本研究於2002年7月利用海研一號(OR1-650)航次搜集黑潮流域的位溫、鹽度、pH值、及海水總二氧化碳量等資料，來探討夏季時臺灣東南方之黑潮流域是否受南海水影響、海水總二氧化碳之輸入機制、人為二氧化碳的穿透深度、與大氣二氧化碳的 “源”“匯”關係等。
由溫鹽資料顯示，在124°E到122.30°E間，海域水深350∼1350公尺處存在一中層水之界面，界面以東為具有鹽度極小值(約為34.18)的西菲律賓海中層水，界面以西則是與南海水混合的水團。南海水流出呂宋海峽後，於台灣島南端與121°25’ E 間，緊貼台灣東側海面，順黑潮北上並沿途混合，於122°E, 22°N處深度可及1250公尺。
黑潮流域深層水在水團移動過程中，增加的總二氧化碳量有23%來自生物殼體溶解所提供，其餘77%則來自有機質分解。經由Chen et al.(1986) 的公式計算，得知人為二氧化碳在此海域的穿透深度約為1200公尺。此外，黑潮流域表水的逸壓二氧化碳(fCO2)平均值為350±7μatm，與當時大氣二氧化碳的分壓(360μatm)相近，顯示在夏季時與大氣二氧化碳幾達平衡。

In order to understand the input of South China Sea Water (SCSW) onto the Kuroshio and the distributions of carbonate parameters in Kuroshio Water (KW), the temperature, salinity, pH and TCO2 were measured for the seawater samples collected from the Kuroshio regime off eastern Taiwan during the cruise ORI 650 in July 2002.
The distributions of temperature and salinity show that a front existed approximately along 123.5ºE, which separated the influenced KW by SCSW from typical KW. East of this front the water is characterized by temperature and salinity of KW, while west of it the water was mainly a mixture of the SCSW and the KW. After flowing out from the Luson Straint, the SCSW deflected northward along the east cost of Taiwan, and continuously mixed with the KW. The mixing of SCSW with KW could be traced northward as far as 22ºN and reach as deep as 1250m.
Based on the measured carbonate data, the calculated IC/OC ratio ranges from 22% to 23% in the deep water of the Kuroshio region. Additionally, the penetration depth of anthropogenic CO2 was estimated to be about 1200m by using Chen’s equation (Chen et al., 1986). Furthermore, the difference of pCO2 between atmosphere and surface seawater was evaluated to be about -5matm, indicating that the surface water in the study area was nearly saturated with pCO2 during the sampling period.
