Late Quaternary Paleochemistry of the Southeast Indian Ocean

这项研究旨在了解冰期晚第四纪期间东南印度洋的化学和环流变化。这项研究将关注的具体问题涉及最后一次冰期期间深水和中水中溶解营养物质和氧气的垂直分布，以及当时气候重建所预测的澳大利亚西北部附近的上升流。澳大利亚矿产资源局计划从澳大利亚西北部边缘采集岩心，钻探平台地震。这些将分析碳酸钙和有机碳的含量，以及稳定同位素，以回答拟议的问题。

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.
