTK-GPS antenna, Sonar Pro calculated towfish layback positions in real time and recorded them to the XTF file headers. A conservative estimate of positional accuracy is ± 10 m, but when the navigation system was providing the "fixed" RTK signal, positional accuracy is likely < 1 m. Positional uncertainty arises because layback calculations do not account for fish motion behind the vessel, which is caused by sea state and vessel speed induced changes in the angle and scope of the tow cable. Field activities 07001 and 08002: The Klein 3000 towfish was deployed from a davit on the port side aft on the R/V Rafael. Real-time kinematic (RTK) GPS navigation data were provided by an Ashtech Z-Surveyor Extreme receiver and recorded to the raw data files (XTF) via the Klein SonarPro (version 9.6 and 10.0) acquisition software. A conservative estimate of positional accuracy is ± 10 m, but when the navigation system was providing the "fixed" RTK signal, positional accuracy is likely <1 m.

Acoustic backscatter data acquisition for field activities 06012 and 07002: The Klein 3000 towfish was deployed from the stern A-frame of the R/V Megan T. Miller. A digital cable counter attached to the winch used to deploy the sidescan-sonar towfish measured changes in the amount of cable extended from the A-frame and updated the "cable out" parameter in SonarPro acquisition software (version 9.6). Backscatter data were collected with a 100 or 150 m range (200 or 300 m either side of towfish) depending on line spacing. Acoustic backscatter data acquisition for field activities 07001 and 08002: The Klein 3000 towfish was deployed from a davit on the port side of the R/V Rafael approximately 1 m astern and 0.5 m below the water surface. These data were acquired using a 75-100 m range(150-200 m total width).

Process_Description:
Within XSonar/ShowImage sidescan-sonar processing software (version: 1.1) a median filtering routine (4 pixels across track by 3 pixels along track) was applied to the raw sidescan-sonar data (XTF) to remove speckle noise. Processed data are stored as 8-bit data files. Navigation was also extracted from the raw data at a 1-minute interval and saved in ASCII format. Quality checks were conducted on the navigation to eliminate spurious or duplicate navigation fixes. The sonar data were further processed to correct for towfish altitude (i.e. proper tracking of the seafloor), and slant-range and beam pattern distortions inherent in the sonar data. Processed sonar files were then merged with the edited navigation then mapped at a 1.0 meter resolution in UTM coordinates (UTM, Zone 19N, WGS84, meters) and saved in two XSonar/ShowImage mosaic files (*.ras) representing odd and even (i.e. every other line) sonar tracklines. Processing occurred in 2006, 2007, and 2008.

PCI Mosaic: A new PCI project (ver.10.1.3) and four associated pix (06012.pix, 07001.pix, 07002.pix, 08002.pix) files were created to mosaic the TIFF files from each of the four surveys. Each TIFF file was imported to the corresponding pix file using the OrthoEngine module. Ground control points (GCPs) for each line were identified from adjacent overlapping lines. Once GCPs were collected, each line was orthorectified to the master pix file that is referenced to the Universal Transverse Mercator coordinate system (UTM) Zone 19 WGS84. All GCPs were saved to text files with RMS errors for each point.

Process_Description:
Final Mosaic: The four separate mosaics in pix format were combined into a new pix file (CCB_Klein_bs_1m.pix) that covered the entire extent of all four surveys in northern Cape Cod Bay using the basic steps below: 1) The rectified mosaic (*.pix) files from 07001 and 08002 were added to the new mosaic. 2) The rectified mosaic (*.pix) files for 06012 and 07002 were mosaiced together in PCI (CCB_offshore.pix) and then exported to a GeoTIFF (CCB_offshore.tif). The 8-bit range of the image (color stretch) was adjusted to visually match the inshore backscatter data in CCB_Klein_bs_1m.pix. 3) The color adjusted GeoTIFF (CCB_offshore_Adj.tif) was imported back into PCI and mosaicked into the CCB_Klein_bs_1m.pix file to generate a 1-m mosaic of Klein data. 4) The final mosaic (CCB_Klein_bs_1m.pix) was exported to a GeoTIFF (CCB_Klein_bs_1m.tif). A TIFF world file (tfw) was generated for the GeoTIFF using GeoTIFFExaminer (no version).

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). The format of the time period of content and some process dates had to be fixed. This file had a source contribution, but no other source information. This information had to be modified to meet the standard. The distribution format was modified in an attempt to be more consistent with other metadata files of the same data format. 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.
