英文摘要: Only 52 litter items (>1cm diameter) were observed in 10,467km of at-sea transects in the African sector of the Southern Ocean. Litter density north of the Subtropical Front (0.58 items km-2) was less than in the adjacent South Atlantic Ocean (1-6itemskm-2), but has increased compared to the mid-1980s. Litter density south of the Subtropical Front was an order of magnitude less than in temperate waters (0.032 items km-2). There was no difference in litter density between sub-Antarctic and Antarctic waters either side of the Antarctic Polar Front. Most litter was made of plastic (96%). Fishery-related debris comprised a greater proportion of litter south of the Subtropical Front (33%) than in temperate waters (13%), where packaging dominated litter items (68%). The results confirm that the Southern Ocean is the least polluted ocean in terms of drifting debris and suggest that most debris comes from local sources. © 2014 Elsevier Ltd.
