Dear all,
If you plan to attend the 2026 Ocean Sciences Meeting in Glasgow, please consider submitting your work to the following session. The abstract submission deadline is August 20, 2026.
PS014 - Transport and dispersal of passive and non-passive tracers and particles.
The transport of water masses, solutes (e.g., heat, salt, nutrients, carbon, and pollutants), and dispersed particles (e.g., microplastics, marine organisms, aerosols, sediment, organic and inorganic aggregates, bubbles, and droplets) plays a central role in the oceans and related aquatic environments (e.g., rivers, lakes, and the air-water interface). These transport processes are governed by complex Lagrangian dynamics and complex interactions between fluid motions (e.g., turbulence, waves, stratification) and particle properties (e.g., size, shape, density, motility). To model the implications of the dispersal and transport of water masses, solutes, and particles requires a fundamental understanding of particle-flow interactions. Additionally, Lagrangian analyses of the trajectories of water masses, tracers and particles can sometimes be more beneficial than the more conventional Eulerian transport analysis. Thus, new understanding can come from focused investigations that isolate individual processes, be it in field observations, remote sensing, laboratory experiments, or numerical modelling. And new understanding can also come from Lagrangian analysis real-world data from drifters, gliders, Argo floats or biologging, where the Lagrangian analysis techniques come in different forms and flavors. These can span from theoretical dynamical systems developments to statistical, stochastic, or probabilistic analysis to complex coupled-system numerical modeling describing, for example, biophysical interactions, evolution of chemically active tracers, non-water-following tracers, or dynamically active tracers that feedback on the flow. In this session, we invite participants from all aspects of the science of particle and tracer transport. We welcome contributions from theoretical, numerical, or observational research across disciplines and application areas and spanning a wide range of scales, from the individual particle to large-scale global observations.
Chairs: Jezabel Curbelo, Nimish Pujara, Irina Rypina, Ton van den Bremer, Theresa B Oehmke
Best wishes,
Nimish Pujara
