StatusCompleted
Port of departureGreat Yarmouth, United Kingdom
Port of returnGreat Yarmouth, United Kingdom
PurposeResearch
Objectives1. To evaluate the hydrodynamic processes controlling the resuspension of sediment and its seasonal variability at two contrasting sites in the North Sea.
2. To evaluate the influence of sedimentological characteristics and geotechnical and geophysical properties of the bed on the resuspension of sediment at the two sites.
3. To examine the role of benthic and pelagic organisms in sediment resuspension and deposition processes.
4. To determine the impact of sediment resuspension on water quality through its influence on trace metal, nutrient and organic contaminant exchange processes.
5. To develop a detailed model interrelating vertical current structure and suspended sediment concentration at a point site. To use this model as the basis for constructing a fine-grid, 3-dimensional model incorporating sediment transport to cover the observational areas.
