英文摘要	The Southern Ocean plays a key role in modulating the global carbon cycle, but the size and even the sign of the global ocean flux terms of the atmospheric burden of man-made CO2 are still uncertain. This is in part due to the lack of measurements in this remote region of the world ocean. This project continues a multi-year time series of shipboard chemical measurements in the Drake Passage to detect changes in the ocean carbon cycle and to improve the understanding of mechanisms driving natural variability and long-term change in the Southern Ocean. This project is a continuation of collection of upper ocean measurements of the underway surface partial pressure of carbon dioxide (pCO2), using frequent ferry crossings of the Drake Passage by the RV/AS LMGould, the USAP supply ship. Overall, more than 200 transects over the past decade (since 2002) have now been accumulated of pCO2 profiles, along with discrete samples for other parameters of interest in studying the ocean carbonate system such as total CO2 (TCO2) values, isotopic (13C/12C and 14C/12C) ratios in surface TCO2. The Drake Passage data are made readily available to the international science community and serve as both validation and constraints of remotely sensed observations and numerical coupled earth systems models.
