Stratigraphic signatures due to flood deposition near the Rhône River: Gulf of Lions,northwest Mediterranean Sea

Episodic flood delivery provides the bulk of the solid discharge for many small to moderate river systems, including the Rhône River in the northwestern Mediterranean. Several recent studies have demonstrated that the fate of this sediment depends on the coherence between river discharge and energetic ocean conditions. The deposition of flood sediment in the ocean can be confirmed by common signatures of episodic discharge events: presence of ⁷Be, physical stratification, and elevated clay content associated with low ²¹⁰Pb activities.
