Monitoring the pulse of a lake
Recent evidence from lakes around the world has changed scientists view of the role lakes play in climate change and the global carbon cycle. That role was long assumed to be insignificant, because lakes occupy only a very small proportion of the earths surface. But we now know that the cumulative uptake and release of carbon by lakes is much greater than their size would suggest.
The biological processes by which lakes take up, process, and release carbon show a pronounced rhythm the pulse of a lake. Rates of these processes change rapidly over the course of a day (Figure 1), complicating efforts to estimate how much carbon a lake takes up and releases each day, month, and year. Yet accurate estimates are essential in determining whether lakes tend to reduce or increase atmospheric levels of heat-trapping greenhouse gases like carbon dioxide.
In an ongoing project funded by U.S. EPAs Great Lakes Restoration Initiative, a team of AWRI researchers and students is developing improved approaches to estimating the dynamic rates of carbon uptake and release by lake ecosystems using mechanistic models of lake metabolism and data produced by AWRIs Muskegon Lake Buoy Observatory ( www.gvsu.edu/wri/buoy/). The AWRI team includes Dr. Bopi Biddanda, Scott Kendall, and Dr. Jim McNair, as well as graduate students Leon Gereaux and Meagan Sesselmann and undergraduate student Anthony Weinke.
