In this webcast from Antarctica, we meet up with Ted Scambos, a glaciologist from the University of Colorado and the National Snow and Ice Data Center. Dr. Marvin Speece, professor of geophysical engineering at Montana Tech and co-Principal Investigator of the Offshore New Harbor Project, discusses how their expedition collects scientific data. From a small rubber boat on a Greenlandic lake, climate researcher Billy D'Andrea introduces some of the equipment scientists use in limnological sampling. (Limnology is the study of freshwater systems, like lakes.) Working in the snow all day takes a certain type of skill set: digging skills, drilling skills, and snowmobile driving skills. It also helps to love what you do. Climate researcher Billy D'Andrea and colleagues explore the remote "back lakes" of Greenland. 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.
