Eolian versus fluvial supply to the northern Arabian Sea during the Holocene based on Nd isotope and geochemical records

•Authigenic εNd record from North-Eastern Arabian Sea followed the Holocene sea level curve.•Mid-Holocene shift in the εNd record indicates enhanced eolian and/or reduced fluvial supply.•This shift in weathering/erosion supply is attributed to sea level rise and week monsoon.•Sea level change and climate forcing controlled past nutrient supply and chemical weathering fluxes.
