TIC: Total inorganic carbon content of bulk sediment material (University of Cologne, Germany)TOC: Total organic carbon content of bulk sediment material (University of Cologne, Germany)D13C_org. Carbon isotope composition of bulk organic matter (British Geological Survey, UK)234U/238U: (234U/238U) activity ratio of detrital matter; samples treated to remove any non-detrital matter (calcium carbonates, organic matter, Mn/Fe oxides) and uranium adsorbed to mineral surfaces prior to analyses (University of Wollongong, Australia)Surface area: Surface area in m2/g describes the total surface area of all mineral grains per gram sediment material, analyzed by means of gas sorption analyses of detrital matter (University of Wollongong, Australia)Tres: Sediment residence time accounts for the time elapsed between the formation of detrital matter <63µm by chemical and physical weathering and final deposition, and thus encompasses the time of detrital matter storage in the weathering horizon and fluvial transport
