A carbonate geologist in the Department of Paleontology at the Smithsonian's National Museum of Natural History, studies the geology of mangrove ecosystems.
Ian (left) and his field assistants use a hydraulic-powered drill to core the Pleistocene limestone base of Twin Cays. This limestone was extensively recrystallized and could not be dated. It is thought to have been deposited during the last interglacial period and then subaerially exposed when sea level fell 79 thousand years ago.
