PO43D:
Lagrangian Perspectives on Ocean Circulation and Mixing II


Session ID#: 11474

Session Description:
Advances in Lagrangian and semi-Lagrangian instrumentation have made it easier to sample the ocean in two and three dimensions, and at scales down to a meter or less.  Analyses of the trajectories obtained from these instruments is leading to a deeper understanding of dispersion, turbulent and chaotic mixing, and coherent features. At the same time, advances in dynamical systems theory have made it possible to map out coherent Lagrangian structures, such as material boundaries of eddies, in ocean models, and to perform direct assimilation of Lagrangian trajectories into models, all in the presence of complex time dependence.  This session will bring together, and stimulate a lively discussion among, investigators from the various communities (instrument design, field programs, applied mathematics, and data assimilation) that have supported progress in these areas.
