2.9 Summary and conclusions
High (orbital) velocities under waves cause resuspension of sediments, that may lead to substrate change, reduced light in the water, and movement of nutrients and other chemicals.
Our sediment modelling suggests that, for the SW shelf region during the winter, sand-sized sediments are mobile for between 50 and 60% of the time.
The implications of the physical oceanography are pursued in following chapters. In particular, in Chapter 4, hydrodynamic and sediment models are combined with biogeochemical models to describe the shelf-scale biogeochemistry. Then, Chapter 6 explores the interaction between waves and benthic habitat. These are preliminary investigations. With improved understanding of the physical environment across the shelf, we are now much better placed to explore cross- disciplinary links, through better design of interdisciplinary experiments, and the continued implementation of coupled models.
