Oceanic fields generally display high variability on a wide range of scales, which is associated with an underlying nonlinear variability and complex coupling between fields and scales.

In this framework, this session will consider scaling and nonlinear aspects of physical, biological, chemical fields in the ocean and freshwaters.

The sessions welcomes theoretical and experimental studies, statistical modelling papers, as well as presentations belonging to nonlinear, scaling, fractal, multifractal, extreme events frameworks.

Specific topics include, for example, scaling, fractal or nonlinear variability studies of:
- Marine turbulence studies;
- Plankton-turbulence couplings;
- Time series analysis: from monitoring networks, long term biological time series, high frequency measurements;
- Spatial variability: heterogeneity and patchiness of aquatic biogeochemical fields;
- Physical-chemical or physical-biological couplings, blooms, marine snow formation;
- Animal behaviour (including plankton) and its coupling with marine environmental variability;
- Biodiversity: rank-abundance scaling properties and species-area relations.
