Direct observational evidence of an oceanic dual kinetic energy cascade and its seasonality

D Balwada, JH Xie, R Marino, F Feraco - Science Advances, 2022 - science.org
The ocean's turbulent energy cycle has a paradox; large-scale eddies under the control of
Earth's rotation transfer kinetic energy (KE) to larger scales via an inverse cascade, while a …

Vertical fluxes conditioned on vorticity and strain reveal submesoscale ventilation

D Balwada, Q Xiao, S Smith… - Journal of Physical …, 2021 - journals.ametsoc.org
It has been hypothesized that submesoscale flows play an important role in the vertical
transport of climatically important tracers, due to their strong associated vertical velocities …

TTM Hong, YG Park, JM Choi - Remote Sensing, 2023 - mdpi.com
Oceanic mesoscale eddies continuously regulate the horizontal and vertical transport of
mass, heat, salt, carbon, and nutrients throughout the ocean system owing to their ubiquity …

Particle dispersion and clustering in surface ocean turbulence with ageostrophic dynamics

M Maalouly, G Lapeyre, B Cozian, G Mompean… - Physics of …, 2023 - pubs.aip.org
Upper-ocean turbulent flows at horizontal length scales smaller than the deformation radius
depart from geostrophic equilibrium and develop important vertical velocities, which are key …

Drifter observations reveal intense vertical velocity in a surface ocean front

DR Tarry, S Ruiz, TMS Johnston… - Geophysical …, 2022 - Wiley Online Library
Measuring vertical motions represent a challenge as they are typically 3–4 orders of
magnitude smaller than the horizontal velocities. Here, we show that surface vertical …

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

HM Aravind, V Verma, S Sarkar, MA Freilich… - Ocean Modelling, 2023 - Elsevier
Vertical transport in the ocean plays a critical role in the exchange of freshwater, heat,
