Lunch Talk Series by Earth, Ocean and Atmospheric Sciences (EOAS) Thrust, HKUST (GZ) - Dynamic mechanism of cross-shelf water exchange in the northern South China Sea
The flow on the northern shelf of the South China Sea is an important component of the coastal flow in China. It connects the vast northern South China Sea and the southern East China Sea shelf waters from the eastern slope of Hainan Island to the Taiwan Strait. Cross-shelf water exchange is an important carrier for the renewal of water bodies in the coastal waters of southern China, greatly determining the marine environmental health of the Guangdong-Hong Kong-Macao Greater Bay Area. Based on years of numerical model and field observation results, this report systematically analyzes the dynamic mechanism regulating cross-shelf water exchange in the northern South China Sea from the perspectives of circulation dynamics and eddy dynamics. It proposes that the response of shelf flow to meandering topography is an important dynamic factor regulating water exchange across the shelf.
Liu Zhiqiang is an Assistant Professor in the Department of Ocean Science and Engineering at the Southern University of Science and Technology. His research focuses on multi-scale ocean dynamics and biogeochemical processes in the waters near the Guangdong-Hong Kong-Macao Greater Bay Area. He has conducted systematic studies on the characteristics, variations, and modulation mechanisms of Chinese sea shelf and slope currents, as well as material transport phenomena. From 2013 to 2024, his research has centered on the dynamic processes of ocean circulation in the Chinese seas, investigating cross-shelf/slope transport dynamics mechanisms, and conducting multi-scale ocean circulation numerical simulations. During this period, he has authored 45 research papers in leading SCI journals in ocean dynamics, including the Journal of Geophysical Research, Journal of Physical Oceanography, Ocean Modelling, and Progress in Oceanography. Of these publications, 24 are credited to him as the first or corresponding author. His research contributions have earned recognition from scientists both domestically and internationally. Since 2015, Liu Zhiqiang has led multidisciplinary comprehensive field investigation voyages in the northern South China Sea basin-slope-shelf. Through these studies, he has conducted in-depth studies on marine environmental processes in the waters of the Guangdong-Hong Kong-Macao Greater Bay Area.
As this is a lunch seminar, refreshments will be provided. All are welcome.
