Scope Recent progress in ocean observation and numerical modelling shed light on tight linkage between small scale ocean mixing, a fundamental physical process that mixes sea water and dissolved and suspended substances due to turbulent eddies, and large scale chemical, biogeochemical and biological processes as well as physical processes. For example, mixing in ocean surface layer (whose typical scales are less than 100m) and consequent entrainment process of subsurface water have basin scale (~1000km) impacts on biogeochemical cycles and resulting primary production (and potentially CO2 uptake by photosynthesis). In deeper layers, diapycnal mixing due to breaking internal wave generated by tidal currents over rough topography connects to basin and global scale ocean vertical circulations of water, heat and materials. In this session, in order to understand these mixing-related physical, chemical and biological processes from small to large scales, and to understand long term ocean and climate variability, new interdisciplinary presentations and active discussions are welcomed from physical, chemical and biological oceanography and its related fields.
