The National Science Foundation awarded Oregon State University $4.6 million in grants to continue operating the Marine and Geology Repository, one of the nation’s largest repositories of oceanic sediment cores, for the next five years.

Funds will expand access to more than 22 miles of oceanic sediment cores and tens of thousands of marine rock specimens that reveal Earth’s history and document changes in climate, biology, volcanic and seismic activity, meteorite interactions and more.
