Carbon Dynamics on a Eutrophic Lake
What is the carbon budget of a eutrophic lake? What factors control organic carbon cycling during the open-water season?
We collected weekly data on carbon loads, exports, and internal processes on Lake Mendota in Madison, WI. Lake Mendota is a highly productive, eutrophic lake often plagued by algal blooms and poor water quality. Exploring the factors controlling carbon dynamics may improve our ability to predict and mitigate harmful algal blooms.
Carbon Dioxide & Methane Dynamics
How much carbon is converted to carbon dioxide and methane in a eutrophic lake? Do eutrophic lakes exhibit an enhanced greenhouse effect?
We collected weekly dissolved carbon dioxide and methane samples on Lake Mendota in Madison, WI. All samples were analyzed using a gas chromatograph with a flame ionization detector. We also deployed ebullition traps to capture bubbling events. Any surface in Lake Mendota is a surface for algae growth - including methane traps!
