Research and Activities

McCarthy specializes in running laboratory experiments that explore how ice and other geologic materials respond to external forcing. In particular she is interested in how features at the microscopic scale affect macroscopic-scale behavior, such as how glaciers flow or how seismic waves are damped as they travel through the earth. Defects in the structure of crystalline materials, such as impurities, dislocations, grain boundaries, and partial melt, all affect the way that seismic waves are damped in the mantle or how tidal energy is turned into heat within an icy moon's outer shell. With material properties being the constant element, McCarthy’s work spans a variety of time and length scales and geologic contexts--from the deep earth, to the cryosphere, to the outer solar system.

 

Prior to joining Lamont-Doherty, McCarthy conducted postdoctoral research at the Earthquake Research Institute at the University of Tokyo in Japan. She is the recipient of the Lamont-Doherty Earth Observatory Postdoctoral Fellowship as well as the NASA Early Career Fellowship.

Christine McCarthy: A Cheerleader for the Physics of Ice (June 26, 2017, Lamont-Doherty Earth Observatory)

“Christine McCarthy is an ice squeezer: In her lab at the Lamont-Doherty Earth Observatory she scrunches blocks of ice up against slabs of rock, puts them under pressure and studies how the ice moves. These small-scale experiments in physics provide clues to how massive glaciers around the world move. It’s important information if you’re trying to understand how fast and how soon the ice sheets of Antarctica and Greenland might slide into the ocean and raise sea levels as the climate warms. In this video, the latest in a series about what we do at the Earth Institute, McCarthy, a Lamont assistant research professor, talks about her work and how her passion for rock climbing helped turn her into a scientist.”
