What happens to the atmosphere when you suck all the oxygen out of the oceans?
Also, how long would it take for the oceans to reabsorb that oxygen? Do the current records follow these expectations?
Perhaps there are proxy signals? For example, there's ocean re-oxygenation faster (or slower?) than expected? Could a species that required more oxygen tip the scales?
