At the smallest scales, water turbulence and viscosity may have direct and indirect effects on the physiology, activity and trophic links of aquatic organisms ranging from bacteria to macrophytes; at the scale of a few to tens of meters, advective and turbulent flows transport planktonic organisms and chemicals around the water column; mesoscale structures such as eddies and fronts affect the dynamics of the ecosystem from the low (primary producers) to high (fish) trophic levels; finally, at the long geological scale, global oceanic and atmospheric circulation interact with the biological pump modulating the biogeochemical fluxes of essential elements. With a clear interdisciplinary perspective, this session will focus on hydrodynamics as a major determinant on biogeochemical and ecological processes in different aquatic ecosystems and at different scales. Accordingly, we invite contributions covering a wide range of questions and scales, for instance, microbial and particle structure as influenced by mechanical energy in the water column; interaction between mixing layer dynamics and biological productivity or plankton patchiness; effect of small-scale turbulence on gas and nutrient diffusion at the cellular boundary layers and on behavioural processes (e.g. related to prey/mate encounter and predator avoidance); or examples of the biological control on fluid dynamics (e. g. ecosystem engineering). Different approaches are welcome, experimental, theoretical or mathematical models of physical-chemical-biological interactions including the related emerging space-time properties.
