The history of the East Antarctic Ice Sheet is written in stones along the Transantarctic Mountains. Over the past two years, researchers ventured to remote areas along the mountain range to decipher how high ancient glaciers reached, by studying the rocks they left behind. By measuring the amount of cosmic radiation the rocks have been exposed to, the research team can map out the reach of ancient glaciers at different points in the past.

The tagging project ties in with a broader effort that he's been spearheading for 20 years, monitoring Adelie penguin populations and demographics around Ross Island.
