Abstract:

The long-term goal of our project known as OCEAN 3D1 was to better understand and predict ocean circulation features that are fundamentally three-dimensional in space and that vary in time. In particular, we sought to quantify the dynamical processes that govern the formation, evolution, and predictability of 3D1 transport pathways in the ocean. Our approach was to develop algorithms to thoroughly analyze a hierarchy of model and observations, ranging from very idealized models of isolated features waves, eddies, etc. to more realistic features as seen in models or observations.
