VIDEO: 150,000 Penguins Dead After Iceberg Renders Colony Landlocked
An estimated 150,000 penguins living in Antarctica have died in recent years after an iceberg the size of Rome became grounded near their colony, separating them from their food source: the sea.
The Guardian reports:
The penguins of Cape Denison in Commonwealth Bay used to live close to a large body of open water. However, in 2010 a colossal iceberg measuring 2900sq km became trapped in the bay, rendering the colony effectively landlocked.
Penguins seeking food must now waddle 60km to the coast to fish. Over the years, the arduous journey has had a devastating effect on the size of the colony.
Since 2011 the colony of 160,000 penguins has shrunk to just 10,000, according to research carried out by the Climate Change Research Centre at Australia’s University of New South Wales. Scientists predict the colony will be gone in 20 years unless the sea ice breaks up or the giant iceberg, dubbed B09B, is dislodged.
Penguins have been recorded in the area for more than 100 years. But the outlook for the penguins remaining at Cape Denison is dire.
“The arrival of iceberg B09B in Commonwealth Bay, East Antarctica, and subsequent fast ice expansion has dramatically increased the distance Adélie penguins breeding at Cape Denison must travel in search of food,” said the researchers in an article in Antarctic Science.
