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90°E海岭分成中印度洋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, 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)中印度洋海盆和西澳大利亚海盆之间深层水的差异和联系。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, 旨在为该领域的进一步研究提供参考。

Abstract:

The deep water of the Eastern Indian Ocean is a crucial component of the global deep-sea system, playing a significant role in the global carbon cycle and the distribution of heat and nutrients. It is divided by the Ninety East Ridge into the Central Indian Basin (CIB) and the West Australian Basin (WAB). These two basins exhibit distinct differences in their water mass characteristics and circulation patterns. 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; and 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 research on the deep sea of the Eastern Indian Ocean, providing a reference for related studies.

Key words: Eastern Indian Ocean, deep sea, circulation, water masses
