What does a ringed seal’s breathing hole look like and how do you find one on a vast sheet of sea ice? Dr. Brendan Kelly uses the canine skills of Cooper, a Black Labrador he trained to chase the scent of ringed seals and point to their holes. Passionate about wildlife and climate change, Melanie Duchin has loaned her dog to work with Brendan for the past 5 years.

Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems.

Dr. Jewel Bennett, an endangered species biologist with the US Fish and Wildlife Service's Fairbanks field office, is in Barrow leading a survey team tracking the endangered Steller's and Spectacled Eiders' populations.

Watch Dr. Brendan Kelly, Micaela Ponce, Kevin Bakker and Dan Carlson as they measure and tag a female ringed seal on the frozen Chukchi Sea. Follow them as they return the seal by snowmobile to her breathing hole in the Elson Lagoon - and get a little seal slap in the process.

Inupiaq elders, local experts and scientific researchers partner on the North Slope to study and understand the changing environment. Wendy Eisner and Chris Cuomo join us to talk about their project: Indigenous Knowledge and Landscape in Northern Alaska.

Amanda Grannas' research group at Villanova University studies a wide range of topics under the umbrella of "analytical environmental chemistry", including the impacts of pollutants in the snow and ice. We'll chat with Amanda about her current research in the Arctic.

Dr. Vladimir Romanovsky is researching permafrost geophysics: the relationship between the frozen ground (permafrost) and climate. Join host Julie Konop as she asks Vladimir about his most recent data.

Weather permitting, correspondents Anne Jensen and Laura Thomas will have just returned from their first day at their field location at Nuvuk (a.k.a. Point Barrow). We'll take a look at conditions after the long winter, and watch as these scientists, and their students, prepare for a summer of digging.

As the Arctic continues to warm, chemicals locked in the snow can be released-either into the seas or evaporated into the air. Dr. Glenn Rowland studies the chemicals locked in the ice to help us understand what is there now and how it will react when released into the environment.
