The study is aimed at understanding the changes in chemistry and circulation of the SE Indian Ocean during the glacial late Quaternary. The specific questions that the study will focus on concern the vertical distribution of dissolved nutrients and oxygen deficit in the deep and intermediate waters during the last glacial, and upwelling off NW Australia as predicted by climate reconstructions of that time. Cores are planned to be collected from the NW Australian margin by the Australian Bureau of Mineral Resources ship Rig Seismic. These will be analyzed for the calcium carbonate and organic carbon content, as well as stable isotopes to answer the proposed questions.

这项研究旨在了解化学的变化 晚冰期东南印度洋的环流 第四纪。 研究将重点关注的具体问题 关注溶解营养物的垂直分布， 深水和中层沃茨缺氧 最后一次冰期，澳大利亚西北部的上升流， 当时的气候重建。 核心计划是 澳大利亚人从澳大利亚西北部的边缘收集到的 矿产资源局船舶钻机地震。 这些将是 分析碳酸钙和有机碳含量， 以及稳定同位素来回答这些问题。
