Geophysical Fluid Dynamics Institute


Welcome to GFDI!

Founded in 1967, the Geophysical Fluid Dynamics Institute fosters collaborative research in fluid dynamics as it applies to the Earth Sciences, Mathematics, and Astrophysics.



Research at GFDI is conducted by our faculty associates using computing, laboratory, and observational facilities at the institute.


PhD's in GFD, Applied Math

GFDI offers an interdisciplinary Ph. D. program in Geophysical Fluid Dynamics, and a joint program in Applied Math and GFD with the FSU Department of Mathematics.

Dr. Hongzhou Xu Colloquium

“Water-mass characteristics, transport and tidal-induced mixing in the southwestern Mariana Trench”


Speaker: Dr. Hongzhou Xu
Institute of Deep-Sea Science and Engineering, Chinese Academy of Sciences

Time: Tuesday, October 11, 2016 at 1:00PM

Place: Melvin Stern Seminar Room, Room 18 Keen Bldg.

Refreshments will be served at 12:45PM


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.
