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.
Estimating the flux of carbon dioxide (CO2) from lakes is important for understanding the role of these ecosystems in regional and global carbon budgets. The efflux of partially soluble gasses such as CO2 is controlled by near-surface turbulence. Lakes receive turbulent inputs across the air-water interface via two primary mechanisms: wind shear and negative buoyancy flux (convective cooling). We examined the relative importance of wind and convection in 42 temperate lakes from multiple countries that covered gradients in latitude, size, and water clarity.
