Combined physical and biogeochemical assessment of mesoscale eddy parameterisations in ocean models: Eddy induced advection at non-eddying resolutions
Ruan, X.; Couespel, Damien; Lévy, M.; Li, J.; Mak, J.; Wang, Y. (Peer reviewed; Journal article, 2023)Ocean components of Earth System Models employed for climate projections do not routinely resolve mesoscale eddies for computational cost reasons, and the associated subgrid processes are still parameterised. While the ... -
The Impact of Fine-Scale Currents on Biogeochemical Cycles in a Changing Ocean
Lévy, Marina; Couespel, Damien; Haeck, Clément; Keerthi, Madhavan Girijakumari; Mangolte, Ines; Prend, C J (Peer reviewed, 2023)Fine-scale currents, O(1–100 km, days–months), are actively involved in the transport and transformation of biogeochemical tracers in the ocean. However, their overall impact on large-scale biogeochemical cycling on the ... -
Machine learning reveals regime shifts in future ocean carbon dioxide fluxes inter-annual variability
Couespel, Damien; Tjiputra, Jerry; Johannsen, Klaus; Ayar, Pradeebane Vaittinada; Jensen, Bjørnar (Peer reviewed; Journal article, 2024)The inter-annual variability of global ocean air-sea CO2 fluxes are non-negligible, modulates the global warming signal, and yet it is poorly represented in Earth System Models (ESMs). ESMs are highly sophisticated and ... -
Stronger Oceanic CO2 Sink in Eddy-Resolving Simulations of Global Warming
Couespel, Damien; Bopp, Laurent; Lévy, Marina (Peer reviewed; Journal article, 2024)Accurately representing the ocean carbon cycle in Earth System Models (ESMs) is essential to understanding the oceanic CO2 sink evolution under CO2 emissions and global warming. A key uncertainty arises from the ESM's ... -
What goes in must come out: the oceanic outgassing of anthropogenic carbon
Couespel, Damien; Tjiputra, Jerry (Peer reviewed; Journal article, 2024)About 25% of the emitted anthropogenic CO2 is absorbed by the ocean and transported to the interior through key gateways, such as the Southern Ocean or the North Atlantic. Over the next few centuries, anthropogenic CO2 is ...
