This research is oriented to the development of a                       deliberate tracer experiment to examine the relationship                        between gas exchange rate and wind speed over the ocean.  Such                  a relationship will greatly facilitate estimation of gas fluxes                 of geochemically important gases such as carbon dioxide and                     oxygen on a global basis.                                                               The preliminary work will include development and testing               of non-volatile tracer which will be used in conjunction with                   the man-made volatile tracer, sulfur hexaflouride (SF6), in                     ocean experiments.  Wind tunnel tests will compare the ratio of                 gas exchange coefficients of SF6, carbon dioxide, radon,                        methane, and helium at different wind speeds so the exchange                    coefficient of SF6 obtained in the ocean can be used to                         determine the fluxes of these gases.  The non-volatile /                        volatile tracer combination will be first applied in a lake                     experiment to test sampling and analysis equipment and to                       ascertain the conservative behaviour of the non-volatile                        tracer.  The proposed research is an important part of the                      implementation of the Global Ocean Flux Study, GOFS, since gas                  exchange is a boundary condition for biogeochemical cycles                      involving gaseous compounds.
