Uncertainty in the of the transfer velocity of air-sea fluxes contributes to the discrepancy between estimates of budgets for trace gases. Measurement of fluxes with micrometeorological methods can provide a better understanding of transfer velocities. Much attention has been paid to the derivation of the transfer velocity from Eddy Correlation (EC) flux measurements of CO2 (Jacobs et al., 1999; McGillis et al., 1999; Wanninkhof and McGillis 1999). The application of micrometeorological techniques for the measurement of DMS fluxes is rather new. So far, only the Gradient Flux technique has been applied for this purpose (Baart et al., 1994; Putaud and Nguyen, 1996). The data scatter reported in these gas exchange studies leaves room to question the accuracy of the derived gas transfer velocities. Most of these studies focused on the measurement of a gas using a single system. The simultaneous measurement of the flux with different systems and of different gases could resolve these questions. We will present results from experiments during which we measured fluxes by the Gradient and Relaxed Eddy Accumulation techniques. These experiments are among the first in which DMS fluxes are measured by micrometeorological techniques.
