The USGS Massachusetts Seafloor Mapping Cooperative Web Mapping Application contains published data layers and information from various research initiatives conducted by the U.S. Geological Survey, Coastal and Marine Geology Program (CMGP) in cooperation with the Massachusetts Office of Coastal Zone Management (CZM). An example of the default map view is shown at the right. This map view shows the coastal region of Massachusetts from Rhode Island to the New Hampshire border.

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 seafloor inside the 3-mile limit of State waters, using high-resolution geophysical techniques, sediment sampling, and seafloor photography. Water depths in the study area range from about 5 m (16 ft) along the coast to 90 m (295 ft) in offshore areas. From 2003-2008, this project has mapped approximately 1375 km² (530 mi²) of seafloor extending from the MA/NH border to northern Cape Cod Bay.

Data layers may be "turned-off or on" by selecting the visible button beside the layer name. The map view will automatically update. A complete description of the available data layers may be found in the GIS Data Catalog.
