Nile and Yangtze Deltas: Dams and Damnation (G,S)

Daniel Jean Stanley is a Smithsonian Senior Oceanographer at the National Museum of Natural History in Washington, D.C., and an adjunct professor at several universities in North America, Europe, and China. His training is in geology, and his research has focused on Alpine and Mediterranean sedimentology and more recently, coastal geology of world deltas. His present work integrates Quaternary sea-level changes, modern delta evolution and geo-archaeology. He holds degrees from Cornell and Brown, and a D.Sc. from l'Ecole Nationale Superieure du Petrole et es Moteurs/Paris and Grenoble, France. He taught at Dalhousie University in Canada prior to his appointment at the Smithsonian 31 years ago. Dr. Stanley is an AAAS and GSA fellow, a frequent keynote speaker at international geological and environmental meetings, and has received the SEPM's Shephard Medal for Excellence in marine geology. His avocations include diving on archaeological sites and gardening.
