Lecture on ocean acidification, March 27

Dr. Richard Zeebe, who is from the Department of Oceanography at the University of Hawaii-Manoa, will discuss ocean acidification targets, based on carbon cycle modeling efforts, at noon Friday, March 27, in Room 100 of the Geosciences Building. 500 Yates St. Global warming is in the news daily, but there is less awareness that the oceans have absorbed 40 percent of the carbon dioxide emitted by humans over the past two centuries. Moreover, ocean acidification is accelerating and expected to have detrimental consequences for a variety of marine organisms. If fluctuations of ocean chemistry beyond certain threshold values are to be avoided in the future, specific CO2 emission targets will be required. The presentation, which is free and open to the public, is part of the Frontiers in Science series of informal presentations on popular science topics sponsored by the College of Science. Brown bag lunches are welcome, and cookies and soft drinks will be provided. Call 817-272-3491 for more information.
