What makes ice sheets expand and contract, and why should we care? In this beautifully articulated talk, Professor Christina Hulbe shares the secrets of Antarctic ice flows, and the vulnerability of the Antarctic ice sheets in a warming world.
Professor Hulbe is a geophysicist who studies how and why polar ice sheets change over time. While she got her start in a remote west Antarctic field camp, most of her research today is computational, using mathematical models and remote sensing to investigate modern systems and the recent past.
She is Professor and Dean of Surveying at the University of Otago in New Zealand, and was previously Chair of the Geology Department at Portland State University in the United States.
In 2015, she returned to Antarctica to work with an interdisciplinary team from around New Zealand investigating the vulnerability of the Ross Ice Shelf in a warming world.
