Ice Age: Vanderbilt expedition to Antarctica studies ice and how it has changed over millions of years

It was winter 2018 back in Nashville, but 10,000 miles away in Antarctica it was austral summer, the season of 24/7 sun in the Southern Hemisphere. A small team that included Morgan, senior lecturer in Earth and environmental sciences, and Grant had traveled to the frozen continent to study ice and how it has changed over millions of years. “I’m really interested in climate change and how it actually impacts the ice,” says Morgan. “We examine the record that ice leaves on the landscape to understand how the ice has changed over time. The Antarctic Ice Sheet plays a really important role in how Earth’s systems function, so what happens there impacts the whole planet.” Morgan hopes to return to Antarctica this November.
