Geologic Mapping of the Massachusetts Sea Floor
The U.S. Geological Survey, in cooperation with the Massachusetts Office of Coastal Zone Management (CZM) is conducting geologic mapping of the sea floor to characterize the surface and shallow subsurface geologic framework within the Massachusetts coastal zone. The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) that will serve the needs of research, management and the public. This project page provides a description of the mapping program and links to data and publications produced for this project and other Massachusetts mapping efforts.
Data Collection and Interpretation
Surveys conducted in Massachusetts waters between 2003 and 2013 have provided bathymetric, acoustic backscatter, seismic-reflection profile, sample, and photograph data that are used to create high resolution geophysical datasets that guide sea floor characterization and the production of interpretive maps.
Geophysical and Sample Data Products
Bathymetric and acoustic backscatter data collected at 100 percent sea floor coverage and seismic reflection profiles provide an unprecedented, high resolution perspective of the Massachusetts coastal environment. These data are useful to scientists and managers alike as a foundation for scientific investigations and resource management
Interpretations of high-resolution geophysical data, sediment samples, and bottom photographs are used to produce a series of maps that describe the distribution and texture of sea floor sediments, shallow geologic framework, and physiographic zones of the Massachusetts inner continental shelf.
