通过对历史氧资料的分析，为中国南海和太平洋之间的水交换提供了证据。在吕宋海峡附近，在700~1500 rn(中层)之间，太平洋一侧的海水溶解氧浓度低于南海一侧，而在700 rn以上(上层)和1500 rn以下(深层)，情况则相反。证据表明，水在中层离开南海，但在上层和深层都从太平洋进入南海。支持了吕宋海峡输运在垂直方向上具有夹层结构的推测。在南海盆地内，氧的分布显示出广泛的垂直新流，包括中间层的上升流和深层的下降流。
An analysis of historical oxygen data provides evidence on the water exchange between the South China Sea(SCS)and the Pacific Ocean(PO).In the vicinity of the Luzon Strait(LS),the dissolved oxygen concentration of sea water is found to be lower on the Pacific side than on the SCS side at depths between 700 and 1500 rn(intermediate layer),while the situation is reversed above 700 rn(upper layer)and below 1 500 rn(deep layer).The evidence suggests that water exits the SCS in the intermediate layer but enters it from the Pacific in both the upper and the deep layers,supporting the earlier speculation that the Luzon Strait transport has a sandwiched structure in the vertical.Within the SCS basin,the oxygen distribution indicates widespread vertical rnovernent,including the upwelling in the intermediate layer and the downwelling in the deep layer.
