Ocean ventilation refers to the movement of air and water in and out of the ocean. It helps distribute heat, oxygen, and nutrients throughout the ocean, creating a balanced and healthy environment for marine life. Full definition
These changes are everywhere consistent with the local changes in ocean ventilation as identified either by changes in density gradients or by changes in apparent CFC ages. (ipcc.ch)
The millennial (500-2000 year) time scale of deep ocean ventilation affects the time scale for natural CO2 change and thus the time scale for paleo global climate, ice sheet, and sea level changes, but this paleo millennial time scale should not be misinterpreted as the time scale for ice sheet response to a rapid large human - made climate forcing.

Changing westerly winds in the Southern Hemisphere have caused coherent changes in the southern ocean ventilation. (science.sciencemag.org)
