Última Observation de la convection profonde en mer d'Irminger sur la période 2002-2015 par les flotteurs Argo. ArchiMer Piron, Anne. The deep convection events are important because they form the intermediate and deep water masses feeding the global circulation. The Labrador Sea is the main site of deep convection in the North Atlantic Ocean and produces the intermediate Labrador Sea Water (LSW). The Irminger Sea was also cited but was forgotten during decades because of the lack of direct observations. This thesis provides the first description of the Irminger Sea deep convection at basin scale, thanks to the Argo data. Three convective events occurred in the Irminger Sea since 2010. During the 2011-2012 winter, the convection reached 1000 m and is explained by the sequence of the Greenland tip jets. The event of the 2013-2014 winter, reaching 1300 m, is characterized by a strong...

Analysis of Argo data obtained during winter 2011–2012 revealed the presence over the Irminger Basin of an exceptionally large number of profiles (41) with mixed layer depths (MLD) exceeding 700 m, which was deep enough to reach the pool of the intermediate Labrador Sea Water located in the Irminger Sea. Four of these profiles exhibited an MLD of 1000 m, which was the maximum value observed for the winter in question. The Argo sampling in the Irminger Sea during that winter, which was 3 to 4 times greater than for the preceding winters, enabled the different phases of the mixed layer deepening down to 1000 m, together with their spatial extents, to be observed for the first time. Two intense convective periods occurred: in late January south of Cape...
