Freshwater Colloquium: Anthropogenic impacts in large-lake carbon cycling
Liz Minor will present “Anthropogenic impacts in large-lake carbon cycling” as part of the School of Freshwater Sciences Spring colloquium.
Liz Minor is a professor in the Department of Chemistry and Biochemistry and at the Large Lakes Observatory at the University of Minnesota Duluth. She received her B.S. in Chemistry from The College of William and Mary in Virginia and her Ph.D. in Marine Chemistry and Geochemistry from the Massachusetts Institute of Technology/Woods Hole Oceanographic Institution Joint Program in Oceanography and Ocean Engineering. Her research group studies carbon cycling in lake, river, and ocean water columns across daily to decadal scales. This includes work on lake acidification and alkalinity trends and studies of organic matter in aquatic systems, including that new anthropogenic organic matter, plastics. Support for her work has come from the US National Science Foundation, the Minnesota Pollution Control Agency, the State of Minnesota Environmental and Natural Resources Trust Fund, Minnesota Sea Grant, the ACS Petroleum Research Fund, and the US National Park System.
Humans have impacted large-lake carbon cycles in several ways, including shifting atmospheric exchanges of inorganic carbon, the effects of erosion and chemical weathering, inputs of nutrients, and inputs of anthropogenic carbon species such as microplastics. This talk will discuss anthropogenic impacts on Lake Superior carbon cycling, with a focus on microplastics and inorganic carbon inputs.
The Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Most talks will involve the theme of Emerging Contaminants in Aquatic Environments. Snacks will be available prior to the talk. Please join us!
This presentation is open to students, faculty, staff, alumni and the public.
Spring 2025 Colloquium Series schedule. The Colloquium series creates a platform where students, faculty, and scientists discuss emergent issues related to freshwater science research. Invited speakers present specific topics of their research, as well as policy, commercial, and industrial experiences. Everyone is welcome.
