Ocean Acidification From Space
About Our Speaker –Dwight Gledhill, Deputy Director, NOAA Ocean Acidification Program

Space-based observations provide synoptic coverage of surface ocean temperature, winds, sea surface height, and color useful to a wide range of oceanographic applications. Approaches to apply these observations to infer changes in sea surface ocean chemistry in response to ocean acidification have been demonstrated in recent years. The methods generally adopt the use of regionally specific empirical algorithms derived from ship measurements applied to remotely sensed observables. The application of remote sensing to synoptically upscale in--situ observations is important for exploring regional to basin--wide trends in ocean acidification on seasonal to interannual time scales. This presentation will survey the different projects being undertaken by NOAA's Ocean Acidification Program, focusing in the ones where satellite products are currently being adopted or would offer considerable benefit. Synergies and potential collaborations with NASA projects will also be discussed. |
| About the Talk Dr. Gledhill is the Deputy Director of NOAA’s Ocean Acidification Program office in Silver Spring, MD. The program was created in 2011 in response to the Federal Ocean Acidification Research & Monitoring Act (2009) to advance ocean acidification science in accordance with the Strategic Plan for Federal Research and Monitoring of Ocean Acidification. The program works to improve the nation’s understanding of the risk posed by ocean acidification to the marine environment and dependent human communities. Dr. Gledhill serves as a member of several interagency working groups related to ocean acidification and carbon cycling and is a member of the Northeast Coastal Acidification Network. Formally trained as a carbonate geochemist, Dr. Gledhill was an associate scientist with the University of Miami Cooperative Institute of Marine & Atmospheric Sciences (CIMAS) where he advanced research to better understand the process of ocean acidification within coral reef ecosystems. He was instrumental in establishing two long--term monitoring stations: in La Parguera, Puerto Rico and another within the Florida Keys National Marine Sanctuary. He also developed one of the first satellite--based ocean acidification products to better map the chemical changes unfolding across Greater Caribbean Region. Gledhill received his M.S. and Ph.D. from the Department of Oceanography at Texas A&M University in 2005 where he primarily investigated carbonate mineral kinetics in complex electrolyte solutions as well the sediment biogeochemistry associated with methane clathrates in the Northern Gulf of Mexico. |
