An Ongoing Field Study to Evaluate the Impacts and Direct Effects of Offshore Dreding Activities on Benthic Organismsby Barry S. Drucker, Office of Strategic and, International Minerals, Herndon, United States,
Abstract: Instrumentation and sampling involve box coring, otter trawling, the use of a towed sled carrying video camera, and a sidescan sonar device. The baseline collection phase of the study began in mid-July 1992, before the actual dredging of the sites. Subsequent cruises are scheduled to follow completion of dredging activities. Sampling will continue for approximately two years, when the overall degree of benthic repopulation will be evaluated and a report prepared.
