An icy mission on climate change

Posted: Thursday, Feb 14th, 2013


A trip to Antarctica was part of Christmas break for South Dakota State University scientists working on the West Antarctica Ice Sheet Divide Ice Core project.  Dave Ferris, left, a former SDSU postdoctoral researcher, was on the ice drilling crew, while professor Jihong Cole-Dai of the SDSU Chemistry and Biochemistry Department, and his graduate student, Kari Peterson, helped process the replicate core. / The National Science Foundation-funded Replicate Core Drilling Team accomplished something that’s never been done before. It went down the original ice core hole and brought up five cylinders of ice from designated time periods while leaving the borehole intact.

• SDSU scientists help retrieve more ice from West Antarctica

BROOKINGS – A slice of ice from 17,500 years ago can help scientists figure out how the Earth came out of the Ice Age and how climate change can happen in the future, according to South Dakota State University Professor Jihong Cole-Dai of the chemistry and biochemistry department.

He and graduate student Kari Peterson spent nearly a month in Antarctica during Christmas break as part of the West Antarctica Ice Sheet Divide Ice Core project.

The main goal of the ice core project, Cole-Dai said “was to get an ice core more than 2 miles deep to give us nearly 70,000 years of history of the Earth’s climate.”
