icebergs

The European Space Agency's Sentinel-1A satellite, launched April 3, has sent back its first images, including one of icebergs in Antarctica.

Pine Island Glacier – one of the largest glaciers within the West Antarctic Ice Sheet – is about to undergo rapid, uncontrollable retreat, new research finds.

Hydrophone arrays complement satellite data to monitor iceberg movements.

The sounds of icebergs calving make the oceans a noisier place, which could make it more difficult for whales and other cetaceans to hear each other's calls, new research suggests.

An iceberg larger than the city of Chicago broke off from Antarctica's Pine Island Glacier this week. The newborn iceberg, which measures about 278 square miles, is floating in the Amundsen Sea.

A 13,000-foot-wide glacier breaks off into a fjord.

The threat of icebergs still exists 101 years after the RMS Titanic sank to the bottom of North Atlantic Ocean on April 15, 1912.
