Lagrangian analysis is a powerful way to analyse the output of ocean circulation models and
other ocean velocity data such as from altimetry. In the Lagrangian approach, large sets of …

Typical fluid particle trajectories are sensitive to changes in their initial conditions. This
makes the assessment of flow models and observations from individual tracer samples …

A vortex is intuitively recognized as the rotational/swirling motion of the fluids. However, an
unambiguous and universally accepted definition for vortex is yet to be achieved in the field …

Rotationally coherent Lagrangian vortices are formed by tubes of deforming fluid elements
that complete equal bulk material rotation relative to the mean rotation of the deforming fluid …

We review and test twelve different approaches to the detection of finite-time coherent
material structures in two-dimensional, temporally aperiodic flows. We consider both …

Amongst the variety of oceanic processes running the gamut of spatiotemporal scales,
mesoscale eddies are the most common and often have region-specific characteristics. The …

Mesoscale ocean eddies are ubiquitous coherent rotating structures of water with radial
scales on the order of 100 kilometers. Eddies play a key role in the transport and mixing of …

There are fundamental gaps in our understanding of the fates of microplastics in the ocean,
which must be overcome if the severity of this pollution is to be fully assessed. The …

Mesoscale eddies are ubiquitous features in the Southern Ocean, yet their phenomenology
is not well quantified. To tackle this task, we use satellite observations of sea level …

One of the ubiquitous features of real-life turbulent flows is the existence and persistence of
coherent vortices. Here we show that such coherent vortices can be extracted as clusters of …
