文摘

We used εNdεNd to track the sediment routing in the Var system over the last 50 kyr. Glaciers are the main driver of the glacial/interglacial cycle of sediment flux. The estimated sediment fluxes are 2.5 times higher during the LGM than today. A major change in turbidite activity and sources is observed between 19 and 16 ka. The glacial sediment transfer to the sea depends on the catchment's characteristics.
