Abstract The most prominent and persistent feature of the eastern Mediterranean Levantine Basin (LB) is the warm anticyclonic Cyprus Eddy (CE) located above the Eratosthenes Seamount (ESM). This eddy periodically couples with two smaller cyclonic and

Abstract Several ocean Western Boundary Currents (WBCs) encounter a lateral gap along their path. Examples are the Kuroshio Current penetrating into the South China Sea through the Luzon Strait and the Gulf of Mexico Loop Current leaping from the Yuc

Experimental observations of internal wave turbulence transition in a stratified fluid
Autor: Costanza Rodda, Clément Savaro, Géraldine Davis, Jason Reneuve, Pierre Augier, Joël Sommeria, Thomas Valran, Samuel Viboud, Nicolas Mordant
Recent developments of the weak turbulence theory applied to internal waves exhibit a power-law solution of the kinetic energy equation close to the oceanic Garrett \& Munk spectrum, confirming weakly nonlinear wave interactions as a likely explanati

The present study has the main purpose to experimentally investigate a turbulent momentum jet issued in a basin affected by rotation and in presence of porous obstructions. The experiments were carried out at the Coriolis Platform at LEGI Grenoble (F

The North Ionian Gyre (NIG) displays prominent inversions on decadal scales. We investigate the role of internal forcing, induced by changes of the horizontal pressure gradient due to the varying density of the Adriatic Deep Water (AdDW), that spread

Can laboratory experiments reach regimes relevant for the oceanic dynamics?
Autor: Pierre Augier, Clément Savaro, Miguel Calpe Linares, Thomas Valran, Samuel Viboud, Antoine Campagne, Joël Sommeria, Nicolas Mordant, Costanza Rodda
Atmospheric and oceanic energy spectra are characterized by global scaling laws, suggesting a common mechanism driving the energy route to dissipation. Although several possible theories have been proposed, it is not clear yet what the phenomena cont

International audience; Oceanic density currents in many deep-water channels are strongly influenced by the Coriolis force. The dynamics of the bottom boundary layer in large geostrophic flows and low Rossby number turbidity currents are very importa
