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.…

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…
