项目摘要
We established an international ocean observation network in the Australian-Antarctic Basin, Southern Ocean, with implementing stable oxygen isotope measurements as the standard method and compared the results with the previous hydrographic observations. Freshening tendency of the Antarctic Bottom Water in this basin was estimated. Analysis revealed that the major cause of this freshening is the freshening of the bottom water, flowing into this basin from the east, and its reduction of the flow rate. With this observation network, the baseline structure of stable oxygen isotope was constructed to infer causes of future oceanic change.
我们在南大洋澳大利亚-南极海盆建立了国际海洋观测网络,以稳定氧同位素测量为标准方法,并将结果与以往的水文观测结果进行了比较。估计了该盆地南极底层水的新鲜趋势。分析表明,造成这种淡水的主要原因是从东部流入该盆地的底层水的淡水化和流量的减少。通过这个观测网络,构建了稳定氧同位素的基线结构,以推断未来海洋变化的原因。
