  Information - BG6.03/NP6.04 Coupling biogeochemistry and ecology to fluid dynamics in aquatic ecosystems (co-organized by NP) (co-listed in SSS)

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 small 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, effect of small-scale turbulence on gas and nutrient diffusion at the cellular boundary layers, mathematical models of physical-chemical-biological interactions, or examples of the biological control on fluid dynamics (e. g. ecosystem engineering).
