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.

These photographs, taken from the International Space Station in January, 2004, show two pieces of a massive iceberg that broke off from the Ronne Ice Shelf in October, 1998. The pieces of iceberg A-38 have floated relatively close to South Georgia Island. After 5 years and 3 months adrift, they are approximately 1,500 nautical miles from their origin. In the oblique image, taken a few minutes later, the cloud pattern reveals the impact of the mountainous islands on the local wind field. At this time, the icebergs are sheltered in the lee side of the island.

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.
