The OSU Coring & Dredging Facility provides marine geologic sampling services for NSF groups and investigators using the UNOLS fleet as well as the USCG ice breaker R/V Healy. Funding for these services to US NSF funded investigators is provided by Ship Facilities Program at NSF. The OSU coring gear is among the best available in the United States, including large-volume and small-volume piston corers (4″ ID x 18m and 2.5″ ID x 18m), box corers, kasten corers, and several multicorers and slow corers for undisturbed recovery of sediment-water interface. Seagoing technicians from the facility have operated coring and dredging gear on most UNOLS vessels.

Services are customized to fit your needs, and can include use of hardware, personnel, deck handling gear, refrigerated shipping vans, sample describing materials, and permanent archival in the OSU Marine Geology Repository.
