NICOP - GULF OF TONKIN OCEAN CIRCULATION STUDY

Abstract

The U.S. – Vietnamese collaboration will be accomplished through a series of research activities in a collaborative manner for purposes of studying the oceanographic and atmospheric forces and responses in the Gulf of Tonkin. These research activities will include: • Installation of meteorological stations, boat based CTD and drifter observations, as well as autonomous glider observations combined with the QA/QC of HF radar monitoring stations data. Collected data (HF radar and otherwise) will be used to establish climatology, calibrate and verify the hydrodynamic numerical models; the collected data will also be used to assess the quality of the HF radar data, and to assist in the calibration of the HF radar systems. HF radar data will be one of the primary data sources for verification the accuracy of the numerical models for the western portion of Gulf of Tonkin; • Collect and synthesize historical data (HF Radar, Meteo–hydrological observation stations along Vietnam coastline and islands, NAGA surveys, Soviet-VN cooperation surveys, NODC, and other cooperative programs) to use in conjunction with observational data for studying and analyzing the seasonal exchange of oceanographic dynamic processes in the western portion of the Tonkin Gulf and the Bien Dong sea; • The collection, processing, and global re-analysis of meteorological data serve as meteorological input for oceanographic numerical models in the analysis of currents and waves within the Bien Dong sea and the west coast Gulf of Tonkin; • Collection and processing of bathymetric data will be used in the construction of computational grids for oceanographic numerical models; • Tasks related to the research and application of climate-oceanographic models (WRF, SWAN and ROMS) utilized for predicting waves and currents. Surface current data from HF radar will be used to assess the ROMS model; by the; • Training of CFO researchers in the use of the ROMS model, including training on calibration and processing of the HF radar for assimilation by the ROMS model. The implementation of an ocean waves and currents monitoring system (three monitoring sites, one central station) utilizing HF radar completes the first project phase. The collected data was initially studied for a number of different purposes. However, this still is an entirely new field for Vietnam. Therefore, the evaluation and adjustment of radar parameters need to be made through the scientific experts in this field (e.g., Scripps Institution of Oceanography researchers). The evaluation and adjustment of HF radar monitoring data is essential for quality synthesized data needed for assimilation in numerical models in Tonkin gulf, as well as coastal regions of Vietnam. Due to the request and the basis of existing data sources, the project proposes “Investigate, research and apply hydro-dynamic numerical model for re-analysis and prediction of ocean waves and currents in Bien Dong sea and the west region of Tonkin gulf” with the funding of U.S. Office of Naval Research (ONR) and scientific research collaboration with Scripps Institution of Oceanography, Oregon State University and Rutgers in the 2015 – 2017 period.
