Detection of Lagrangian Coherent Structures in oceanic flows

The Atlantic Meridional Overturning Circulation (AMOC) is a complex system of shallow and deep currents in the Atlantic Ocean which plays a crucial role in the regulation of the Earth's climate. Lagrangian Coherent Structures (LCS) are geometric objects existing in the extended phase space of d...
