Recent publication : Oxygen budget of the north-western Mediterranean deep- convection region.

Caroline Ulses, Claude Estournel, Marine Fourrier, Laurent Coppola, Faycal Kessouri, Dominique Lefevre, Patrick Marsaleix; 2021 Biogeosciences 18(3):937-960 DOI:10.5194/bg-18-937-2021 The north-western Mediterranean deep convection plays a crucial role in the general circulation and biogeochemical cycles of the Mediterranean Sea. The DEWEX (DEnse Water EXperiment) project aimed to better understand this role through an intensive observation platform […]

Dynamics of the North Balearic Front

Dynamics of the North Balearic Front during an autumn tramontane and mistral storm: air–sea coupling processes and stratification budget diagnostic  The North Balearic Front forms the southern branch of the cyclonic gyre in the northwestern Mediterranean Sea. Its dynamics exhibit significant seasonal variability. During autumn, the front spreads northward during the calm wind periods and […]

3D phase-resolved wave modelling with a non-hydrostatic ocean circulation model

SIROCCO developers derived a phase-resolved wave model from an ocean circulation model SYMPHONIE for the purpose of studying wave-current effects in nearshore zones. One challenge is to adapt the circulation model to the specificities of wave physics. This mainly concerns the consideration of non-hydrostatic effects and the parametrization of wave breaking. The non-hydrostatic pressure is […]

Modeling the impact of thin scales on the circulation in the Mediterranean

The group SIROCCO LA was one of the winners of the “mesochallenge” launched by the mesocentre CALMIP to test the new supercomputer OLYMPE (1,365 Petaflop / s, 13464 cores of calculations, 76 TB of memory). The challenge was to use a significant portion (up to 12960 calculation cores) of the OLYMPE computing system to deal […]

2017 : 3D ocean modelling training at Cotonou, December.

A SYMPHONIE ocean model training was held from December 11 to 23, 2017, at the Institut des Recherches Halieutiques et Océanographique du Bénin(IRHOB), in Cotonou (Benin). The training was organized by IRD and LA. It involved researchers from France and Benin. The objective was to build skills in ocean modelling: installation of the code, compilation, […]
