Coring for clues—
WHOI researchers Justin Ossolinski and Konrad Hughen extract corals in search of past climate data. Coral growth bands serve as a timescale going back hundreds of years, and coral skeleton chemistry reflects ocean conditions at the time the coral was alive.

On a remote coral reef off Woleai Atoll in Micronesia, WHOI research assistant Justin Ossolinski (left) and WHOI marine chemist Konrad Hughen drill cores from a colony of Porites lobata. In the foreground, sections of the core lie ready for labeling and transport to the surface. Corals add to their skeletons in layers, and this core reached 15 feet in length, representing more than 400 years of the corals growth. The snowy white cores, made of calcium carbonate, contain chemical clues to ocean conditions at the time they were made. Back at WHOI, Hughen and colleagues analyze coral cores from many oceans to reconstruct past climate changes in regions around the world. See Page 7.

Research assistant Justin Ossolinski (left) and marine chemist Konrad Hughen drill cores from a colony of the coral Porites lobata in the Federated States of Micronesia. In the foreground, sections of the core lie ready for labeling and transport to the surface. The snowy white cores, made of calcium carbonate, contain chemical clues to ocean conditions at the time they were made. Back at WHOI, Hughen and colleagues will analyze the cores to reconstruct past changes in climate in the western Pacific. This core reached 4.6 meters in length, representing more than 400 years of the corals growth.
