This study uses the decay of ^(40)K to ^(40)Ca to investigate the contributions of weathering and hydrothermal fluxes in the oceanic Ca budget. Because of its high K/Ca ratio, the silicate upper crust delivers radiogenic Ca to the oceans, while hydrothermal reactions deliver unradiogenic Ca from the mantle.
