Constraining The Connection Between The SW Indian Ocean Monsoon And North Atlantic Climate

科学总结：该提案要求支持测试假设，即阿拉伯海氧气最低区强度的千年变化与西南印度洋季风相关的上升有利风强度的变化直接相关。 季风驱动的生产力的过去的变化将跟踪测量代理（231 Pa/230 Th比），是不敏感的沉积物集中和底层水含氧量的变化。 这项研究将对巴基斯坦边缘的沉积物岩心进行。

Science Summary: This proposal requests support to test the hypothesis that the millennial changes in Oxygen Mimimum Zone intensity in the Arabian Sea are directly related to changes in the intensity of upwelling-favorable winds associated with the SW Indian Ocean monsoon. Past changes in monsoon-driven productivity will be traced by measuring a proxy (231Pa/230Th ratio) that is insensitive to sediment focusing and to changes in bottom water oxygen content. The study will be performed on sediment cores from the Pakistan margin.
