North Temperate Lakes Long Term Ecological Research studies the ecology of lakes as one of a network of sites established by the National Science Foundation. We are interested in how biophysical setting, climate, and changing land use and cover interact to shape lake characteristics and dynamics over time (past, present, future).
Our primary study sites include a set of seven northern Wisconsin and four southern Wisconsin lakes and their surrounding landscapes. The project, which started in 1981, is administered by the Center for Limnology at the University of Wisconsin-Madison.
Although streams are now recognized as important components of regional and global carbon budgets, patterns and controls of stream CO2 and CH4 budgets are poorly documented for most landscapes. One major question is: Do streams support their CO2 and CH4 emissions through internal processing or do terrestrial sources and groundwater provide most of the gas supply?
