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 (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. 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/). This is the spatial dataset for the Red Brook Harbor survey area within Buzzards Bay, Massachusetts. These data are the results of a high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples and bottom photographs) survey, conducted in 2009. In addition to inclusion within the USGS-CZM geologic mapping effort, these Red Brook Harbor data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system. (http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-018-FA) Purpose: This grid represents approximately 7 square kilometers of bathymetric data that were collected in Red Brook Harbor, Massachusetts, by the U.S. Geological Survey in 2009 as part of USGS survey 09018. Data were collected with a Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar system. These data are used to define the sea-floor morphology as part of the Massachusetts Sea-floor Mapping Project. The cell size for this grid is 1-meter by 1-meter.

Edition: 1.0 Series_Information: Series_Name: http://pubs.usgs.gov/of/2009/1072/ Issue_Identification: 2009-1072 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2009/1072/ Data_Quality_Information: Logical_Consistency_Report: This grid was interpolated to close data gaps that occurred along-track at nadir, and between adjacent lines. Completeness_Report: All quality main survey line bathymetric data that were collected within the Red Brook Harbor survey area were incorporated in this grid. Soundings were processed and edited using Computer Aided Resource Information System (CARIS) Hydrographic Information Processing System (HIPS; ver. 6.1). Although the soundings were manually edited, small data spikes may exist at outer edges of some swaths. In addition, small gaps between adjacent survey lines may exist in the shallowest areas of the survey. Tielines were used to verify tide corrections during post-processing, but were not used in generating this grid. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The SWATHplus transducers were mounted on a rigid, vertical pole, at the bow of the R/V Rafael, approximately 0.5 meters below the water line. Navigation antennas (one Differential Global Positioning System (DGPS) antenna and two Real-Time Kinematic (RTK) GPS antennas) were mounted on a horizontal crossbar atop the vertical transducer mount pole. The horizontal positions for soundings were acquired with an Octopus F180 Attitude and Positioning System integrated with a Novatel DGPS. Horizontal sounding positions were recorded to raw sonar data files (SXR) via SWATHplus acquisition software (version 3.06.05.00). Position data from an Ashtech Surveyor RTK GPS, a Novatel DL-V3 RTK GPS, and a CSI LGBX Pro DGPS were recorded by HYPACK survey software to HYPACK raw files. A conservative estimate of the positional accuracy of the CSI LGBX Pro DGPS unit is ± 2 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The manufacturer specifications for the SWATHplus interferometric sonar system indicate the vertical accuracy of data collected is approximately 1% of the water depth. In the Red Brook Harbor survey area, 1% of the water depth translates to a vertical accuracy range of 0 to 0.11 meters. RTK GPS was used to establish water-level heights relative to Mean Lower Low Water (MLLW) at decimeter-scale accuracies. Tide-correction was performed in post-processing (see process steps). Refraction artifacts were minimized by acquiring sound velocity profiles throughout the survey area to correct vertical offsets to soundings resulting from variations in the speed of sound within the water column. Daily changes in vessel draft due to fuel and water usage were not considered. Based on acquisition sensor accuracy, tide correction, and correction for speed of sound variability in the water column, it is estimated that the overall vertical accuracy of these bathymetric data is approximately 0.5 meters. Lineage: Process_Step: Process_Description: Each raw SWATHplus bathymetric sonar file (SXR) was converted to a SWATHplus processed file (SXP) using SEA SWATHplus Swath Processor (ver. 3.06.05.0). During the conversion process, sound velocity profiles were used to minimize potential refraction artifacts from fluctuations in the speed of sound within the water column. Various bathymetric filters were applied to eliminate sounding outliers.

Depths were corrected to Mean Lower Low Water (MLLW) using 1-second RTK GPS heights from the Ashtech RTK GPS receiver mounted over the SWATHplus sonar head. These heights were extracted from each HYPACK navigation file using the AWK (version 3.1.6) script "doRTK1_by_line_FIX." ASCII text files for each survey day were compiled and reformatted to CARIS Tides format (yyyy/mm/dd hh:mm:ss t.ttt).

Each SWATHplus processed file (SXP) was imported to the new CARIS project using the Import/Conversion Wizard. RTK tide files (prepared in previous processing step) were applied to all survey lines. Corrected tides were smoothed with a 1-minute moving-average in CARIS attitude editor. Navigation was edited as needed using the navigation editor tool in CARIS. A Bathymetric and Statistical Error (BASE) Surface was created at 1 meter cell size and was reviewed for any inconsistencies or data anomalies. Filters were applied to each line including beam to beam slopes and across track angle. The CARIS refraction editor was used to adjust the speed of sound in cases where the velocimeter did not provide adequate correction to flatten out the depth profiles produced by localized variations in speed of sound through the water column. Areas of overlap between the outer beams and the nadir gap of adjacent lines were manually edited extensively throughout the survey area. A final BASE surface was created at 1 meter and reviewed. A final 1 meter cell BASE surface was interpolated with a 5x5 matrix. The final 1 meter cell BASE surface was exported to ASCII format.

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.). Fixed URL in abstract. The distribution format name 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.

To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an ESRI grid. The two folders for each grid must be uncompressed to the same folder. Extracting grids from different publications into the same folder is not recommended and will likely render some of your grids unusable.
