Sediments of Buzzards Bay, MA (HOUGH40)

공공데이터포털

The modern sediments of Buzzards Bay are described principally by the use of quantitative data from mechanical analyses. The environment of the sediment and its source and mode of deposition are discussed in the original publication. Although Hough (1940) is available as part of the NGDC Deck41 database, additional data from the original report were manually entered and, therefore, this file is unique.

Sediments of Buzzards Bay acquired in 1963 (MOORE63 shapefile)

공공데이터포털

A study of bottom sediment samples from Buzzards Bay, Massachusetts, provides a basis for establishing their major depositional facies and their relationships to the environmental framework. Texturally the sands tend to occur in shoaling areas of greater tidal-current activity, while the argillaceous sediments are deposited in deeper bathymetric entrapments.

Sediment-Texture Units of the Sea Floor for Buzzards Bay, Massachusetts (BuzzardsBay sedcover, polygon shapefile, Geographic, WGS84)

공공데이터포털

Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Buzzards Bay, 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.

Sediments of Cape Cod Bay, Massachusetts (HOUGH42 shapefile)

공공데이터포털

Cape Cod Bay, lying on the Massachusetts coast partly enclosed by Cape Cod, is in a glaciated region of low relief. Coarse sediments generally occur in areas exposed to wave and current action as in shallow water near shore or on shoals, and in the deep channel north of the tip of Cape Cod, which is swept by tidal currents. Fine sediments are restricted to the deeper water in the central portion of the Bay, and to the small well-protected embayments of the shore. Although Hough (1942) is available as part of the NGDC Deck 41 Database, additional data from the original report were manually entered and, therefore, this file is unque.
