The INTEGRATION workshop on marine heat waves, co-organised by the SNOs SIROCCO, COAST-HF, MOOSE and SOMLIT as part of the scientific workshops of the ILICO Research Infrastructure and funded by the Office Français de la Biodiversité (OFB), was held in Toulouse from 26 to 28 June 2023. The workshop provided an opportunity to learn about […]
Researchers from LEGOS, NIOZ, LOV, MIO, Espace-Dev, SCCWRP, LOCEAN, and CEFREM investigated the seasonal to annual cycle and budget of dissolved inorganic carbon in the deep convection area of the north-western Mediterranean, using a coupled physical-biogeochemical model. Their results show that the northwestern Mediterranean Sea’s deep-convection region was a moderate sink of 0.5 mol C […]
Two 10-years models hindcast at 150 m and 1km resolution In a partnership with The Pacific Community (SPC), SIROCCO has develloped two level simulation at 1km and 150m resolution to produce Hindcast over 10 years (2010-2019) for the oceanic circulation arround Kiritimati island (Republic of Kiribati). The first stage at 1km is forced at the […]
The last training took place at the Observatoire Midi-Pyrénées, Toulouse, from the 20th to 23rd March 2023. Program
Vietnamese and French researchers from LEGOS, LOG and VAST investigated the daily to interannual variability of the Red River plume in the Gulf of Tonkin using 6-year (2011-2016) high-resolution numerical simulations. Their results show that the temporal evolution of the plume surface coverage is correlated with runoff (with a lag), but that runoff alone cannot […]

The DEWEX (DEnse Water EXperiment) project aimed to better understand this role through an intensive observation platform […]
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 […]
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 […]
