Late Quaternary Paleochemistry of the Southeast Indian Ocean

本研究旨在了解晚第四纪冰期印度洋东南部的化学和环流变化。该研究将重点关注的具体问题是，末次冰期深层和中层水体中溶解营养物质的垂直分布和缺氧，以及当时气候重建预测的澳大利亚西北部上升流。计划由澳大利亚矿产资源局的Rig Seismic船从澳大利亚西北部边缘收集岩心。这些将被分析碳酸钙和有机碳含量，以及稳定同位素来回答提出的问题。

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.
