My research mostly concerns the study of ocean dynamics using realistic ocean/sea-ice simulations. I am particularly interested in the interactions between mesoscale turbulence (eddies, fronts, overflows) and larger scale ocean structures (gyres, overturning circulation, water masses, inter-basin exchanges), from the size of individual eddies to the global ocean, and on timescales ranging from one day to a few centuries.

I have been mostly working since 1995 on the improvement of realistic ocean simulations (with SPEM, OPA then NEMO ocean models) over several regions of the globe, their detailed comparison with spatial and in-situ observations, and the analysis of their multi-scale variability with the help of Geophysical Fluid Dynamics concepts. I have contributed to the DRAKKAR project since it started (circa 2001), which now gathers a community of about 80 persons at its annual workshops.

I have been working more closely since 2010 on the multi-scale chaotic/intrinsic part of the ocean variability, which emerges spontaneously from hydrodynamic instabilities of large-scale flows, and whose temporal evolution has a strong random character. Its best-known example is mesoscale turbulence, which has relatively small time and space scales (typically weeks to months, and 50-200 km).

A 300-year eddying ocean/sea-ice simulation driven by the same atmospheric forcing every year has demonstrated in a realistic global context that this chaotic/intrinsic character also concerns variability at much larger scales, reaching the size of ocean basins and timescales of 100 years. This large-scale, Low-Frequency Chaotic Intrinsic Variability (LF CIV) can locally explain most of the variance of certain observed climate-relevant indices, questioning their complete dependence on atmospheric variability, or on air-sea coupling.

In the framework of the OCCIPUT research project, we performed in 2015-2016 a pioneering large ensemble (50 members) of long (56 years) global ocean/sea-ice simulations in the turbulent regime. The 50 ensemble members "see" the same atmospheric forcing but were started from slightly different initial states. The 100 Terabytes of OCCIPUT outputs are being analyzed since then in the framework of dedicated research projects (PIRATE, STACCATO, GLO-HR, etc).

These analyses strongly suggest that :
[i] climate-related ocean variability is a complex combination of LF CIV and (atmospherically) forced ocean responses ;
[ii] If one splits the LF ocean variability into CIV and forced variability, the former dominates the latter in several regions of the global ocean ;
[iii] LF CIV strongly impacts ocean climate indices that influence the atmosphere (ocean currents, sea-surface temperature, air-sea heat and CO2 fluxes, inter-basin heat exchanges, ocean heat content at all depth ranges, Atlantic Meridional Overturning Circulation) in key regions, and may thus transfer its chaotic character to the atmosphere ;
[iv] observed ocean time series are just randomly picked out of an ensemble of possible evolutions given a prescribed atmospheric forcing. OCCIPUT is a way to simulate this ensemble of possible evolutions.

In current IPCC-class coupled climate projections, most ocean models are devoid of eddies : in this laminar regime, the ocean generates barely any variability by itself, although it responds to the atmosphere and interacts with it : even without enough ocean non-linearities, ocean-atmosphere coupled interactions generate internal (chaotic) climate variability that is influenced by anthropogenic impacts. But such coupled models lack most of the ocean-generated chaotic variability.

OCCIPUT analyses suggest that a turbulent ocean would generate a strong LF CIV that impacts key regions, and may feed an additional source of internal (chaotic) climate variability

– Animations

Interannual fluctuations of regional sea level (global means are removed). From -10 cm in blue to +10 cm in red.
– The bottom panel (AVISO) shows the real variability as observed from satellite altimeters (TOPEX/Poseidon, Jason-1).
– The middle panel (ORCA025-G70) shows the variability simulated by an eddy-permitting (1/4° resolution) ocean model (NEMO) driven by atmospheric fluxes that are very close to the real world, including in particular its "slow" component (periods up to several decades). This atmospheric forcing directly drives low-frequency ocean variability, which compares well with the bottom panel.
– The top panel (ORCA025-MJM01) shows the variability simulated by the same NEMO model, but driven by the same atmospheric annual cycle every year (i.e. no interannual forcing). The oceanic interannual variability visible in this animation is chaotic and intrinsic, i.e. generated by the ocean itself through non-linear processes.
The OCCIPUT and PIRATE projects aim to disentangle forced and intrinsic ocean variabilities using large ensemble ocean simulations, investigate their dynamics and interactions, and assess their implications for observational oceanography : https://meom-group.github.io/projects/occiput/
