Denis Gilbert

Dr. Denis Gilbert is a Research Scientist with the Department of Fisheries and Oceans Canada at the Maurice-Lamontagne Institute in Mont-Joli, Québec. Dr. Gilbert received his B.Sc. in Physics from the University of Québec at Chicoutimi and his Ph.D. from Dalhousie University in Halifax, Nova Scotia. His research has focused on a variety of scientific problems, from the study of internal wave dynamics to ocean climate variability, marine fisheries and ocean chemistry. He served on the US EPA (United States Environmental Protection Agency) Science Advisory Board's Hypoxia Advisory Panel, charged with examining the causes and impacts of hypoxia in the northern Gulf of Mexico, as well as the sources, transport and fate of nutrients in the Mississippi-Atchafalaya River Basin. On behalf of the international Scientific Committee on Oceanic Research (SCOR), he was leader of Working Group 128 on natural and human-induced hypoxia and consequences for coastal areas. Today, he will talk to us about oxygen in the ocean, discussing how eutrophication and climate variability and change may both contribute to the generally decreasing oxygen trends observed in the global ocean.
