Secular variation in carbon uptake into the ocean crust
Description: Carbonate mineral precipitation in the upper oceanic crust during low-temperature, off-axis, hydrothermal circulation is investigated using new estimates of the bulk CO2 content of seven drill cores. In combination with previously published data these new data shows the CO2 content of the upper ~ 300 m of the crust is substantially higher in Cretaceous than in Cenozoic crust, and for any age of crust, there is substantially more CO2 in Atlantic than Pacific crust.
