150,000 Antarctic penguins died after a massive iceberg grounding

© Nasa/AFP/FileSydney (AFP) - 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. "The Cape Denison population could be extirpated within 20 years unless B09B relocates or the now perennial fast ice within the bay breaks out," they wrote in the research published in February. Fast ice is sea ice which forms and stays fast along the coast. © Nasa/AFP/File During their census in December 2013, the researchers said "hundreds of abandoned eggs were noted, and the ground was littered with the freeze-dried carcasses of previous season's chicks". "It's eerily silent now," UNSW's Chris Turney, who led the 2013 expedition, told the Sydney Morning Herald Friday. "The ones that we saw at Cape Denison were incredibly docile, lethargic, almost unaware of your existence. "The ones that are surviving are clearly struggling.

Today, strategy gets top billing at design studios. It’s just the latest reinvention for designers.
