Lecture Summary:

Arctic sea ice has repeatedly made headline news in recent years for dramatic summertime losses leaving vast new areas of open water north of Alaska. In this presentation, we will examine the ongoing retreat of sea ice and explore the measurements and observations behind the news stories. We will look at the latest data from ice buoys to see how the ice is regrowing since last summer's record-breaking retreat and we will compare computer model predictions of the future state of the Arctic Ocean. However, despite some predictions of virtually ice-free summers in the Arctic within the next few years, sea ice will continue to play a role in the lives of Alaskans during winter for many years to come. Drawing on experiences from different coastal communities, we will attempt to delve into the meaning of ice for those who live, work and travel in the North and consider some of the challenges and opportunities presented by an ice-diminished Arctic.

Presenter Biography:

Dr. Andy Mahoney is a Research Assistant Professor of Geophysics at the University of Alaska Fairbanks. His broad field of expertise is sea ice geophysics and his research interests encompass climate change, coastal dynamics, ice-ocean interaction and the relationship between humans and sea ice. He has spent 12 years studying sea ice in the Arctic and Antarctic using instruments from tape measures to satellites, but some of his most memorable lessons come from trips over the ice with local experts.
