Lagrangian analysis of submesoscale flows from sparse data using Gaussian Process Regression for field reconstruction
Lagrangian analyses of oceanic flows provide insight into the various transport pathways in
the ocean. This analysis typically relies on a dense set of trajectories that can be computed …

Stochastic sensitivity: A computable Lagrangian uncertainty measure for unsteady flows
S Balasuriya - SIAM Review, 2020 - SIAM
Uncertainties in velocity data are often ignored when computing Lagrangian particle
trajectories of fluids. Modeling these as noise in the velocity field leads to a random …

Drifter Deployment Strategies to Determine Lagrangian Surface Convergence in Submesoscale Flows
Surface convergence in the ocean is associated with accumulation of buoyant pollutants as
well as with vertical transport that is important to biological activity. Such surface …

Assessing the information content of complex flows
L Fang, NT Ouellette - Physical Review E, 2021 - APS
Complex dynamical systems can potentially contain a vast amount of information. Accurately
assessing how much of this information must be captured to retain the essential physics is a …
