LEWISBURG, Pa. — Ken Macdonald will give the talk, "10,000 Leagues Under the Sea: Deep Dives to Explore the Underwater Volcanoes of the Global Mid-Ocean Ridges," Tuesday, April 19, at 7 p.m. in the Art Building Lecture Hall (Room 201) at Bucknell University.
The talk, which is free and open to the public, is sponsored by Ridge 2000, the Bucknell department of geology and the Bucknell Lectureship Committee.
Professor of marine geophysics at the University of California in Santa Barbara, Macdonald has led more than 20 expeditions to mid-ocean ridges.
While at Bucknell, he also will speak to faculty and students with an interest in mid-ocean ridge science including geophysics, geology, geochemistry, biology, microbiology, oceanography, and ecology.
His class lecture, "Linkages Between Tectonics, Volcanism, Hydrothermal Activity, Vent Animals, and Segmentation on Mid-Ocean Ridges," will be presented Wednesday, April 20, at 7 p.m. in the Gardner Lecture Hall of the Dana Engineering Building.
Macdonald is a Ridge 2000 Distinguished Lecturer. The Ridge 2000 outreach program is sponsored by the National Science Foundation. Ridge 2000 is an interdisciplinary research program to explore Earth's oceanic spreading ridge system as an integrated whole, including tectonics, volcanism, petrology, geochemistry, hydrothermal venting, subseafloor and seafloor microorganisms, vent faunas, ecosystems, and the overlying oceans.
