Lake-Atmosphere Gas Exchange in Lake Michigan

The goal of this research program is to determine the flux of CO2   and O2 between Lake Michigan and the atmosphere.  Lake Michigan is   an ideal system in which to conduct this study for several reasons:    1) Its nutrient budgets and general physical limnology are   relatively well known;  2) An instrumented buoy array is currently   being developed and deployed in the lake, which will provide a large   amount of supporting data on currents, thermal structure, and   plankton dynamics;  3) There are commercial vessels currently   operating on the lake that can be used to acquire data with a high   degree of spatio-temporal resolution.      The primary research objectives are:  1) To develop a method   that allows for collection of lake surface and atmospheric   concentrations of CO2 and O2 with high spatio-temporal resolution;    2) To implement this method on Lake Michigan in order to quantify   lake-atmosphere gas exchange on a daily basis, with the goal of   determining the net annual lake-atmosphere exchange and   understanding how short-term fluctuations in this exchange are   driven by physical conditions (water temperature, lake   stratification, upwelling, irradiance) and biogeochemical conditions   (nutrient concentrations, phytoplankton abundance).
