Cool off: Count seals in Antarctica from the comfort of your couch

Pretty cool--you can count seals in Antarctica, right from your couch, via satellite images. Dr. Michelle LaRue is a research ecologist at the U of MN Department of Earth Sciences and lead researcher on the project, which is called "Satellites Over Seals." She talked with Dick about what they're studying, why the seal count is important, and why they've turned to the public for help. It's easy to get started counting seals--just go to www.tomnod.com and follow the instructions.
