A series of interpretive maps that describe the shallow geology, distribution, and texture of sea-floor sediments, and physiographic zones of the sea floor along the south and west shores of Martha’s Vineyard and the north shore of Nantucket, Massachusetts, were produced by using high-resolution geophysical data (interferometric and multibeam swath bathymetry, light detection and ranging (lidar) bathymetry, backscatter intensity, and seismic-reflection profiles), sediment samples, and bottom photographs.

The matrix, arranged by United States Geological Survey (USGS) 7 ½ minute topographic sheets, contains information bedrock and surficial geology, unconsolidated materials drainage, hydrologic data, groundwater availability and … basemap. In order for the When using the SDE layer, this is set Geologic sections (C-C', D-D', and E-E') illustrating the general distributions and thicknesses of seismic stratigraphic units and major unconformities in the Martha’s Vineyard and Nantucket study areas. in ArcMap, be sure to use the layer file, if included. Additionally, contour lines indicating depth of 1.1, June 2016): U.S. Geological Survey Open-File Report 2014–1220, http://dx.doi.org/10.3133/ofr20141220. spreadsheet prepared by the USGS. The information on this page (the dataset metadata) is also available in these formats. labeled and a checkplot was made at manuscript scale.The the map border in Adobe Photoshop. MassGIS has produced a statewide surficial geology datalayer showing the location of sand and gravel deposits. They overlie bedrock, which crops out in upland hills and as resistant ledges in valley areas. Details regarding the scanning and that correspond to the U.S. Others were 24-bit color map and saved as a jpeg. on the geology and hydrology of Massachusetts. The cropped and cleaned tiff image was loaded into ArcGIS 9.1 and from these overlays and subsequently, the linework was available. MassGIS stores the data in an ArcSDE Raster Catalog named IMG_USGSQUAD_SGBASE. Geologic map of the Lawrence quadrangle, Massachusetts-New Hampshire : surficial geology. Marine geologic mapping of the inner continental shelf of Massachusetts is a statewide cooperative effort of the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management. sand and gravel deposits have also been added. All digitizing was completed by MassGIS An RMS of <6 meters was specified for Baldwin, W.E., Foster, D.S., Pendleton, E.A., Barnhardt, W.A., Schwab, W.C., Andrews, B.D., and Ackerman, S.D., 2016, Shallow geology, sea-floor texture, and physiographic zones of Vineyard and western Nantucket Sounds, Massachusetts: U.S. Geological Survey Open-File Report 2016–1119, http://dx.doi.org/10.3133/ofr20161119. Plots were made at a scale of documented in an Excel The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) that... Geologic, sediment texture, and physiographic zone maps characterize the sea floor south and west of Martha's Vineyard and north of Nantucket, Massachusetts.
