ABSTRACT:
This study utilizes tools developed in dynamical systems theory to examine how fluid
flows in the gulfstream off the coast of Florida. Using theoretical and numerical descriptions of
local finite time Lyapunov exponents (FTLEs), it is possible to identify "Lagrangian Coherent
Structures" in time-dependent flow fields. These structures are bounded by persistent lines of
trajectory shredding and folding that are barriers to mixing between adjacent parcels of fluid.
This study reviews established Eulerian and Lagrangian techniques for identifying dynamically
distinct regions of the flow and explores the functioning and limitations of applying the FTLE
methodology to the special case of high-resolution model data in the Florida Straits region.
