National Science Foundation Event. Live from the Arctic: Unlocking Earth's Environmental History, U.S. National Science Foundation

Join researchers from the University of California Irvine live from NSF Summit Station, Greenland as they study historical changes in atmospheric levels of hydrogen using a newly drilled ice core from the Greenland ice cap. Because of the unique challenges posed by hydrogen’s small molecular size, the researchers are bringing their instruments to Greenland to analyze samples as soon as they are retrieved.
