signi

function has been studied inadequately.
There are only some experimental estimates (Alekseev et al. 1992). Of course, a lot

fl
uxes on the

can
be considered as mutually exclusive. That is, a valve is supposed to exist on the
atmosphere-ocean border. Its switching is determined by the pH parameter. A
critical level of pH is about 8.11. At pH

fl

8.11 the ocean assimilates CO
2
, and at
pH > 8.11 the ocean emits CO
2
.
