Retired Coast Guard captain Dr. Lawson Brigham, a specialist in polar oceanography and ice navigation, is a veteran passage maker on icebreakers. Dr. Brigham will discuss navigating the Arctic and how it will change drastically in the early 21st century.
A lecture and slide show will be held Jan. 29 at the Shelter Island Library located on Route 114 in The Center, Shelter Island, N.Y. Refreshments will be served.
Warming of the Arctic, and with it increased circumpolar transportation, will pose new international challenges and create special environmental dangers. Climate-change expert Brigham will discuss this and more. Dr. Brigham will answer questions from the audience. Brigham will show a slide show of arctic conditions and ice breakers at work during transit of this difficult new trade route.
Brigham is a native Shelter Islander living in Alaska, where he is the professor of geography and arctic policy at the University of Alaska-Fairbanks.
