Quasi-Objective Eddy Visualization from Sparse Drifter Data

  title={Quasi-Objective Eddy Visualization from Sparse Drifter Data},
  author={Alex P. Encinas Bartos and Nikolas O.Aksamit and George Haller},
We employ a recently developed single-trajectory Lagrangian diagnostic tool, the trajectory rotation average (TRA) , to visualize oceanic vortices (or eddies) from sparse drifter data. We apply the TRA to two drifter data sets that cover various oceanographic scales: the Grand Lagrangian Deployment (GLAD) and the Global Drifter Program (GDP). Based on the TRA , we develop a general algorithm that extracts approximate eddy boundaries. We find that the TRA outperforms other available single…

Objective Flow Measures Based on Few Trajectories
This paper introduces the first objective measure of rotation behavior that is based on only few trajectories: at least 3 in 2D, and at least 4 in 3D, called trajectory vorticity (TRV), and shows that it is objective and that it can be introduced in two independent ways: by approaches for unsteadiness minimization and by considering the relative spin tensor.


Improved Surface Velocity and Trajectory Estimates in the Gulf of Mexico from Blended Satellite Altimetry and Drifter Data
AbstractThis study investigates the results of blending altimetry-based surface currents in the Gulf of Mexico with available drifter observations. Here, subsets of trajectories obtained from the
Detecting Lagrangian coherent structures from sparse and noisy trajectory data
This work introduces techniques for identifying Lagrangian Coherent Structures (LCSs) of hyperbolic and elliptic nature in such datasets, and provides a lightweight computational implementation of these techniques as a user-friendly and straightforward Python code.
A daily global mesoscale ocean eddy dataset from satellite altimetry
This dataset, along with the open-source eddy identification software, can be used to extract eddies with any parameters, to study global eddy properties and dynamics, and to empirically estimate the impact eddies have on mass or heat transport.
Erratum:“Quasi-objective coherent structure diagnostics from single trajectories” [Chaos 31, 043131 (2021)]
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 field. Both measures
Oceanic Turbulence and Stochastic Models from Subsurface Lagrangian Data for the Northwest Atlantic Ocean
The historical dataset provided by 700-m acoustically tracked floats is analyzed in different regions of the northwestern Atlantic Ocean. The goal is to characterize the main properties of the
Global characteristics of coherent vortices from surface drifter trajectories
An algorithm is developed that can automatically identify loopers in Lagrangian trajectory data, i.e., looping trajectories that complete at least two orbits, in a significant update to Griffa et al.
Reconstruction of Submesoscale Velocity Field from Surface Drifters
The extensive drifter deployment during the Lagrangian Submesoscale Experiment (LASER) provided observations of the surface velocity field in the northern Gulf of Mexico with high resolution in space
Coherent Lagrangian swirls among submesoscale motions
It is shown that under a suitable extension of the notion of material coherence, coherent eddies at the mesoscale and submesoscale level can indeed be simultaneously detected from multiscale velocity data, and the emergence of coherent Lagrangian swirls (CLSs) among sub Mesoscale motions in the ocean is illustrated.
Gulf Stream eddy characteristics in a high-resolution ocean model
[1] A detailed statistical study of the mesoscale eddy activity in the Gulf Stream (GS) region is performed based on a high-resolution multidecadal regional ocean model hindcast. An eddy detection
Statistical properties of the surface velocity field in the northern Gulf of Mexico sampled by GLAD drifters
The Grand LAgrangian Deployment (GLAD) used multiscale sampling and GPS technology to observe time series of drifter positions with initial drifter separation of O(100 m) to O(10 km), and nominal 5
