The data indicate that in the Atlantic Ocean the excess CO sub(2) has penetrated through the entire water column in the northern North Atlantic, to roughly 1,000 m in the equatorial region, to over 1,800 m around 40 degree S, and to less than 200 m around 65 degree S, but penetration deepens again around the Antarctic Continent. The penetration in the Pacific Ocean is generally shallower than in the Atlantic Ocean, with the deepest penetration found in the northwest North Pacific and in regions around 45 degree S. The shallowest penetration is found in the Eastern equatorial Pacific and in regions around 65 degree S. Depth of penetration of anthropogenic CO sub(2) appears to have been controlled by such factors as bottom water formation in the North Atlantic, upwelling in the Eastern Atlantic, the equatorial Pacific and near 65 degree S, and vertical mixing in western boundary areas.
