To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae.
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.
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.
