Wind.

You’re totally right that there isn’t much vegetation there for turning CO2 into O2, but there also aren’t many critters there turning O2 into CO2 there either; in the end it all sort of evens out that the breathable oxygen doesn’t get locally depleted before wind and diffusion can bring enough fresh air back in.
