Examining Arctic lake sediment core
John Pohlman (USGS, left) and colleagues from the University of Alaska Fairbanks examine a sediment core retrieved through winter ice from the bottom of a lake in northern Alaska. Such cores are used to reconstruct methane emissions and climate history over the past 20,000 years.
