Identifications of water-mass characteristic and vertical mixing intensity can help oceanographers to better understand ocean circulation structures and transport processes in open oceans. They were recognized well by extensive observations and simulations in the upper ocean. Nevertheless, rare related studies were conducted in deep oceans, especially for deep trench range from 6,000 m to 10,000 m in depth. In this talk, two topics in the world deepest trench will be presented and discussed.
1) Water-mass distributions and transport in the southwestern Mariana Trench of the northwestern Pacific Ocean by CTD dataset. The preliminary results show complex vertical structures of water mass in this trench. And the transport of AABW can reach about 2.5 SV which is much larger than previous studies.
2) Simulations of internal tide and it-induced turbulent mixing in the trench by MITgcm numerical model. It can be found strong vertical mixing are motivated by interaction between internal tide and trench topography.
