In conjunction with the large, stunning photographs of icebergs by Camille Seaman in the main gallery, Brian Hanson, UD's resident glaciologist and chairperson of the geography department, will talk about glacier calving--the "birth” of icebergs.

Drawing on his own field research experiences, Hanson will speak about how icebergs come into being and address possible connections with climate warming in the polar regions.

In the neighboring gallery, Frederick “Fritz” Nelson, UD geography professor and co-chairperson of UD's William S. Carlson International Polar Year Events, will discuss several of the voyages of exploration represented in the historic maps and photographs of Poles Apart: Photography, Science and Polar Exploration.

The lecture is co-sponsored by University Museums, the William S. Carlson International Polar Year Events and the Department of Geography.

The exhibition Camille Seaman: The Last Iceberg appeared recently in the galleries of the National Academy of Sciences. Poles Apart has been adapted from Photographs from the Ends of the Earth, an exhibition that appeared at the Milwaukee Art Museum in 2007. The photographs, maps and paintings in Poles Apart appear courtesy of the American Geographical Society Library at the University of Wisconsin-Milwaukee and the American Geographical Society of New York City.
