Xue Liang, Yu Weidong, Ning Chunlin, Wang Huiwu. Advances in Sea Surface Partial Pressure of CO 2 Time-Series Studies[J]. Advances in Earth Science, 2013, 28(8): 859-865.

The method of sea surface partial pressure of CO2 (pCO2) timeseries studies is simply summarized, and the advances in indentifying pCO2controlling processes, revealing interannual variability in pCO2, monitoring the influence of some climatic events on pCO2, and estimating airsea CO2 fluxes based on timeseries studies are reviewed in detail. Generally, pCO2 time-series studies are conducted by ship-based investigation and autonomous buoy CO2 measurement. Besides some qualitative observation of irregular and episodic events that influence pCO2, timeseries study could quantitively calculate separate contribution of various controlling processes to pCO2 variation, which is of importance for revealing pCO2 controlling mechanisms. Moreover, time-series studies on interannual time-scales show that human activities have caused the increase of sea surface pCO2. As well, El Nio and La Nina events could significantly influence sea surface pCO2 and air-sea CO2 fluxes. In addition, it is crucial to conduct time-series studies for improving the estimation of air-sea CO2 fluxes.
