Contributions are invited on innovative observational, theoretical and modelling studies concerning physical processes in coastal and shelf seas. Processes can include hydrodynamics (e.g., waves, tides, currents and Stokes drift, upwelling, eddies, density structures), transport of material (e.g., sediments, contaminants, litter, nutrients), and morphodynamics (e.g., evolution of bed forms, banks or basin shape). Study areas are envisaged between the base of the shelf break and the seaward limit of the surf zone. However, contributions on processes outside these geographical limits will be considered where they significantly influence processes within these limits. Equally, contributions on climate dynamics, biogeochemistry, and man-made structures will be considered where they significantly influence, or are significantly influenced by, the processes aimed at in this session. In addition to the above, this session welcomes coastal and shelf seas related abstracts that do not fit into the more specialist sessions. Special attention will be given to interactions between physics and biology/biogeochemistry . . Two subsessions are envisaged: (i) on the Baltic Sea, with emphasis on the Baltic Earth programme, focusing on sea-level variability, salinity dynamics and water budget, biogeochemical feedbacks, extreme events and anthropogenically induced changes; and (ii) on the environmental impacts of marine renewable energy generation from wind, waves and tides, including oceanographical and biological interactions with the resource, biological interactions with the devices and managing space, and considering modelling and quantification, ecological study designs and methods, new technologies for quantification, and habitat and community change.
