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. Join us as we celebrate the beginning of summer in the Arctic and the long, cold winter in Antarctica. We'll connect live to two polar field sites: Summit Camp atop Greenland's vast ice sheet, where the sun will be shining 24 hours a day, and the South Pole Research Station, now in the middle of 6 months of darkness.
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. In today's program Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, talks about the research he and his team are doing on arctic breeding shorebirds in Barrow, 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. Join us for this special Webcast from Summit Camp, which sits atop nearly 2 miles (about 3200 m) of ice on the Greenland ice cap. We'll talk with Zoe Courville, an Ice Stories blogger and snow researcher from the Cold Regions Research and Engineering Lab, about life on top of an ice sheet. She'll also discuss her research into how snow becomes glaciers. 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.
