In April 2005, the A53a iceberg calved off the Larsen Ice Shelf and began drifting north. Nearly three years later, it began to disintegrate.

In January, 2004, astronauts on board the International Space Station took this detailed picture of melt water pooled on the surface of iceberg A-39D, a 2-kilometer wide, 11-kilometer long iceberg and drifting near South Georgia Island. The different intensities of blue are interpreted as different water depths. From the orientation of the iceberg, the deepest water (darkest blue) lies at the westernmost end of the iceberg. The water pools have formed from snowmelt—late January is the peak of summer in the Southern Hemisphere.

The mega-iceberg A53a (upper image) measured close to 50 kilometers by 22 kilometers, about seven times the area of Manhattan Island, in mid-January 2008 when astronauts took the photographs for this mosaic. The images were acquired from the International Space Station (ISS), located 780 kilometers to the north of the iceberg at an altitude of 341 kilometers; the perspective distorts the oblong shape of the iceberg, making it look squarer than it actually is.

The iceberg A22A was photographed when it was 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). A series of parallel lines can be seen in the lower image. These are probably “hummocks,” dunes of snow that have solidified, and they date back to the time when the iceberg was connected to Antarctica. A developing fracture in the ice can be seen in the lower, detailed view.
