CCAMLR-VIII

Neck collars of man-made marine debris were seen on 208 Antarctic fur seals (and removed from 170) during the 142 days of the 1988-89 pup-rearing season at Bird Island, South Georgia. This represents at least 0.1% of the total Bird Island population and a minimum of 0.4% of animals in the best covered areas; a maximum value might approach 1%. Poly-propylene straps (packaging bands) formed 59% Read More

Plastic particles were found to be common pollutants in stomachs of Wilson’s Storm Petrels and Cape Petrels breeding on the Antarctic continent. Highest incidence of plastics was found in chicks of Wilson’s Storm Petrels that had died before fledging. Few or no plastics were found in Snow Petrels and Antarctic Petrels. Evidence suggests that most plastics originate from wintering areas outside Read More

The coastline of subantarctic Macquarie Island (54° 35’S, 158° 55’E) was surveyed over an eight week period in 1988 to determine types, quantities, and possible sources of marine debris. Lost fishing gear consisted of buoys, ropes, and net fragments. Gear from both trawling and longline fishing operations were represented, with debris identified from Russian, Polish, Japanese, Taiwanese, and Read More

Sections of coastline of Heard and Macquarie Islands were surveyed for marine debris in summer 1987-88, and 1989 respectively. These surveys were carried out at the same sites of previous surveys in 1986-87 at Heard Island, and 1988 at Macquarie Island. The minimum rate of artefact accumulation was 13 objects km-1 year-1 for Heard Island, and 9.1 objects km-1 year-1 for Macquarie Island. Drift Read More

Plastic particles and Other anthropogenic materials were recorded from the regurgitations and the stomachs of seabirds at Macquarie Island; these were ingested both at sea and on land. Eight percent of regurgitated casts from Macquarie Island Cormorants contained polystyrene beads. Plastic particles were recorded from the stomachs of Southern Giant Petrels, Subantarctic Skuas, and Kelp Gulls. Read More

Global climate change has the potential to disrupt the delicately poised themal balance in surface waters of the Southern Ocean around Antarctica, threatening this highly productive system with severe and permanant collapse. Pivotal to this process is a diminution of the important (but little studied) CO2 sink in the Southern Ocean, resulting in a series of feedback loops accelerating global Read More
