Quasi-Objective Eddy Visualization from Sparse Drifter Data
Alex P. Encinas Bartos, Nikolas O. Aksamit, George Haller
We employ a recently developed single-trajectory Lagrangian diagnostic tool, the trajectory rotation average , to visualize oceanic vortices (or eddies…

Objective Momentum Barriers in Wall Turbulence
Nikolas O. Aksamit, George Haller
We use the recent frame-indifferent theory of diffusive momentum transport to identify internal barriers in wall-bounded turbulence. Formed by the invariant manifolds of the Laplac…

Quasi-Objective Coherent Structure Diagnostics from Single Trajectories
George Haller, Nikolas Aksamit, Alex P. Encinas Bartos
We derive measures of local material stretching and rotation that are computable from individual trajectories without reliance on other trajectories or on an underlying velocity fi…
