We observed the wastage of ice masses on the Kerguelen Islands (Indian Ocean, 49°S, 69°E) using historical information and recent satellite data. Overall, the total ice-covered area on the islands declined from 703 to 552 km 2 between 1963 and 2001, a reduction of 21%. The area of Cook ice cap (the...
