Using Argo floats, we show that a major deep convective activity occurred simultaneously in the Labrador Sea (LAB), South of Cap Farewell (SCF) and the Irminger Sea (IRM) during winter 2014–2015. Convection was driven by exceptional heat loss to the atmosphere (up to 50% higher than the climatologic...
