The seawater fugacity of carbon dioxide (CO; fCO) was investigated over four seasons in the southeastern Yellow Sea (YS). The seasonal variation in sea surface temperature (SST)-normalized fCO in the study area was largely explained by sea surface concentrations of dissolved inorganic carbon modulated by the water column stability in association with biological carbon fixation and remineralization. Overall, our study area acted as a sink for atmospheric CO, absorbing a regional average of ~2.8 mmol C m day. This result contrasts sharply with the large CO effluxes reported in other parts of the YS, implying considerable spatiotemporal variations in fCO in this region. Since the YS is significantly influenced by human activity, our data will serve as a baseline to record the human impact on ocean carbon cycles in the future.
本研究调查了黄海东南部四个季节海水中二氧化碳（CO）的逸度（fCO）。研究区域的海水表面温度（SST）归一化 fCO 的季节性变化主要由水柱稳定性调节的海水中溶解无机碳浓度解释，与生物固碳和再矿化有关。总体而言，我们的研究区域是大气 CO 的汇，吸收了约 2.8mmolC m day 的区域平均值。这一结果与黄海其他地区报告的大量 CO 排放形成鲜明对比，表明该地区 fCO 的时空变化相当大。由于黄海受到人类活动的显著影响，我们的数据将作为未来记录人类活动对海洋碳循环影响的基线。
