China Sea Multi-Scale Ocean Modeling System (CMOMS)

The Ocean Dynamics and Modeling Program (ODMP) aims to develop multi-scale coupled physical-biogeochemical models on China Sea (CS), East China Sea (ECS), South China Sea (SCS), Northern South China Sea (NSCS) and Pearl River Estuary (PRE); to establish an integrated database that includes the historic data, field measurement, model output and the results from other research programs; to conduct kinematic and dynamic vestigations of the physical, and associated bio-geochemical processes in carbon cycle based on synthesized model and observed data and to intensify our understanding of the role of ocean in climate change, environmental pollution, and sustainable development. The ODMP will emphasis on the environment and ecosystem, providing scientific support and assistance for the marine environmental management and administration of coastal regions.

Research strategy

Numerical simulation:

The model development and modeling study are important component in investigating ocean circulation and its associated biogeochemical responses. They will be utilized to interpolate and/or extrapolate the spatially and temporally limited field measurements in understanding the processes and dynamics that govern the ocean circulation and biogeochemical cycle in the China Sea. The model and modeling study are also the necessary and effective tools for diagnostic and prognostic studies of physical-biogeochemical processes in the China Sea. The main objective of this study is to develop a coupled physical-biogeochemical model that is physically/biologically suitable for continental shelves and marginal seas in China Sea.With ocean models, we can:

    • Develop and enhance understanding;
    • Quantify descriptions of processes;
    • Synthesize and consolidate our knowledge;
    • Establish interaction of theory and observation;
    • Develop predictive potential;Simulate scenarios of past and future developments.

Field observation:

The combined observational and modeling study is scientifically important and necessary to understanding the extremely complicated nature of the time-dependent three-dimensional variability of oceanic circulation and the associated biological and chemical responses. Based on Guangzhou HKUST Fok Ying Tung Graduate School, field observation in the adjacent Pearl River Estuary and the continental shelf of the Northern South China Sea is another main task of ODMP. Parameters will be measured including salinity, temperature, current velocity, nutrients concentration etc.

The instruments including:

    • SBE 25 SEALOGGER CTD (SBE 55 ECO Water Sampler);
    • WHS-300, 600 Workhorse SENTINEL self-contained ADCP standard system;
    • T-S Chain;
    • Nutrient analyzer;
    • Fluorometer.
