theoretical prediction of the diffusion model for a film covered surface and
a surface renewal model in case of a clean and wavy interface.
The transport of heat as is insensitive to bubble-mediated gas transfer,
i.e., it measures the transfer rate of a gas with high solubility. In conjunc-
tion with measurement of other trace gases this feature might allow distin-
guishing between the different transport mechanisms governing air-water
gas transfer.
Using heat as a proxy tracer for gases not only delivers the transfer coef-
ficient at high spatial and temporal resolution but also gives direct insight
into the spatial structure of near surface turbulence enabling detailed inves-
tigations of the influence of surface chemical enrichments on the gas trans-
fer velocity and the turbulent transport mechanisms.
