The College of the Environment and the School of Oceanography invite you a lecture featuring renowned ocean chemist and Walker-Ames Scholar, Peter Brewer. Hear him discuss the implications a changing climate has on the oceans in his talk titled: Common sense chemistry and a true tipping point for climate right off our shores.
About the Lecture:
Warming of the oceans is reducing oxygen content with important consequences for the survival of marine life. The implications of this can be far-reaching, but the basic problem can be described and understood quite simply: oxygen is less soluble in warm water, and microbes decompose organic matter faster at higher temperatures. While the basic facts are clear, it is only recently that scientists have begun to understand the scale of this problem. In some areas, such as off the West Coast of the U.S., the effects can be so dramatic that toxic hydrogen sulfide gas is likely to appear there for the first time in tens of millions of years.
Brewer will describe and quantify the problem, discuss the fragile chemical buffer that now exists, and show video footage illustrating the cascade of processes unleashed by decreased oxygen levels, transforming viable fisheries into bacterial ghost towns.
When: Tuesday, April 30, 2013 at 6:30 p.m.
Where: School of Aquatic and Fishery Sciences Auditorium, Seattle Campus
Cost: Free and open to the public. Advance registration is requested.
About the Speaker:
Peter Brewer is an ocean chemist, and Senior Scientist, at the Monterey Bay Aquarium Research Institute (MBARI). At MBARI he served as President and Chief Executive Officer from 1991-1996, completing major laboratory and SWATH ship construction programs and doubling the size of the Institution, before returning to full time research. His research interests are broad, and include the ocean geochemistry of the greenhouse gases. He has devised novel techniques both for measuring and for extracting the oceanic signatures of global change. At MBARI his current interests include the geochemistry of gas hydrates, the bio-geochemical impacts of the growing oceanic fossil fuel CO2 signal and the multiple impacts of ocean acidification, and the development of in situ laser Raman spectrometry techniques for real-time measurement in the deep-sea.
This lecture is sponsored by the College of the Environment, School of Oceanography, UW Program on Climate Change, JISAO , Friday Harbor Laboratories and IPOC
