Summary

Alkalinity profiles in transoceanic sections at 43°S and 28°S based on samples collected on Eltanin cruises 28 and 29 are reported. A maximum in alkalinity is found at a depth of 2000 to 3500 meters. The western boundary is lower in alkalinity than the eastern part of the Pacific Basin. These patterns can be explained by a model of supply of low alkalinity water to the abyss via a western boundary current. As the initially low alkalinity water rises it dissolves sinking calcium carbonate tests, resulting in a maximum in alkalinity at intermediate depths.
