Five map sheets have been compiled showing the seafloor offshore of Massachusetts from Cape Ann to Salisbury Beach.  The text on each map sheet introduces the map, briefly describes the data and methods, and summarizes key features.  Section 3 (Data Collection and Processing) and Section 4 (Geologic Interpretation) provide more detailed information than presented on the map sheets.  Links to the maps at full scale, the map text, and a page-size map are provided on the USGS website:  http://woodshole.er.usgs.gov/project-pages/coastal_mass/
