The Biogeochemical Cycles Group aims to improve our understanding of how carbon and other elements cycle through the oceans and lakes and interact with climate
Global climate appears to be driven by how much CO2 there is in the atmosphere. This in turn depends partly on how carbon and other important biogeochemical elements behave within and at the boundaries of the oceans and large lakes. The behavior is governed by physics (e.g., circulation and stratification), chemistry (carbon speciation in seawater), biology (photosynthesis and organic matter decomposition), and geology (weathering and sedimentation). The Biogeochemical Cycles Group at the University of Minnesota uses numerical models and data analysis to quantitatively characterize the behavior of carbon in the oceans and lakes over various time scales. |
