FRONTIERS OF SCIENCE LECTURE TUE, NOV. 8 "THE ARCTIC OCEAN'S SHRINKING ICE COVER" --- --- 7:30 PM ALINE W. SKAGGS BIOLOGY BLDG. (See map: http://www.map.utah.edu/index.html?find=82) FREE AND OPEN TO THE PUBLIC! NO TICKETS REQUIRED Hajo Eicken, a professor of geophysics at the University of Alaska Fairbanks, will discuss key factors that drive Arctic sea ice change an annual and decade-long timescales during a free public lecture on Nov. 8. In 2007, the loss of Arctic sea ice broke all previous records by early August – a month before the end of melt season – with a decline in Arctic sea ice minimum extent of roughly 400,000 square miles. For the first time in human memory, the Northwest Passage opened completely. In 2008 and 2009, Arctic sea ice minimum extent was greater than 2007, but did not return to the levels of previous years. How can we explain such changes and are they unique in Earth’s long-term history and recent past? What do declines in summer sea ice mean for Arctic residents, including walruses, polar bears and other animals that depend on the ice, as well as for human activities such as shipping or resource extraction? This event is free and open to the public! NO tickets are required. Arrive early for best seating. Click here for a campus map to the event: http://www.map.utah.edu/index.html?find=82.
