Section 2 - Maps

Five map sheets (45" X 45") have been compiled showing the sea floor offshore of Massachusetts from Nahant to Gloucester. 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) in this report provide more detailed information than presented on the map sheets. Links to the map at full scale, the map text, and a page-size map are provided below in PDF format.
