Image Caption: Iceberg A22A, South Atlantic Ocean
This astronaut photograph illustrates the remains of a giant iceberg--designated A22A-- that broke off Antarctica in 2002. The iceberg was photographed on May 30 at a location of 49.9 degrees south latitude, 23.8 degrees west longitude, which is about a third of the distance from South America towards Cape Town, South Africa. A22A is one of the largest icebergs to drift as far north as 50 degrees south latitude, bringing it beneath the daylight path of the International Space Station (ISS). Crew members aboard the ISS were able to locate the ice mass and photograph it, despite the great masses of clouds that often accompany winter storms in the Southern Ocean. The crew's viewing angle was oblique (not looking straight down) from a point to the west of the berg, and the time of day was early afternoon, as shown by the orientation of the cloud shadows. Dimensions of A22A in early June were 49.9 by 23.4 kilometers, giving it an area of 622 square kilometers, or seven times the area of Manhattan Island. The outlined region labeled "Area of Detail" refers to an associated image ISS015-E-10118.
Images of the iceberg are being acquired from the ISS to support a study of massive icebergs--part of NASA International Polar Year activities. The study will increase understanding of the way ice sheets evolve as climate changes. When large masses of ice float into warmer waters north of their usual latitudes, they undergo change at rapidly increased rates. Changes that would take decades to occur in Antarctica can happen in a few years or even months in the warmer conditions at 50 degrees south latitude. The crew of the ISS will continue to collect imagery of the accelerating breakup of iceberg A22A as weather, orbital, and illumination conditions allow.
