International audience Artificially enhanced vertical mixing has been suggested as a means by which to fertilize the biological pump with subsurface nutrients and thus increase the oceanic CO 2 sink. We use an ocean general circulation and biogeo-chemistry model (OGCBM) to examine the impact of arti...
