Figure F7. On the rig floor of the R/V JOIDES Resolution, Co-Chief Scientist Rick Murray; Integrated Ocean Drilling Program (IODP) Marine Laboratory Technicians Kristin Bronk and Thomas Gorgas, and Assistant Laboratory Officer Tim Bronk; Phil Christie and the Siem rig floor crew extrude core samples into opaque core bags for special analysis of optically stimulated luminescence (OSL). OSL, a technique for determining the age of marine sediment, requires that the core never be exposed to direct light. Cores were immediately carried to the catwalk for processing by IODP Marine Laboratory Technicians Emily Fisher, Gabe Matson, and Justin Skootsky.
