"Those bed materials, whether it’s sediment or hard bedrock contained within it, are the words, the stories of the history of the ice sheet—it’s a book of information down there that we want to read."

Jason Briner, professor and associate chair in the Department of Earth Sciences and GreenDrill project co-lead. Briner's team aims to collect bedrock samples from beneath the Greenland ice sheet to determine the last time it melted. The research is featured in an article in “Scientific America.”
