B15A has blocked wind and water currents that break up ice floes in McMurdo Sound during the Antarctic summer, causing a build-up of ice behind it.The ice blockage has also threatened penguin breeding colonies, with tens of thousands of Adele penguin chicks facing starvation as parent birds are forced to trudge up to 110 miles to open sea to gather food.
