Marine Debris on Davidson Seamount: 4,000 to 11,500 Feet Deep

Poster presentation at Sanctuary Currents Symposium, Seaside, CA
Davidson Seamount, part of the Monterey Bay National Marine Sanctuary, is considered a relatively pristine habitat. We documented marine debris over 176 kilometers using video transects and still images from NOAA/MBARI cruises in 2002 and 2006. Forty-four pieces of marine debris were documented with 41% being metal and 25% being plastic. These included bowls, buckets, cans, a broom, plastic bags, and train wheels. This debris mostly rains down from boat discards, as opposed to other deep-sea habitats where debris can originate from the shoreline and is pushed by currents along the continental shelf and into canyons.
