The formation mechanisms of turbidity maximum in the Pearl River estuary, China
Marine Pollution Bulletin, 2004The formation and dynamics of turbidity maxima (TM) in the Pearl River estuary (PRE) are not well understood but the existence of TM in the estuary have great potential engineering and environmental impacts. Based on the measurements of two large-scale field surveys conducted in the wet season of 1978 (July of 1978) and the dry season of 1979 (March of

The characteristics of nutrients and eutrophication in the Pearl River estuary, South China
Marine Pollution Bulletin, 2003In the spring of 1998, 24-h time series and synchronization of vertical profiles of NO(3)-N, NO(2)-N, NH(3)-N, PO(4)-P, chlorophyll a, suspended substance, salinity, temperature and other chemical parameters were taken at 10 stations in the Pearl River estuary in order to analyze the status and characteristics of nutrients and eutrophication.

Modelling of the wave-current interaction in the Pearl River Estuary
Journal of Hydrodynamics, Ser. B, 2006A wave propagation model based on the wave action conservation theory was developed and applied to the modelling of wave characteristics and the interaction of wave and current in the Pearl River Estuary, by coupling with a three-dimensional hydrodynamics model.

Spatial and temporal variation of picophytoplankton in the Pearl River Estuary
Acta Ecologica Sinica, 2013Picophytoplankton are distributed worldwide and are ubiquitous in all types of waters of varying trophic state.They are the major players in carbon production and form the base of complex microbial food webs.It is generally known that picophytoplankton have a competitive advantage when nutrients are limited.In recent years,picophytoplankton(0.2—2) have

Trace Metals and Ecotoxicological Effects in the Pearl River Estuary
2020Biomarkers are used to assess the biological impacts of contaminants on aquatic organisms. There are various levels of biological organization at which biomarkers can be employed, but identifying specific and sensitive biomarkers in a multicontaminated estuarine environment is challenging.

Riverine fluxes of different species of phosphorus in the Pearl River estuary
Marine Pollution BulletinPhosphorus is the most limiting nutrient in coastal waters of China, particularly in the Pearl River (PR) estuary. Rivers have different P forms including dissolved inorganic phosphorus (DIP), dissolved organic phosphorus (DOP), particulate inorganic phosphorus (PIP), and particulate organic phosphorus (POP).

Characteristics of vertical exchange process in the Pearl River estuary
Aquatic Ecosystem Health & Management, 2016Being an estuary with the occasional appearance of hypoxia, the Pearl River estuary was selected to investigate its vertical exchange process by a validated 3-D numerical model. The concept of vertical exchange time was used to quantify the vertical exchange process and was calculated by adding a conservative tracer to the hydrodynamic model.

Spatial distribution of the summer chlorophyll a and nutrients in the Pearl River Estuary
Marine Pollution BulletinEstuaries, critical land-sea interfaces, mediate terrestrial inputs and sustain coastal ecosystems, with high ecological and economic significance. The Pearl River Estuary (PRE), the largest estuary in southern China and a core of the high-density Guangdong-Hong Kong-Macau Greater Bay Area, connects the Pearl River to the South China Sea, experiencing ...

Tidal energy budget in the Zhujiang (Pearl River) Estuary
Acta Oceanologica Sinica, 2016Tidal energy budget in the Zhujiang (Pearl River) Estuary (ZE) is evaluated by employing high-resolution baroclinic regional ocean modeling system (ROMS). The results obtained via applying the least square method on the model elevations are compared against the tidal harmonic constants at 18 tide stations along the ZE and its adjacent coast.

Patterns of potential sediment erosion in the Pearl River Estuary
Journal of Marine Systems, 2010The interrelations between tidal currents and grain size of sediment of the Pearl River Estuary (PRE), South China Sea, have been investigated. The current system has been described by numerical model data for wet and dry seasons. Measured data from samples have been used for the parameterisation of the fades of the uppermost sediments. These data were
