  Information - BG6.06/NP6.09 Coupling biogeochemistry and ecology to fluid dynamics in aquatic ecosystems (co-organized by NP) (co-listed in OS)

Event Information
The structure and functioning of aquatic ecosystems result from the tight interaction between their different physical, chemical and biological components driven by fluid dynamics processes over a wide range of spatial and temporal scales. At the smallest scales, viscosity, molecular diffusion and small-scale turbulence 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, (turbulent) advection transports 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 time and length scales.

Accordingly, we invite contributions from the aquatic biogeosciences researchers linking fluid dynamics to biogeochemistry and/or ecology covering a wide range of questions and scales. For instance, microbial and particle structure as influenced by mechanical energy in the water column; impact of mixing layer dynamics mesoscale eddies on 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, numerical or mathematical models of physical-chemical-biological interactions including the related emerging space-time properties.
