Impact of oceanic floods on particulate metal inputs to coastal and deep-sea environments: A case study in the NW Mediterranean Sea

► Assessment of particulate metal fluxes to coastal and deep-sea environments. ► Considerable contribution of oceanic floods to annual scenarios. ► The Gulf of Lion acts as a sink for sediment-bound metals, based on mean scenarios. ► Shelf-exported particles inherit the signature of bottom shelf sediments. ► Environmental impact depends on the frequency and the intensity of oceanic floods.
