## Welcome to the Marine Environmental Chemistry (CEM) Group collection

The Marine Environment Chemistry (CEM) team focuses on several environmental issues:

1. Characterization and quantification of organic and inorganic elements in the marine environment,
2. Estimation of their flow from the continent to the oceans and their monitoring by optical means,
3. Definition of their sources and fate in the water column,
4. effect of sedimentary diagenesis on anthropogenic inputs.

These themes are a component of the general problem of understanding the cycles of elements and the effect of the anthropization of environments, which are crucial phenomena in the context of global climate change.

### [hal-00873390] Interaction of dense shelf water cascading and open-sea convection in the northwestern Mediterranean during winter 2012

(10/04/2021)
The winter of 2012 experienced peculiar atmospheric conditions that triggered a massive formation of dense water on the continental shelf and in the deep basin of the Gulf of Lions. Multiplatforms observations enabled 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 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.
