Jaakko Putkonen likes being left out in the cold and biting winds, ice and snow.
Putkonen, a UND cold-climate researcher, returned earlier this month from his fifth expedition to Antarctica. The UND Geology and Geological Engineering Department assistant professor led a team of three UND students and a Vanderbilt University professor on the two-month expedition. Putkonen and the UND students downloaded data from probes that they had left there a year earlier and gathered up the equipment to take home.
