GED Scientist Plenary Speaker at SETAC Annual Meeting
Rick Greene of NHEERL's Gulf Ecology Division (GED) was invited to serve as a plenary speaker at the Society of Environmental Toxicology and Chemistry (SETAC) 30th Anniversary Meeting, November 19-23, 2009. SETAC is a nonprofit, international professional society comprised of individuals engaged in the study, analysis, and solution of environmental problems. The annual meetings, which typically draw 2,500 participants, are forums where scientists, managers, and other professionals exchange information and ideas for the development and use of multidisciplinary scientific principles and practices leading to sustainable environmental quality. Dr. Greene's plenary presentation, "Gulf of Mexico Hypoxia: Conceptual and Practical Implications," focused on EPA efforts to develop a modeling framework to address the hypoxia problem in the northern Gulf of Mexico and, in particular, to explore and establish defensible strategies for a nutrient load threshold. Dr. Greene is Chief of GED's Ecosystem Dynamics and Effects Branch, where he directs research to determine the effects of environmental stressors on coastal aquatic ecosystem structure and function in support of ecological criteria development. He also serves as the EPA lead for Gulf of Mexico hypoxia monitoring and modeling research and for water quality research supporting nutrient criteria development in estuarine and coastal waters. Dr. Greene serves on numerous Federal/State science teams, advisory committees, and task forces, including the interagency Mississippi River/Gulf of Mexico Watershed Nutrients Task Force Coordinating Committee. He recently co-chaired the symposium "Hypoxia in the Northern Gulf of Mexico: Assessing the State of the Science," which was conducted as part of the Mississippi River/Gulf of Mexico Watershed Nutrients Task Force's reassessment of the 2001 Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico.
