Scientists say an estimated 150,000 Adelie penguins have been wiped out on Antarctica's Cape Denison in the five years since a giant iceberg blocked their main access to food. A study recently published in the journal Antarctic Science says the B09B iceberg crashed with the Mertz Glacier Tongue and got stuck in Commonwealth Bay, an area that was rarely covered by sea-ice, making it ideal for Adelie penguin colonies.
A U.S. Coast Guard heavy icebreaker left Australia for Antarctica on Sunday to rescue more than 120 crew members aboard two icebreakers trapped in pack ice near the frozen continent’s eastern edge, officials said. The 122-meter cutter, the Polar Star, is responding to a Jan. 3 request from Australia, Russia and China to assist the Russian and Chinese ships.
