New data suggests a marine heat event could further destabilize Antarctica's massive ice shelves -- and the penguin habitat.
San Jose State University researchers are tracking Emperor Penguins in the Antarctic to study the effects of climate change.It's hard to imagine how emperor penguins project such an aura of calm and dignity, with everything happening around them. The birds were recently listed as endangered by U.S. Fish and Wildlife.
And now, new data suggests a marine heat event could further destabilize Antarctica's massive ice shelves -- and the penguin habitat. Enter a team from San Jose State's Moss Landing Marine Laboratories, who recently returned to the Crozier ice shelf, to monitor the penguin with an array of tracking devices.
"We're still trying to figure that out. We're primarily collecting baseline data now, but it's some of the colonies that are further north, some of the ice that they breed on is disappearing. So that's probably going to be what one of their first challenges is, as the sea ice becomes more unreliable. If the sea ice breaks out too soon, there can be complete reproductive failure," says associate professor Birgitte McDonald, Ph.D.
