Clarence Island is the easternmost of the South Shetland Islands, lying 30 km east of Elephant Island. Chinstrap Cove lies on the western shore of Clarence Island.
The IBA qualifies on the basis of the concentration of seabirds present (in particular Chinstrap Penguin (Pygoscelis antarctica)), and comprises all of the ice-free area south of Chinstrap Cove, extending around 2 km southwards along the coastline of Clarence Island.
Information on the environment at this site is not available. There are no research stations in the near vicinity, the closest being around 250 km to the southwest, on King George Island.
Approximately 19 500 pairs of Chinstrap and 770 pairs of Macaroni ( Eudyptes chrysolophus ) penguins were breeding on the ice-free area at the southern entrance point of Chinstrap Cove in 1977 (Croxall & Kirkwood 1979).
Non-bird biodiversity: None known.
