Storage and redistribution of anthropogenic CO₂ in the western North Pacific: The role of subtropical mode water transportation.

ABSTRACT: Oceanic uptake and storage of anthropogenic CO₂ (C_ANT) are regulated by ocean circulation and ventilation. To decipher the storage and redistribution of C_ANT in the western North Pacific, where a major C_ANT sink develops, we investigated the water column carbonate system, dissolved inorganic radiocarbon and ancillary parameters in May and August 2018, spanning the Kuroshio Extension (KE, 35-39 °N), Kuroshio Recirculation (KR, 27-35 °N) and subtropical (21-27 °N) zones. Water column C_ANT inventories were estimated to be 40.5 ± 1.1 mol m^-2 in the KR zone and 37.2 ± 0.9 mol m^-2 in the subtropical zone. In comparison with historical data obtained in 2005, relatively high rates of increase of the C_ANT invent
