Reduced ventilation and enhanced magnitude of the deep Pacific carbon pool during the last glacial period
It has been proposed that the ventilation of the deep Pacific carbon pool was not significantly reduced during the last glacial period, posing a problem for canonical theories of glacial–interglacialExpand
