Small-scale Physics and Turbulence
There are a vast range of scales of motion that are present in the ocean -- from the large-scale oceanic gyres that fill the ocean basins, to the millimetre sized eddies in a turbulent tidal pool. It is this range of scales that presents the greatest difficulties in both observing and modelling ocean dynamics.
These difficulties are a major scientific obstacle facing society today, since in recent years intensive resources are being devoted to understanding the processes shaping our weather and climate.
The newly formed "Small-scale Physics and Turbulence" group works to understand ocean circulation, mixing, and processes that transport important quantities such as heat, salt, oxygen and nutrients, through a study of the smallest turbulent scales of motion.
Utilizing robotic ocean gliders for direct field measurement, high performance computer clusters for conducting numerical simulations, as well as construct theoretical models -- all to help understand and model turbulent processes in the oceans. Current, and ongoing, fields of investigation include:
- North Sea coastal turbulence
- Ocean impacts of offshore wind farms
- Turbulent transport of heat in the Arctic Ocean
