Hans-Jürgen Brumsack, a professor at the University of Oldenburg in Germany and a former postdoctoral researcher at Scripps Institution of Oceanography at the University of California, San Diego, will deliver a lecture on the history of the Black Sea based on its sediments.
The presentation, to be held in the Sumner Auditorium on the Scripps Oceanography campus on Monday, is the Tsaihwa J. Chow Distinguished Lecture in Ocean Chemistry for 2012. Brumsack’s talk is entitled “Trace metal geochemistry of modern anoxic sediments: The Black Sea example.”
The Black Sea is distinguished by euxinic deep waters, which are delivered from the relatively salty Mediterranean. In his research, Brumsack has developed a geochemical record combining multiple sediment cores collected from the Black Sea to generate a single composite geochemical core log. His analysis of trace elements, iron, and other sediment components led to the creation of a reference archive to help understand exchanges between the Black Sea and neighboring seas and the paleoenvironmental evolution of its basin.
The presentation, which is free and open to the public, will begin at 3 p.m. at 8602 La Jolla Shores Drive. The lecture is named for Dr. Tsaihwa J. Chow, a geochemist with a long association with Scripps who died in 2006.
