PS31A:
Physical Processes Governing the Distribution and Transport of Dispersed Particles in the Ocean I

Session ID#: 92546

Session Description:
The distribution and transport of dispersed particles in the ocean (e.g., plastic debris, oil droplets, gas bubbles, and organic and inorganic aggregates) continues to gather attention amongst scientists and policymakers seeking local and global solutions. Yet, major gaps remain in our basic understanding of the sources, distribution and physical transport of these different types of particles. Such particles span a wide range of shapes, sizes, densities, and materials and they interact with a wide range of fluid motions, including turbulence, waves, windage, and stratification. This session aims to bring together researchers from different backgrounds seeking to understand the complex physical processes governing the distribution and transport of plastic debris, bubbles, drops, and other particles in the ocean. Thus, we invite all submissions related to physical processes affecting dispersed particles across a range of different scales, from the dynamics of individual particles to global observations and models. Field observations, remote sensing, laboratory experiments, numerical modelling, and theoretical contributions are all welcomed.
