Lake Stewardship III

There are currently limited process-based models that can describe both the diffusive and ebullitive (bubbling) fluxes of greenhouse gases such as CO2 and CH4. Data from Lake Ormstrup and recent articles suggest that the latter in particular can be a very significant part of the total climate footprint from lakes, and that this can change radically when a lake shifts from turbid to clear water. In this project, we will develop a completely new module to the Water Ecosystems Tool (WET) model for greenhouse gases that can provide insight into the entire lake system's fluxes of CO2 and CH4. The module is developed and validated based on the unique data collected from Lake Ormstrup. The module will be used to quantify the effect of the restoration on greenhouse gases in the lake.
