Live from the Arctic: Unlocking Earth's Environmental History

The ice sheets near the Earth’s poles contain ancient ice formed from continuous snow accumulation over thousands of years. Using ice cores, scientists can study the old air trapped in the ice, which unlocks mysteries of Earth’s environmental history.

On June 27 at 1 pm EST, 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!
