Abstract:
Rare earth element (REE) concentrations and radiogenic isotopes (Sr-Nd-Hf) retrieved from bulk sediment leachates, together with bulk and clay mineralogical signatures, were studied on two piston cores recovered in the Canadian Beaufort (AMD0214-02PC) and Chukchi-Alaskan (HLY0501-01JPC) margins to investigate changes in the weathering regimes and deep-water circulation during the Holocene.
