150,000 Antarctica penguins die after iceberg grounding: study
Some 150,000 penguins died after a massive iceberg grounded near their colony in Antarctica, forcing them to make a lengthy trek to find food, scientists say in a newly-published study.
The B09B iceberg, measuring some 100 square kilometres (38.6 square miles), grounded in Commonwealth Bay in East Antarctica in December 2010, the researchers from Australia and New Zealand wrote in the Antarctic Science journal.
The Adelie penguin population at the bay's Cape Denison was measured to be about 160,000 in February 2011 but by December 2013 it had plunged to an estimated 10,000, they said.
The iceberg's grounding meant the penguins had to walk more than 60 kilometres (37 miles) to find food, impeding their breeding attempts, said the researchers from the University of New South Wales' (UNSW) Climate Change Research Centre and New Zealand's West Coast Penguin Trust.
