International audience The thermohaline circulation (THC) is a large scale oceanic circulation driven by density gradients. Its Atlantic component is responsible for a significant part of the northward heat transport of the climate system (Broecker, 1991; Lavin et al., 2003), roughly 1PW over the 6P...
