Multi-platforms observations enabled, with an unprecedented resolution, a synoptic view of dense water formation and spreading at basin scale. Five months after its formation, the dense water of coastal origin created a distinct bottom layer up to few hundreds of meters thick over the central part of the NW Mediterranean basin, which was overlaid by a layer of newly formed deep water produced by open-sea convection. These observations highlight the role of intense episodes of both dense shelf water cascading and open-sea convection to the alteration of the characteristics of the NW Mediterranean deep waters. %G English %L hal-00920704 %U https://hal.science/hal-00920704 %~ CEA %~ INSU %~ METEO %~ MNHN %~ UNIV-PARIS7 %~ X %~ ENS-PARIS %~ UPMC %~ UNIV-TLSE3 %~ UNIV-TLN %~ CNRS %~ UNIV-AMU %~ UNIV-PERP %~ CNES %~ OMP %~ X-DEP %~ MIO %~ OSU-INSTITUT-PYTHEAS %~ LOCEAN %~ LOV %~ UVSQ %~ AGROPOLIS %~ CEFREM %~ PSL %~ UPMC_POLE_3 %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ SU-SCI %~ FR-636 %~ UMS-829 %~ UNIV-PARIS %~ UP-SCIENCES %~ MIO-CEM %~ ENS-PSL %~ MIO-OPLC %~ LOV_OMTAB %~ ALLIANCE-SU %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ IPSL_LOCEAN %~ OMP-LAERO
