Follow up the establishment of Kinmen Oceanography Prediction System (KOPS), the Institute of Transportation, Ministry of Transportation and Communications (IHMT) have promoted to establish a forecast system named as Matsu Oceanography Prediction System (MOPS) about waves and tidal current conditions, and a field observation system around Matsu water zone to enhance the safety of marine transportations and costal recreation. In this project, the major target is to establish and enhance the MOPS systems. The major works include the setups of wave prediction mdoel and tidal current prediction model, and the statistical analysis of field observation data. Merging into the Harbor Environmental Information Website run by IHMT, the MOPS can offer waves and tidal current and level information to public marine transportation for their safety concern.
