image: An automated meteorological station next to Lake El'gygytgyn collected data on air and ground temperatures, precipitation, snow depth and solar insolation, among other parameters, for eight years. This data allowed the science team to compare modern climate and weather data to the paleoclimate data from the lake sediments. This image relates to a paper that appeared in the May 9, 2013, issue of Science Express, published by AAAS. The paper, by Julie Brigham-Grette at University of Massachusetts in Amherst, Mass., and colleagues was titled, "Pliocene Warmth, Polar Amplification, and Stepped Pleistocene Cooling Recorded in NE Arctic Russia." view more
