Welcome to Guangzhen's Homepage.

The ocean is a crucial element in the Earth’s climate and biological system and is also a key regulator of life on our planet as ocean phytoplankton generate half of the oxygen we breath.

I am interested in understanding how the ocean achieves these global effects which requires understanding the dynamic process that drives large scale current on scales from thousands of kilometers down to mixing on scale of millimeters and have been throwing myself into finding possible methods including in-situ and remote sensing data, theoretical analysis, numerical simulation and data assimilation to solve the puzzle.

Internal waves, or more accurately internal gravity waves, are one of the major players in ocean dynamics which are ubiquitous in the ocean. Because of their strong vertical and horizontal currents, and the turbulent mixing caused by their breaking, they affect a panoply of ocean processes, such as the supply of nutrients for photosynthesis, sediment and pollutant transport, acoustic transmission; and hazard posing for man-made structures in the ocean.

My researches were centered around the dynamic and energetic characteristics of internal waves, in particular internal tides, nonlinear internal waves and near-initial waves. In the past few years, I have worked or been working on the following topics including investigations of the generation and propagation processes of internal waves with different approaches mentioned above.

1. Observational Analysis of Internal Waves in the South China Sea;

2. Large-scale Numerical Simulations of Internal Wave based on High Performance Computation;

3. 4D-Var Data Assimilations and Simulations for Internal Tides.

My recent ongoing work also focuses on transdisciplinary research which includes: 1) data-driven image transformation, 2) remote sensing data mining and 3) analysis and microplastic spreading from coastal area in a Lagrangian view.
