James Lindholm, coordinator of the Stellwagen Sanctuary, presents on the science and technology currently being used just a few miles off the shore of Massachusetts. The exploration and the study of the marine environment presents numerous challenges, particularly in the northwest Atlantic where Stellwagen Bank National Marine Sanctuary is located. Rapid advance in science and engineering, however, have produced remotely operated vehicles, manned submersibles, and acoustic telemetry arrays, which offer scientists, as well as the public, a window into this previously unseen realm.
