NASA's Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the Polar Regions with the global climate system. IceBridge uses a specialized fleet of aircraft and the most sophisticated suite of science instruments ever assembled to gather data on sea ice, glaciers, and ice sheets. The data gathered today will allow future scientists

Article describing the final stages of this year's Operation IceBridge, the NASA campaign to maintain and expand on Arctic ice measurements. Along with PolarTREC teacher Mark Buesing, the IceBridge team has successfully completed a variety of aerial measurements on sea ice, sub-ice bedrock and Greenland's glaciers.
Press release about the launch of Operation IceBridge's 2013 season of research activity and science flights over Arctic ice sheets and sea ice. Operation Icebridge will undertake survey flights over land and sea ice in and around Greenland and the Arctic Ocean through early May in order to maintain a continuous record of polar ice measurements.
Article describing PolarTREC teacher Mark Buesing's upcoming expedition to Greenland in April to participate in NASA’s Operation IceBridge, a six-year mission to map polar ice.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
