From atop the Greenland Ice Sheet, Chris Linder, a photographer from Woods Hole Oceanographic Institution, describes observing first-hand the sudden rapid draining of a huge glacial lake. 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.) 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. Meet glaciologist Slawek Tulaczyk and his team, who work in the fast-emerging field of ice sheet dynamics. They speak to us just after returning from a month at a remote camp on the West Antarctic Ice Sheet. Dr. Tulaczyk, a glaciologist from UC Santa Cruz, studies the lakes, floods, and ice quakes that occur under the giant glaciers of Antarctica. He is among only 200 scientists world-wide who study ice sheet dynamics and its role in climate change. NASA's Mars Exploration Rovers, Spirit and Opportunity, have long outlived their life expectancy of three months. Join us as we sum up the rover data and explain how this information changes our view of Mars. We update on the week's exciting events on Mars and talk about what NASA has planned for future missions to the Red Planet. How do JPL scientists and engineers talk to the MERs and how do we receive those amazing pictures in return? Find out how, and get the latest updates in this webcast. With two rovers on Mars, we update you on the latest findings. This week, hear (and see!) more about a tool called Mini-TES, which helps us learn about rocks on Mars.
