The Fossils Forests of Antarctica: What Do They Mean for the Future of the Polaris Regions?
Dr. Erik Gulbranson, Visiting Assistant Professor of Geology
Antarctica in the present is ice-covered, with about 1% of the land area exposed above glacial ice. Terrestrial ecosystems are sparse and no true forested ecosystem currently exists at the southern polar region. The geologic past of Antarctica, however, reveals a much richer history of terrestrial ecosystems with numerous examples of forests having developed, from ~14 million years ago to ~300 million years ago. Dr. Gulbranson will present an overview of these forested ecosystems; how they discover them; what they have learned about them; and how these ecosystems inform us about the significance of life on the land near the Earth's polar regions.
