摘要： 东印度洋深海是全球深海系统的重要组成部分，在全球碳循环、热量分配和营养物质运输中具有重要作用。东印度洋深海被90oE海岭分成中印度海盆和西澳大利亚海盆，两个海盆间的水团特性和环流具有显著差异。为了进一步深入理解东印度洋的深海环流及水团特征，本文通过回顾现有的研究成果，本文总结和阐述了：1)东印度洋深海地形的特殊性；2)深海水团的来源和路径；3)深层经向翻转环流；4)中印度海盆和西澳大利亚海盆之间的深层水团的差异和联系。最后，本文提出了未来东印度洋深海研究中需要重点关注的科学问题，为开展相关研究提供参考。

Abstract: The deep sea of the Eastern Indian Ocean is a crucial component of the global deep-sea system, playing a significant role in the global carbon cycle, as well as the distribution of heat and nutrients. The Eastern Indian Ocean deep sea is divided by the Ninety East Ridge into the Central Indian Basin (CIB) and the West Australian Basin (WAB), with notable differences in water mass characteristics and circulation between the two basins. To further understand the deep-sea circulation and water mass features in the Eastern Indian Ocean, this paper reviews existing research findings and summarizes the following aspects: 1) the unique topography of the deep Eastern Indian Ocean; 2) the sources and pathways of deep-sea water masses; 3) the deep meridional overturning circulation; 4) the differences and connections between the deep-sea water masses in the CIB and the WAB. Finally, this paper highlights key scientific issues that need to be addressed in future researches on the Eastern Indian Ocean deep sea, providing a reference for related studies.
