Description:
Abstract:
Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Vineyard and western Nantucket Sounds, Massachusetts. These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs, and surficial sediment samples. The interpretation of the seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of Massachusetts.
Purpose:
This bathymetric grid was created as a single continuous surface for the sea floor of Vineyard and western Nantucket Sounds. These data helped define the sediment texture and distribution maps presented as interpretive data layers in USGS OFR 2016-1119

Publication_Information:
Publication_Place: Woods Hole Coastal and Marine Science Center, Woods Hole, MA
Publisher: U.S. Geological Survey, Coastal and Marine Geology Program
Other_Citation_Details:
Geologic mapping of the Massachusetts inner continental shelf is a cooperative effort that was initiated in 2003 by the U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM). The National Oceanic and Atmospheric Administration (NOAA-NOS) is also an important partner and contributes hydrographic data that are integrated into the maps. The overall goal of this cooperative is to determine the geologic framework of the sea floor inside the 3-mile limit of State waters, using high-resolution geophysical techniques, sediment sampling, and sea-floor photography. These topographic and bathymetric source data related to the composite topographic and bathymetric grid are cited in detail in the source citation section of this metadata file.

Data_Quality_Information:
Logical_Consistency_Report:
This bathymetric grid was created from several smaller bathymetry and lidar datasets that were processed and published in various formats and datums (see Source Information for the individual input data). NOAA single-beam sonar soundings and lead-line soundings were merged with the swath bathymetry and lidar. Bathymetric source datasets that were referenced to tidal datums (mean lower low water) were transformed to the North American Vertical Datum of 1988 (NAVD 88) using VDATUM (version 3.2). Individual datasets were imported into ArcGIS, evaluated for overlap and edited to subsets (generally on the basis of source quality, sounding density, and temporal relevance), compiled into a terrain model, then exported to an interpolated grid at 10 meters per pixel using the Natural Neighbors algorithm. The final output bathymetric DEM is composed of the best available bathymetric data for Vineyard and western Nantucket Sounds at the time of this publication.
Completeness_Report:
This grid includes lead-line soundings, single-beam sonar, swath interferometric, multibeam, and lidar data collected during several surveys in Vineyard and western Nantucket Sounds. The input grids can be downloaded by visiting the publications listed in the Source Information.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of the source multibeam bathymetry (DGPS) is reported at +/- 3 meters. The horizontal accuracy of the swath bathymetry (DGPS and/or RTK-GPS) is conservatively estimated to be +/- 10 meters. The lidar data were collected to meet the +/- 3-meter accuracy specification. Horizontal accuracy for lead-line and single-beam sonar soundings are not documented. This composite topographic and bathymetric grid is assumed to be horizontally accurate to within 20 meters, as additional errors could have been introduced during resampling, vertical and horizontal reprojections, and interpolation. See USGS Open File Reports and NOAA survey descriptive reports for individual survey positioning methods.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical accuracy for NOAA lead-line and single-beam sonar soundings are not documented. NOAA survey methods and processing of sounding data are in descriptive reports. All XYZ sounding data downloaded from NGDC are in tenths of meters. The vertical accuracy of the source multibeam bathymetry (RESON SeaBat 8101) is reported at +/- 30 to 50 cm. The vertical accuracy of the swath bathymetry is estimated to be +/- 10 to 60 cm. The lidar data were collected to meet the +/- 30-cm accuracy specification. This composite topographic and bathymetric grid is assumed to be vertically accurate to within 1-meter, as additional errors could have been introduced during resampling, vertical and horizontal reprojections, and interpolation.

This publication provides the source multibeam bathymetry for the Quicks Hole area. Two 29-foot launches deployed from the NOAA Ship Thomas Jefferson were used to acquire bathymetric and backscatter data during 2004. The multibeam bathymetric data were collected with hull-mounted 455-kHz RESON 8125 and 240-kHz RESON 8101 systems. The sidescan-sonar data were acquired with a hull-mounted Klein 5250 system operating at 100 kHz. Sediment samples and bottom photos were collected aboard the R/V Rafael with a modified Van Veen grab sampler and SEABOSS, respectively.

These data include NOAA lead-line and single-beam sonar soundings, which were used to cover areas where no swath bathymetry or lidar data exist.
Process_Step:
Process_Description:
Collected and prepared non-USGS source datasets: NOAA data from NOS hydrographic surveys in the 1900s (lead-line and single-beam soundings) were downloaded from the NGDC website individually (http://maps.ngdc.noaa.gov/viewers/bathymetry/) in XYZ ASCII format; the data are referenced to Geographic NAD83 and Mean Lower Low Water. Data from NOAA NOS hydrographic surveys conducted since 2000 were also downloaded from the NGDC website. The 2000 era data were in either XYZ or BAG format, and referenced to UTM Zone 19N, and Mean Lower Low Water. The following NOAA NOS survey data were used: 1930s - H06348, H06349, H06350, H06468; 1940's - H06533; 1950s - H08170; 1960s - H08820, H08821, H08902, H08903, H08904; 1970s - H09645, H09646; 2000s - H11920, H11921. Datasets obtained in BAG format were imported into Fledermaus (v7.4.0) then exported to XYZ text format. USACE JALBTCX lidar data were obtained online from the NOAA Coastal Services Center Digital Coast Data Access Viewer, which provided an ftp download of a subset of the bathymetric lidar data within a defined area of interest. The data were delivered in XYZ format, and referenced to Geographic NAD83 and NAVD88. XYZ coordinates referenced to NAD 83 were projected to UTM Zone 19N using proj (v4.8.0).

Process_Description:
Evaluated source data overlap and created subsets for contribution to composite surface: Overlap of the swath bathymetry and lidar datasets was evaluated using polygon feature classes representing the areal outlines of the published grids and points. Point feature retention was determined by the following preferential hierarchy; 1) USGS swath-interferometric data (2012-1006, 2011-1184, and 2013-1020), 2) NOAA-NOS multibeam data (from USGS Open File Reports 2006-1357, 2008-1004, 2009-1001, and NOS Descriptive Reports H11920, H11921), 3) USACE-JABLTCX Lidar, and 4) NOS leadline and single-beam. Polygon outlines of higher-ranked source datasets were used to spatially select coincident points from lower-ranked XYZ feature datasets and delete them. After redundant source XYZ feature data were eliminated, the remaining subsets were imported to an ArcGIS (v9.3) geodatabase as point feature classes.

An ArcGIS (9.3.1) Terrain Dataset was created (ArcToolbox > 3D Analyst Tools > Terrain > Create Terrain), all of the contributing point feature datasets and a polygon feature encompassing the input points (used as a hard clip) were added to the terrain (ArcToolbox > 3D Analyst Tools > Terrain > Add Feature Class to Terrain), and the terrain was constructed (ArcToolbox > 3D Analyst Tools > Terrain > Build Terrain).

Process_Description:
The composite bathymetry was converted from the Terrain Dataset to a 10 meter per pixel, floating point Esri Grid (vns10m_navd88) using the natural neighbors interpolation method (ArcToolbox > 3D Analyst Tools > Conversion > From Terrain > Terrain to Raster). During the conversion, the polygon area encompassing the input points was specified to clip the extent of the output grid (Environmental Settings > Raster Analysis Settings > Mask)
