OGRL scientist running tests on samples of water in the lab at Kansas Water Science Center.

During the symposium, participants could tour the facilities at Woods Hole Oceanographic Institution, such as this radiocarbon lab. Here scientists analyze the amount of radiocarbon in such material as coral or wood to help determine their age. Photo credit: Amy West, USGS Pacific Coastal and Marine Science Center
