Secrets of Antarctica’s 15-Million Year-Old Lake

Researchers have thawed ice estimated to be perhaps a million years old or more from above Lake Vostok, an ancient lake that lies hidden more than two miles beneath the frozen surface of Antarctica using novel genomic techniques to determine how tiny, living “time capsules” survived the ages in total darkness, in freezing cold, and without food and energy from the sun.

Lake Vostok is located beneath four kilometers of ice in East Antarctica. The lake is approximately 250 km long and 50 km wide. The overlying ice provides a continuous paleo-climatic record of 400,000 years, although the lake water itself may have been isolated for as long as 15 million years.

Animation of Giant Iceberg Collision as Seen From Space

The collision in early February of the 60-mile-long B-9B iceberg with the protruding tongue of the Mertz Glacier in East Antarctica is captured here in a series of satellite radar images.

The crash created a second massive iceberg nearly 50 miles long and 25 miles wide, named C-28. The name means that it’s the 28th glacier since 1976 that has broken off from the quadrant of Antarctica that faces Australia.
