Antarctica - July 2nd, 2009

Icebergs continue to break off the Wilkins Ice Shelf near its connection to Latady Island (bottom left quadrant). The last time this area was observed (click here for previous article), the left side of the ice connecting the shelf to the island was cracking.

In this image, taken six weeks later, the ice around those cracks has splintered off entirely, leaving the edges smooth once again and adding more icebergs to those floating nearby in the open ocean.

Upon opening the full, orthorectified image the peaks of the Douglas Range on Alexander Island can be seen towards the top. These mountains are part of a sharp-crested range, with peaks rising to 3,000 metres.

The range extends 120 km (75 mi) in a northwest-southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound.
