U.S. Geological Survey Open-File Report 2007-1373
High-Resolution Geologic Mapping of the Inner Continental Shelf: Cape Ann to Salisbury Beach, Massachusetts
A total of 834 bottom photographs were obtained along 88 drift lines as part of this study. (See Ground Validation in section 3 of this report). Typically 5-10 bottom photographs were obtained at each station with the SEABOSS system as the survey vessel drifted over the seafloor. The field of view of each image is approximately 50 cm wide when the camera is 50 cm off the bottom.
Photographs can be viewed in the photo-gallery pages below or in the GIS data in appendix 1.
