Atmosphere-ocean heat and carbon dioxide (CO2) fluxes (plots) and vertical distributions of ocean temperature and dissolved inorganic carbon (DIC) (TO and tCO2; shades) in the Atlantic ocean (30°W): the first and third columns show the absolute magnitudes of the fluxes and system states (ocean temperature and DIC), and the second and fourth columns show the anomalies from the control run. The units are: W m−2 for ocean net heat flux (FH; negative means ocean uptake), °C for TO, gC m−2 year−1 for ocean net carbon flux (FC; negative means ocean uptake), and mmol m−3 for tCO2. Counter lines in panels show isopycnic surfaces with an interval of 0.5 σθ. The RAD2 × CO2 result by MIROC-ESM is used for the FH and TO analyses, and BGC2 × CO2 for FC and tCO2. All analyses were made based on 30 year averages and anomalies. Red, orange, and magenta arrows represent the anthropogenic C transport by the Antarctic intermediate water (AAIW), Antarctic bottom water (AABW), and North Atlantic deep water (NADW), respectively
