Exploitable results – Impact of dense shelf water cascading and open-sea convection in the northwestern Mediterranean during winter 2012, on deep-sea biological activity particle fluxes and sediment dynamics

Result description

Five months after the formation of a massive dense water on the continental shelf and in the deep basin of the Gulf of Lions the water of coastal origin created a distinct bottom layer up to a 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 new observations highlight the role of intense episodes of both dense shelf water cascading and open-sea convection to the progressive modification of the NW Mediterranean deep waters.
