Emperor penguins in Antarctica surround Paul Ponganis of the Scripps Institution of Oceanography at UC San Diego as he removes a large cork emplaced over a study dive hole. The corks keep the holes from freezing over and keep the study penguins from diving before the researchers are ready to track them. At times, the penguins stand on the cork to protest as they await the opening of the hole.
