One of the nation’s most important repositories of oceanic sediment cores, located at Oregon State University, will more than double in size later this year when the university assumes stewardship of a collection of sediment cores taken from the Southern Ocean around Antarctica. OSU has received a pair of grants from the National Science Foundation to assume the curatorial stewardship of the Antarctic and Southern Ocean National Collection of Rock and Sediment Cores, housed at Florida State University since the mid-1960s. Oregon State will house the expanded collection in a sophisticated new facility located just off-campus. NSF manages the U.S. Antarctic Program, whose logistical support and awards to researchers allowed many of the cores to be obtained. The OSU Marine and Geology Repository will be available to scientists around the world to study the sediment cores, which provide evidence of the Earth’s climate over the past millions of years, oceanic conditions, the history of the magnetic field, plate tectonics, seismic and volcanic events, ice ages and interglacial periods, and even the origin of life.
