You can find pre-prints, reprints and abstracts of of our papers on these topics here . It is soluble and has been invading the oceans, marking waters which have recently been near the surface. You can see an animation of the invasion of CFC-11 into the deep North Atlantic in one particular configuration of the MIT ocean circulation model. The finer resolution model shows significant ventilation of the western subtropical thermocline due to mesoscale eddy stirring. Comparing model simulations of ocean tracers with observed data can inform us about the veracity of our ocean circulation models.
Comparisons show significant differences between models and data, and between the different models.
Interannual Variability of Air-Sea Gas Fluxes. We use numerical models of ocean circulation and biogeochemistry to examine the possible effect of interannual changes in meteorological forcing and upper ocean circulation on the fluxes of carbon dioxide and oxygen between the ocean and atmosphere. In an earlier, regional study of the North Atlantic basin, we found a significant interannual air-sea flux of oxygen largely driven by changes in the depth of winter mixing in subpolar regions. Below the surface mixed-layer, oxygen is depleted by the remineralization of sinking organic matter. Each winter, this oxygen depleted layer is accessed by deep mixing, reducing the surface oxygen partial pressure and driving an air-sea flux of oxygen.
