Carbon Dynamics on a Eutrophic LakeWhat 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 DynamicsHow 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! |
