The Eulerian and Lagrangian Predictability of Oceanic Flows

Abstract

The long-term goal is to improve our capabilities and scientific knowledge concerning Lagrangian predictability in the ocean. Specific applications include search and rescue operations, the design of float and drifter experiments, and the understanding of stirring mechanisms. The objectives are: 1) To identify robust geometrical structures that help distinguish regions of inherent unpredictability (Lagrangian chaos) from predictable (regular) regions. 2) Also, to identify geographical regions in the ocean where such a separation is appropriate, i.e., where Lagrangian motion is controlled by chaotic advection and not by small-scale turbulence.
