This figure shows burial rate of organic matter in the ocean [Fbg,ocean], phosphorus, temperature, and pCO2 to the injection of CO2 estimated using the C–P biogeochemical model (a, b) and mantle-derived Os input estimated using the Os box model (c). a The duration of the input of CO2 is varied from 100 to 1000 kyr, and in b, the amount of CO2 input is varied from 0 to 1022 g CO2 (~2.7 × 105 GtC), during 400 kyr, which is the estimated maximum amount of CO2 released from OJP42. Data points in a and c represent the actual data from DSDP Site 463.
