Pacific Corals and Climate

Pacific Corals and Climate

Brad Sampling

Similar to tree rings, long-lived corals hold climate records going back hundreds or thousands of years. In diving expeditions to several Pacific Ocean islands, Lamont-Doherty Earth Observatory paleoclimatologist and paleoceanographer Brad Linsley has collected cores that hold up to 500 years’ worth of climate information. In this photo, Linsley’s colleagues from Stanford University take a sample from coral in Ta’u, American Samoa.
