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, Coastal and Marine Geology Program, Woods Hole Science Center. 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 reserves, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30m 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/html/current_map.html>. This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. They were collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005. Seismic profile data, sediment samples and bottom photography were also collected in 2005.
Purpose:
The purpose of these data is to establish high-resolution acoustic depth measurements of the seafloor for regional geologic framework investigations. These data cover 257 square kilometers of the offshore survey area between Cape Ann and Salisbury Beach, Massachusetts, in depths between 7 m and 91m. The data were collected by Science Applications International Corporation (SAIC), in 2004 for the USGS, under contract to the University of New Hampshire.

Vertical_Positional_Accuracy_Report:
Vertical accuracy of <= to 0.5 meters for 95.8 percent of the soundings in water depths between 7-91 meters. These data were quantitatively compared by cross line junction analysis. 95.8 percent of the comparisons were within 50 cm (vertical) of each other. Ship motion (heave, pitch, yaw, roll) was recorded with a TSS POS/MV 320 Position and Orientation System. The NOAA tide station in Portland, ME 8418150 was the source of preliminary water level heights for Cape Ann to Salisbury Beach offshore survey area. Preliminary tide data for this station were downloaded from the NOAA CO-OPS web page http://www.co-ops.nos.noaa.gov/ hydro.html). All tide data were annotated with Coordinated Universal Time (UTC). The zoning parameters SAIC created were: On Portland, ME (8418150) + 8 minutes ratio 0.964 On Boston Light, MA (8444162) +2 minutes ratio 0.972 All bathymetry data collected during the survey were corrected for water level variations using water level files. Water level files for each tide zone were created from downloaded preliminary NOAA tide data using the Survey Analysis and area Based Editor (SABER) Create Water Level Files tool. Water level files contain water level heights that are subtracted algebraically from depths to correct the sounding for tide and water level. These water level files were applied to the multibeam data using the Apply Tides tool within the SABER software. Comparison of the zoned 6-minute water level heights computed from Boston Light, MA (8444162) to those computed from Portland, ME (8418150) shows an average height difference of 0.009 meters and a standard deviation of 0.042 meters. The maximum and minimum differences were +0.125 meters and -0.078 meters. Because the Portland, ME (8418150) gauge is a NOAA Primary Control Tide Station water level zoned heights from that station were used to correct the soundings. Sound velocity casts were taken every 2-4 hours with a Brooke Ocean Technology MVP 30 System and Applied Microsystems Smart Sound Velocity Sensor.

System Setup and Operation. The offshore bathymetric data were collected in 2004 using a hull-mounted RESON 8101 multibeam echo sounder operating at a frequency of 240 kHz. A cutoff angle of 57 degrees (114 degrees total swath width) was used for data collection. A TSS POS/MV Model 329 Position and Orientation System was used as the vessel's motion sensor. Sound velocity casts were taken every 2-4 hours with a Brooke Ocean Technology MVP 30 System and Applied Microsystems Smart Sound Velocity Sensor. The SAIC ISS2000 Integrated Survey System Software was used to monitor real-time data during the survey. A Trimble 4000 DGPS receiver was used for all navigation (SAIC, 2004). A patch test was conducted at the beginning of the survey in order to measure roll angle offsets. Roll angle offsets can have a strong effect on the accuracy of depth measurements. The roll angle offset is the difference between the motion sensor vertical measurement and the nominal mount angle of the transducers. The calculated roll angle offsets were stored within the SABER acquisition software.
Process_Step:
Process_Description:
The majority of the multibeam data were initially edited onboard the survey vessel, using SAIC's Multi View Editor (MVE) program. This tool is a geo-referenced editor, which allows for both plan and profile views with each beam in its true geographic position and depth. Each data file was edited to remove noise, fish, etc. At the end of each leg, both the raw and processed data were backed up onto 4mm tapes and shipped to the Data Processing Center in Newport, RI. Once the data were in Newport and had been extracted to local machines, track lines were created by extracting the sounder position from the multibeam data. The tracks were reviewed to confirm that no errors in navigation existed and that the tracks extended to the outermost bounds of the survey area. After the application of preliminary tides and interpolated draft, multibeam binned-depth grids were generated. A 5-meter Pure File Magic (PFM) grid was generated and edited in area based mode using MVE. The 5-meter projected PFM allowed multiple line editing which enhances visualization and proves efficient in the MVE process to ensure data quality. If any anomalies were found in the sounding bins, the edited multibeam files were re-examined and re-edited as necessary. When all multibeam files were determined to be satisfactory, the data were binned to a 5-meter and 2-meter cell size, populating the bin with the average of all soundings in the bin and maintaining the position of the center of the bin.

Process_Description:
USGS Grid Generation: The ASCII Raster file delivered by SAIC was produced with all survey lines including the main scheme, gap fill, and cross lines used for junction analysis. These cross lines are oriented at right angles to the main scheme (north-south) survey lines and extended shoreward into the nearshore survey area. These cross lines were not required for the final bathymetric grid. A new CARIS HIPS project (ver 6.1) was created with the projection information set to Universal Transverse Mercator (UTM) Zone 19, WGS84. The Processed GSF files for all main scheme lines were imported to CARIS using the import/conversion wizard A 5 meter Bathymetry and Statistical Error (BASE) surface was built from the line files. All previous edit flags were imported and no further editing was done in CARIS.

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. file had a source contribution, but no source citation information. This information was populated based on information in the source contribution. The distribution format was edited to AIG, based on information contained in the last original process step. AIG indicates Arc/Info Binary Grid. Other minor edits were probably performed (title, publisher, publication place, etc.). 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.

These data are available as a ArcInfo 32-bit floating point binary grid in Environmental Systems Research Institute (ESRI) format. The grid consists of two folders, one with the "grid name", and one "info" folder. The two folders for each grid are compressed into one file using WinZip (ver. 9.0) software. To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an ESRI ArcRaster grid. The two folders for each grid must be uncompressed to the same folder. If during the process of extracting multiple grids in WinZip format to the same folder, the user is prompted by WinZip software to "overwrite existing files" in the info folder select the "yes" option.
