New experiments suggest that nonbiological processes alone may not account for decreased magnetization at oil spill site

In August 1979, an oil pipeline burst near Bemidji, Minn., spraying 1.7 million liters of crude oil onto the ground. Following cleanup, 400,000 liters that had seeped into sediments still remained. Recognizing a unique opportunity, research groups began to study the site to gain new insights into the long-term dynamics of oil spills.
