Dans le cadre du meeting annuel du Asia Oceania Geosciences Society (AOGS) à Fukuoka au Japan du 2-7 August 2026, nous attirons votre attention sur les sessions suivantes :
Session OS 08: Ocean Turbulence and Its Influence on Particles, Plankton, and Biogeochemical Dynamics
Session description: The ocean displays pronounced variability across a wide range of spatial and temporal scales—from milliseconds to years, and from millimeters to global dimensions. Turbulence belongs to the major sources of this variability. This session will explore studies of ocean turbulence, encompassing velocity fluctuations, passive and active scalar turbulence, and the transport of particles by turbulent flows. We will place particular emphasis on couplings between turbulence and sediment transport, turbulence and marine chemistry/biogeochemistry, as well as turbulence–plankton interactions, including phytoplankton dynamics (thin layers, blooms, community structure) and zooplankton processes (encounter rates, swimming behavior, abundances, etc.). Contributions drawing on in situ observations, remote sensing, laboratory experiments, and numerical modeling are welcome. Turbulence will be addressed from both Eulerian and Lagrangian perspectives. This interdisciplinary session invites participation from researchers in physical oceanography, marine ecology, fluid dynamics, remote sensing, and mathematical or AI-based modeling.

SE22 - New Caledonia: Geological and Environmental Evolution from Highlands to Deep Ocean Basins
Session description: The archipelago of New Caledonia, located in the southwestern Pacific, has formed through several major tectonic phases. During the Gondwanan phase, New Caledonia formed part of Gondwana's active eastern margin. An extensional phase began in the Late Cretaceous, leading to continental crustal thinning and the development of ridges and basins. In the Eocene, a major tectonic reorganization affected the southwestern Pacific: the region entered a compressive phase marked by the initiation of a subduction zone, which evolved into the Caledonian obduction around 34 million years ago. Since then, regional dynamics have been influenced by the rollback of the Tonga-Kermade subduction slab and the initiation of the Vanuatu subduction zone. The post-obduction phase is dominated by supergene weathering processes, typical of humid tropical environments. This session focuses on studies of New Caledonia across the land-sea continuum, from highlands to deep oceanic basins. Multidisciplinary contributions are strongly encouraged in the fields of geodynamics, tectonics, sedimentology, geochemistry, and geomorphology, following the triptych: observation, experimentation, and modeling. Particular attention will be given to multi-scale approaches-both spatial and temporal-that help advance our understanding of the geological and environmental evolution of New Caledonia.
