Ice shelves are thick slabs of ice that are attached to coastlines and extend out over the ocean. In the natural course of events, ice shelves often calve large icebergs. On February 28, 2008, however, the Wilkins Ice Shelf rapidly disintegrated into small pieces.

Moderate-resolution Imaging Spectroradiometer (MODIS) satellite imagery analyzed at the University of Colorado’s National Snow and Ice Data Center revealed that the northern section of the Larsen B ice shelf, a large floating ice mass on the eastern side of the Antarctic Peninsula, has shattered and separated from the continent. This particular image was taken on March 5, 2002.

The northernmost arm of Antarctica is a hotspot of research because its retreating glaciers are a large contributor to sea level rise.

Changing weather conditions left their mark on sea ice along the Antarctic Peninsula in late 2008 and early 2009. In mid-December 2008, melt water resting on the sea ice colored it sky blue. At the beginning of 2009, however, the sea ice appeared snowy white, and cracks had begun along the ice margin.

The tip of the Antarctic Peninsula showed dramatic seasonal changes in late January 2008. On January 24, 2008, the fast ice looked solidly frozen. Several days later, on January 30, 2008, the ice’s new blue hue suggested something had changed.

n late February 2008, an ice shelf on the Antarctic Peninsula disintegrated into a floating pile of massive ice bergs, smaller ice fragments, and slush that was trapped in place by freezing sea water over subsequent weeks. This highly detailed image from the Taiwanese Formosat-2 satellite shows the different sizes, shapes, and textures of the ice fragments on March 8, 2008.
