24 Oct 2012: Plastic Waste Increasing
On Remote Arctic Seabed, Cameras Reveal

Deep-sea cameras deployed to monitor biodiversity on the Arctic seabed have documented a significant rise in the amount of plastic waste and other litter on the remote sea floors of the Far North, according to a new study. While looking at many thousands of seabed photos taken in 2011 between Greenland

and the Norwegian island of Spitzbergen, deep-sea expert Melanie Bergmann of the Alfred Wegener Institute for Polar and Marine Research was struck by the number showing plastic waste. In a detailed analysis of the photographs — which are taken every 30 seconds by a deep-sea observatory reaching depths of 2,500 meters — Bergmann and her colleagues found that while plastic waste was seen in only one percent of photographs taken in 2002, that number had jumped to 2 percent in 2011. Two percent may not seem like a high occurrence, Bergmann said, but the quantities observed in this remote Arctic region were greater than recorded in a deep-sea canyon near Lisbon, Portugal. According to the study, published in the journal Marine Pollution Bulletin, about 70 percent of the plastic litter had come in contact with deep-sea organisms. Bergmann noted that “under these [dark and cold] conditions plastic waste can probably persist for centuries.”
