Sediment geochemistry in freshwater seas: Lakes Superior and Malawi and comparisons with marine systems : This seminar is part of the Centre for Water Research seminar series. Other events...
Lakes are often referred to as “the test tubes of oceans”, but how much of the geochemical information is transferable between marine and freshwater systems? Should relationships such as those developed for the mineralization rates of marine organic carbon or marine rates of denitrification be applicable in freshwater? Can lakes help us quantify the processes in the Ocean?

This talk will describe sediment geochemistry in two very different large lakes: cold and well-oxygenated Lake Superior and tropical meromictic Lake Malawi. It will explore the geochemical cycling of carbon and nutrients and will compare the results to metrics developed previously in marine systems.

Bio,

Sergei Katsev is an Associate Professor at the University of Minnesota Duluth where he is a faculty member at the Large Lakes Observatory, the only institution dedicated to studies of large lakes worldwide.

He is a physicist and geochemist with interests in sediment and water-column geochemistry, lake hydrodynamics, and tropical limnology. His professional experiences include studies of marine coastal and deep sediments, the Great East African Lakes Kivu and Malawi, Indonesian Lake Matano, North American Lake Superior, and using lake systems as modern analogues for the ancient oceans of the Earth.

Professor Katsev is a 2014 UWA Gledden Visiting Fellow.

PS* This seminar is free and open to the public & no RSVP required.
