Hard-rock story

Oregon State University Professor Anthony Koppers and Toshitsugu Yamazaki of the Geological Society of Japan were co-leaders of the latest cruise conducted under the auspices of the International Ocean Drilling Program (IODP). Their target:  the Louisville Seamount Trail — a 2,600-mile-long line of underwater mountains in the South Pacific — where they hoped to learn more about the geophysical processes that produce such features as the Hawaiian Islands or the stretch of ancient volcanoes between the Oregon Cascades and Yellowstone National Park.
