Chao Lei (Petrophysics [Physical Properties] Specialist, China University of Geosciences, China) examines the working half of the core, which has been split. The working half is the area where samples can be removed if necessary for testing. The other half of the split section is called the archive half. It is photographed and eventually stored in its pristine state as a long-term resource for the scientific community of the future. (Credit: William Crawford, IODP JRSO) [Photo ID: exp367_161]
