Based in the West Antarctic Peninsula, the scientists fit selected penguins with satellite transmitters that allow them to map the penguins' tracks. Underwater vehicles then allow the scientists to examine the foraging habits of Adélie penguins, which are experiencing significant population declines.

The Antarctic team comprises UD's Matthew Oliver, assistant professor of oceanography in the College of Earth, Ocean, and Environment, and researchers from Rutgers University, Polar Oceans Research Group, and California Polytechnic Stat University in San Luis Obispo.
