CANCELLED DUE TO COVID-19 RISK.Suspensions of solid particles and liquid drops are ubiquitous in natural turbulent flows: riverine discharges into the open ocean, marine snow (plankton and other carbonaceous matter) in the ocean, cloud droplets, spreading of volcanic ash and dust storms. In each of them there are physical questions of importance. This meeting will bring oceanographers, cloud scientists and fluid mechanicians studying particle and droplet transport together and those making observations in contact with modellers and theorists.Plankton and other small living beings are found in relatively high concentration in the upper few metres of the ocean. The debris generated sinks to the deeper ocean, and has a major role in carbon sequestration. As they sink, hydrodynamic interactions and cohesive attractions between particles create larger particles of arbitrary shape. Droplets and ice crystals in a cloud need to come in contact and coalesce to grow into raindrops, and turbulence...
