Topic: Harmful Algal Blooms
Title: Harmful Algal Blooms: Causes and Impacts
Description: The presentation will describe the different kinds of Harmful Algal Blooms, their impacts on human health, coastal economies, and ecosystems, and the factors, human and natural, that cause them.
Guest Expert Bio: Quay Dortch is the Coordinator for the Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) Program in the National Oceanographic and Atmospheric Administration (NOAA). ECOHAB provides funding for research on the causes and impacts of harmful algal blooms (HABs). She led the effort to establish the new NOAA Prevention, Control, and Mitigation of Harmful Algal Blooms (PCM HAB) Program. As the NOAA Co-Chair of the HABS and Hypoxia Subcommittee of the Interagency Working Group on HABs, Hypoxia, and Human Health, she led implementation of the requirements of the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA), reauthorized by the U.S. Congress in 2004. She is also involved with NOAA and appropriate Congressional committees in the process to draft the next reauthorization of HABHRCA.
Dortch received her Ph.D. from the University of Washington in Oceanography, M.S. in Chemistry from Indiana University, and B.A. in Chemistry from Randolph-Macon Woman’s College. She held research positions at the University of Washington and Bigelow Laboratory for Ocean Sciences before joining the faculty at Louisiana Universities Marine Consortium from 1986-2002. Her research examined nutrient utilization by marine phytoplankton, focusing most recently on studies of HABs, hypoxia and eutrophication in Louisiana coastal waters, especially those influenced by the Mississippi River. Dr. Dortch is the author or co-author of approximately 90 scientific papers as well as recent interagency reports assessing the causes and impacts of HABs and proposing plans for improving research and response to HABs.
