Transports in fluids can be approached from two complementary perspectives. In the Eulerian view of mixing, the focus is on the concentration field. In the Langrangian view, fluid parcels are followed around as they move with the flow, experiencing chaotic or stochastic motion. This book examines both pictures, presenting a number of theoretical and experimental lectures on various aspects of transport and mixing of active and passive particles in geophysical flows.
