dc.description.abstractThis research uses TrOCA method in order to investigate anthropogenic CO2 distribution in the Indonesian Throughflow (ITF) regime as well as its relationship with water mass transport from Pasific Ocean to Indian Ocean, based on four parameters; TCO2 (dissolved inorganic carbon), TA (total alkalinity), O2 (oxygen), and θ (potential temperature). The calculated anthropogenic CO2 is generaly distributed in upper layer of thermocline from both oceans, with concentration of 20–50 μmol.kg-1. In the North Equatorial Current (NEC) station section (section P10N) of Pacific Ocean, the anthropogenic CO2 is mainly stratified in upper layer with maximum concentration of 50 μmol.kg-1 and founded near surface. The anthropogenic CO2 content in NEC will be transported to Mindanao Current (MC) regime which is an inflow for ITF. Two stations in MC regime showed a similar stratification of anthropogenic CO2 in upper layer with maximum concentration of about 50 μmol.kg-1. In the outlet of ITF, particularly station section along eastern Indian Ocean (section H_I10), the stratification is still found in upper layer with maximum concentration of 50 μmol.kg-1. In section H_I10 on the eastern of Indian Ocean, concentration along latitude and longitude line are higher than the stations in western of Pasific Ocean. The estimation of anthropogenik CO2 budget in outlet ITF is 40.43–73.38 Tg C y-1, higher than those observed in inlet ITF is 13.88–33.72 Tg C y-1. It means that the ITF region is responsible for this different. In station of Banda and Ombai Strait, a high accumulation anthropogenic CO2 was found between 20-71 μmol.kg-1 in the depth ranging from 5 to 200 m. In Banda station, this accumulation was probably due to water mass transport from Java Sea, resident time and acccumulation of water, whereas in Ombai Strait station, it was because of water mass transport from Java Sea and Pacific Ocean, and terrestrial run off.en
