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. To get to Greenland, scientists fly with the 109th Air National Guard in a Hercules C-130 aircraft. It is definitely not your typical airline experience. 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. A witty public service announcement for The Superstition Obstacle Course, where visitors were invited to challenge some superstitions. Superstition Obstacle Course was part of the Mind exhibit collection. 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.
Ice Stories correspondent Chico Perales is a great adventurer, photographer, and field coordinator for scientists. He's spent many seasons in Antarctica, but has finally made North to Barrow. Join us as we listen to Chico's incredible tales from both poles, and learn about what it takes to get scientists out on the ice. How does the interaction of solar radiation on sea ice effect climate change?
Please join us as we chat live with Dr. Don Perovich, an expert in the fields of albedo effect, and sea-ice mass balance on climate.
Brendan Kelly learned from Inuit hunters how to train Labrador retrievers to find ringed seals. This allows Brendan and his colleagues to set up live-capture nets to keep the seals from diving after they come up for air. The seals are tagged with satellite transponders so they can be tracked to learn about their breeding grounds and migration habits.
