本研究は、南シナ海北部の粒子状有機炭素（POC）と植物プランクトン炭素（C phy）の表面濃度を、地域調整を施した衛星リモートセンシングにより評価した。現場観測との比較では、POCで±28.5%、C phyで±37.0%の不確実性を示した。季節変動や沿岸域での増加、真珠川プルームや台湾灘の湧昇域での高濃度が確認され、海洋炭素循環の理解向上に寄与する。
English
This study assessed surface concentrations of particulate organic carbon (POC) and phytoplankton carbon (C phy) in the northern South China Sea using regionally tuned satellite remote sensing. Match-up comparisons showed uncertainties of ±28.5% for POC and ±37.0% for C phy. Seasonal and coastal variations, including elevated values along the Pearl River plume and Taiwan Bank upwelling, were observed, contributing to improved understanding of ocean carbon cycles.

📄 Abstract（原文）
Surface concentrations of particulate organic carbon (POC) and phytoplankton carbon (C phy ) in the northern South China Sea (NSCS) have been assessed successfully by remote sensing with appropriate regional tuning. Match-up comparisons between satellite derivations and field observations showed uncertainties of ± 28.5% for POC and ± 37.0% for C phy . The satellite-derived climatological distributions are consistent with previous reports. In the open NSCS where phytoplankton growth is controlled primarily by the convective overturn, both POC and C phy are higher in winter, associating with the effect of stronger northeast monsoons and surface cooling, than in summer, when surface heating and weaker southwest monsoons strengthen vertical stratification. Toward the coasts, because of terrestrial inputs, POC and C phy increase, varying by one order of magnitude. Particularly, they are prominently enhanced along the Pearl River plume, which may be extensive to the middle shelf in the summer according to high river discharge and northeastward coastal currents. Elevated POC and C phy are also found in the waters around the Taiwan Bank where upwelling occurs year round. Similar approaches on the remotely sensed POC and C phy may be applicable to other shelf-seas in order to improve our understanding in ocean carbon cycle.
