Edition: 1.0 Series_Information: Series_Name: Open-File Report Issue_Identification: 2007-1373 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2007/1373/ 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. 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 69 square kilometers of the near shore survey area between Cape Ann and Salisbury Beach, Massachusetts, in depths between 2m and 30m.

Completeness_Report: Soundings were processed and edited using CARIS 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 depth less than 14 meters. Swath bathymetry was collected along additional offshore tie-lines for use with the seismic profiles and for cross-track depth comparison. Bathymetric data collected on these offshore tie lines are not included in this grid. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were navigated using Real-Time Kinematic Global Positioning System (RTK-GPS) which provides horizontal positional accuracies (x and y) on the decimeter scale (http://www.noaa.gov; http://www.nos.noaa.gov; http://www.ngs.noaa.gov). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical accuracy of the acquisition system may approximate 1% of water depth, 0.1-0.3 meters within the survey area. However, overall vertical accuracies of <= 0.5 m are assumed based on the following considerations. Ship motion was recorded with a TSS DMS 2-05 and used to correct for heave, pitch, roll and yaw. RTK-GPS was used to establish water-level heights relative to Mean Lower Low Water (MLLW), providing decimeter-scale accuracies. Refraction artifacts were minimized by acquiring a range of sound velocity profiles throughout the survey area to model the sound velocity structure of the water column. Fluctuations in the vessel draft due to fuel and water usage were not determined.

SwathPlus bathymetric sonar was configured in a rigid pole-mount and deployed from the starboard side of the R/V Connecticut. A TSS DMS 2-05 motion sensor was mounted directly above and in-line with the transducers. An RTK-GPS antenna was mounted adjacent to the rigid-pole mount. Horizontal (x and y) and vertical (z) offsets between the transducers and motion sensor and antenna and motion sensor were precisely measured and recorded within the SwathPlus acquisition software (SEA Swath Processor (2005)). These offsets are used to establish the motion sensor as the common reference point for data acquisition. Additionally, the depth of the transducers below the water surface was measured and recorded within the SEA Swath Processor acquisition software. This depth was used to derive the speed of profile and acoustic ray path based on speed of sound profiles collected within the survey area. An Applied Microsystems SV Plus sound velocity profiler was used to collect speed of sound profiles at forty-two stations. 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 (30 degrees)). The calculated roll angle offsets were stored within the SEA Swath Processor acquisition software. Navigation: The USGS established a Real-Time Kinematic Global Positioning System (RTK-GPS) that provided horizontal (x and y) and vertical (z) positioning during the survey. The RTK-corrected GPS signal was sent to the ship once every second from a base station positioned on the roof of the Air Force Antenna Station (USAF/AFRC/SNHA) in Ipswich, Massachusetts. Shipboard navigation data (x, y, and z) were stored in Hypack, Inc. Hydrographic Survey Software (http://www.hypack.com) raw data files and used for positioning of geophysical instrumentation. The offset between orthometric (NAVD88) and local chart datum (MLLW) as reported at the NOAA Tidal Station #8440452, Parker River National Wildlife Refuge, was applied to the RTK signal. This allows for elevations (z) received at the shipboard RTK antenna to be referenced to Mean Lower Low Water (MLLW) (that is, elevations are stored as distance of the RTK antenna above MLLW). During post-processing, the distance of the RTK antenna above the water-line is removed from the stored RTK elevations. The resulting value is then applied to the bathymetric soundings, yielding data referenced to MLLW. Process_Step: Process_Description: Tidal correction: Depths were corrected to mean lower low water (MLLW) using 1 second RTK-GPS heights of the GPS receiver mounted over the SwathPlus sonar head. These heights were extracted from each Hypack navigation file using the AWK script "DoRTK1" and smoothed in MatLab (ver. 7.1.0.183 R14) using a third order polynomial. The smoothed 1 second heights were averaged to 1 minute heights and formatted for input to Swath Processor using the AWK script "DoRTK2" . This text file was then inserted in the tide table in the SEA Swath Processor file (*.sxs) for merging with the SwathPlus Raw (*.sxr) file.

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 such as range and nadir to eliminate outliers. During this conversion process the tidal information from the previous process step was merged into the new processed file (*.sxp).

Each SwathPlus processed file (*.sxp) was imported to the new CARIS project using the Import/Conversion Wizard. A 5 meter resolution Bathymetric and Statistical Error (BASE) Surface was created from the files for each Julian day. The Base surface for each day was reviewed for any inconsistencies, or anomalies. Filters were applied to each line including beam to beam slopes and across track angle = 6.0 degrees. The CARIS refraction editor was used to adjust the speed of sound in some cases to flatten out the depth profiles produced by local differences in speed of sound.

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. This 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 from zip 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.
