ReSuMPTiOn project
ReSuMPTiOn is a project that aims to determine the contribution of kilometric-scale oceanic flow features, known as submesoscale turbulence, in several aspects of the global oceanic circulation known for their importance in regulating the Earth’s climate. To achieve this, realistic numerical simulations of the full 3D oceanic flow in the North Atlantic basin, at ultra-high horizontal and vertical resolution, have been designed and and are currently performed by Ocean Next in close collaboration with the MEOM team at IGE. As such, the so-called eNATL60 configuration (see technical specifications below), based on the NEMO ocean model, has been developed. eNATL60 simulations are presently being performed on the MareNostrum supercomputer of the Barcelona Supercomputing Center, thanks to a 40 million CPU-hour PRACE allocation granted to Ocean Next in april 2018.
