Lagrangian surface signatures reveal upper-ocean vertical displacement conduits near oceanic density fronts

H. M. Aravind, Vicky Verma, Sutanu Sarkar +5

Vertical transport in the ocean plays a critical role in the exchange of freshwater, heat, nutrients, and other biogeochemical tracers. While there are situations where vertical fl…

Seagrass deformation affects fluid instability and tracer exchange in canopy flow

Guilherme S. Vieira, Michael R. Allshouse, Amala Mahadevan

Monami is the synchronous waving of a submerged seagrass bed in response to unidirectional fluid flow. Here we develop a multiphase model for the dynamical instabilities and flow-d…

Uncertainty Quantification of Trajectory Clustering Applied to Ocean Ensemble Forecasts

Guilherme S. Vieira, Irina I. Rypina, Michael R. Allshouse

Partitioning ocean flows into regions dynamically distinct from their surroundings based on material transport can assist search-and-rescue planning by reducing the search domain.…

Using braids to quantify interface growth and coherence in a rotor-oscillator flow

Margaux Filippi, Marko Budisic, Michael R. Allshouse +3

The growth rate of material interfaces is an important proxy for mixing and reaction rates in fluid dynamics, and can also be used to identify regions of coherence. Estimating such…

Internal wave boluses as coherent structures in a continuously stratified fluid

Guilherme S. Vieira, Michael R. Allshouse

Internal waves shoaling on the continental slope can break and form materially coherent vortices called boluses. These boluses are able to trap and transport material up the contin…

Refining and classifying finite-time Lyapunov exponent ridges

Michael R. Allshouse, Thomas Peacock

While more rigorous and sophisticated methods for identifying Lagrangian based coherent structures exist, the finite-time Lyapunov exponent (FTLE) field remains a straightforward a…
