Abstract
Calcium concentrations in profiles from the western boundary region of the South Pacific were measured by a modified method of J.B. Pate and R.J. Robinson. The calcium content increases with depth from salinity minimum to benthic front, and then decreases slightly to the Antarctic Bottom Water. The calcium content was found to be closely related to carbonate alkalinity. The relation is expressed by the equation:(Ca) = 9.1497 + 0.5260 × (C.A.) where (C.A.) is carbonate alkalinity in meq/kg, and (Ca) is calcium content in mmole/kg. The slope, 0.5260, is consistent with the theoretical value predicted by the dissolution of calcium carbonate within the experimental error.
