Description:

Abstract:

The USGS Woods Hole Science Center conducted a nearshore geophysical survey offshore of the southern coast of Martha's Vineyard, in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) in August 2007. This mapping program was part of a larger research effort supporting the Office of Naval Research (ONR) Ripples Directed-Research Initiative (DRI) studies at MVCO by providing data collection and modeling. The geophysical mapping utilized a suite of high-resolution instrumentation including sidescan-sonar, interferometric sonar, and sub bottom profiling. These data will be used as initial conditions for wave and circulation models for the study area. Ultimately, geophysical mapping, oceanographic measurements and modeling will help to improve our understanding of coastal sediment-transport processes.

This dataset is a subset of the National Oceanic and Atmospheric Administration (NOAA), National Geophysical Data Center (NGDC) Coastal Relief Model (CRM) in which topographic data from USGS 3-arc-second digital elevation models (DEM) and Shuttle Radar Topography data (SRTM) are combined with U.S. National Ocean Service (NOS) Hydrographic database to create seamless topographic-bathymetric image along the conterminous U.S. coastal zone, Puerto Rico, and Hawaii (Divins and Metzger, 2009). The CRM provides a comprehensive view of US coastal lands and adjacent offshore waters. The offshore extent is based on the NOS data supporting a continuous view of the seafloor (www.ngdc.noaa.gov/mgg/coastasl/crm.html).

Divins, D.L., and D. Metzger, 2009, NGDC Coastal Relief Model, <http://www.ngdc.noaa.gov/mgg/coastal/coastal.html>

Data_Quality_Information:

Logical_Consistency_Report:

This image contains all topographic and bathymetric data available within the National Atmospheric and Oceanic Administration, National Geophysical Data Center, (NGDC) Coastal Relief Model between 71 and 70 degrees longitude and 42 and 41 degrees latitude. Quality control checks were performed on these data by the NGDC during generation of the Coastal Relief Model (www.ngdc.noaa.gov/mgg/coastal/crm.html)

Completeness_Report:

This image contains all topographic and bathymetric data available within the National Atmospheric and Oceanic Administration, National Geophysical Data Center, Coastal Relief Model between 71 and 70 degrees longitude and 42 and 41 degrees latitude.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The National Geophysical Data Center (NGDC) reports that the bathymetric soundings used to generate the U.S. East Coast grids are referenced to various horizontal datum; NAD27 for soundings collected up until 1987-1988, and NAD83 for soundings collected 1988 to present. The NGDC further reports that the use of various horizontal datum does not significantly alter the accuracy of the East Coast grids because the horizontal difference between NAD27 and NAD83 is less than the horizontal resolution of the cells within the grids (< 90m).

(<http://www.ngdc.noaa.gov/mgg/coastal/model.html>)

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The National Geophysical Data Center (NGDC) reports that the bathymetric soundings used to generate the U.S. East Coast grids are referenced to two vertical datum; mean low water (89% of the surveys) and mean lower low water (11% of the surveys). The NGDC further reports that the use of two vertical datum does not alter the accuracy of the East Coast grids because there is little difference between the elevation in mean low water and mean lower low water within the gridding region.

Process_Step:

Process_Description:

The ASCII raster grid was imported to ESRI ArcMap 9.2 using ArcCatalog's Conversion Tools, ASCII to Raster. The output data type was float and the projection was: geographic coordinate system, NAD83.

The geographic grid was then reprojected to a UTM projection, zone 19N, WGS84 using ArcCatalog's Data Management Tools, Projections and Transformations, Raster, Project Raster. A Geographic Transformation NAD1983 to WGS1984_8 was used to transform horizontal datum from NAD83 to WGS84.

A color map ranging from blues to greens was defined for the resulting grid within ArcMap using the Legend Classifier within VACExtras, version 1.8, in order to define multiple intervals for the classified symbology: 5 meter interval between -55 and -20 depth, 1 meter interval between -20 depths and 20 elevations, and 5 meter interval 20 to 110 meter elevations.

A hillshade was then generated using Spatial Analyst, Surface Analyst, Hillshade feature. The parameters used were: Azimuth: 315, Altitude: 45, Z factor: 10, and output cell size: 92.499695 (default).

The CRM grid was displayed within ArcMap with 40 percent transparency. The hillshade was displayed with the CRM grid to display a color-encoded shaded relief image of the CRM grid.

The display of the color-encoded shaded relief image was then saved as a TIF image by using File, Export Map within ArcMap using the following parameters: 24-bit true color, no compression, write GeoTIFF Tags. This method reduced the resolution from the original 90-m grid cell size to a 135-m cell size.
