The Conger Glacier was located off the east coast of Antarctica. Its area was almost 1,200 square kilometers. This is slightly more than the area of Moscow before the expansion in 2012.
Images of the destruction, obtained by Landsat and MODIS satellites, were tweeted by Kathryn Walker, a NASA Earth scientist and planetary scientist at the Woods Hole Oceanographic Institution.

Images posted by Walker show the shelf slowly receding through March 14. And an image from March 16 shows the glacier has completely cracked.
“Ice sheets are critical to containing the flow of ice from the continent into the sea. – notes Andrew McIntosh, a glacier researcher at Monash University in Australia. – If the containment shield collapses, the flow of ice from the land will accelerate and cause sea levels to rise.”
Scientists attribute the collapse of the glacier to the abnormal heat wave that set in Antarctica in March. Earlier Haytech wrote about the record warming, during which the temperature in the southernmost continent rose by 40°C above normal.
