The penguin colony had previously been identified through satellite imagery by researchers from the British Antarctic Survey. The penguins themselves didn't show up very clearly, but their excrement stains on the ice did.

Expedition leader Alain Hubert, who has spent seven seasons in Antarctica, long suspected a colony existed somewhere along the vast coast near Princess Elisabeth station. "When you go on the coast," explained the Belgian explorer, "after ten minutes, penguins come out of the water to look at who you are and what you are doing."

The satellite images gave Hubert and his team a rough idea of where to start looking. When ice research brought them within 37 miles (60 kilometers) of the probable location, they hopped
