Short summary
Extracting benthic oxygen fluxes from eddy covariance data measured in the presence of wave motions requires careful consideration of the temporal alignment of the vertical velocity and the oxygen concentration. We show that substantial errors in flux estimates can arise if these two variables are not aligned correctly in time. Due to the limited time response of all oxygen sensors used today, such a misalignment cannot be entirely avoided. We finally propose a new correction for this problem.
