Abstract
This paper develops a satellite-based monitoring system for observations of spatial and temporal variations of turbidity of the sea surface around Hai Phong Bay in the northern part of Vietnam. The monitoring system is based on MODIS and consists of sub-tools required for the monitoring, such as cloud masking and turbidity estimations based on multiple band data. The developed system is validated through comparisons of estimated and measured turbidity patterns around Hai Phong Bay. The system is then applied for monitoring of turbidity patterns around the bay over the past sixteen years and it was found through the monitoring that observed turbidity shows decreasing trend after the construction of dams along the upstream of the rivers around the area.
