Four scientists who used data from the seafloor near Alaska to study topics ranging from earthquakes to economic rights will present this year's Chapman Seminars at the University of Alaska Fairbanks.

The presentations will take place from 3:30 to 5:10 p.m. each Wednesday and Friday from Feb. 19 through March 14. Wednesday seminars will take place in the Elvey Auditorium, Room 214 of the Elvey Building, and Friday seminars will take place in the Pearl Berry Boyd Hall, Room 201 of the Reichardt Building. The seminars are free and open to the public. UAF students may take the seminars for credit.

The presenters include Donna Shillington of the Lamont-Doherty Earth Observatory at Columbia University; Professor Bernie Coakley of UAF’s Geology and Geophysics Department; Associate Professor John Jaeger of the University of Florida Gainesville’s Department of Geological Sciences; and Ginger Barth of the U.S. Geological Survey in California.

The scientists spent the summers of 2011 and 2012 collecting data from the R/V Marcus G. Langseth. The vessel specializes in creating two- and three-dimensional maps of the seafloor and the structures miles beneath it. The National Science Foundation owns the ship and the Lamont-Doherty observatory operates it.

The scientists collected and analyzed seismic data near Alaska to study mega earthquakes, the paleoclimate, the Arctic Ocean’s formation and how far the United States can claim exclusive economic rights off Alaska’s coastline.

David Scholl, a former USGS geologist who holds a Sydney Chapman Endowed Chair in Physical Sciences in the UAF College of Natural Science and Mathematics, organized the seminars.

The Chapman Seminars bring top scientists from around the world to share their expertise about different topics with the campus community.

The UAF College of Natural Science and Mathematics hosts the lectures.
