Description
Summary:In this paper, we summarize data on terrigenous sediment supply in the Kara Sea and its accumulation and spatial and temporal variability during Holocene times. Sedimentological, organic-geochemical, and micropaleontological proxies determined in surface sediments allow to characterize the modern (riverine) terrigenous sediment input. AMS-14C dated sediment cores from the Ob and Yenisei estuaries and the adjacent inner Kara Sea were investigated to determine the terrigenous sediment fluxes and their relationship to paleoenvironmental changes. The variability of sediment fluxes during Holocene times is related to the post-glacial sea-level rise and changes in river discharge and coastal erosion input. Whereas during the late/middle Holocene most of the terrigenous sediments were deposited in the estuaries and the areas directly off the estuaries, huge amounts of sediments accumulated on the Kara Sea shelf farther north during the early Holocene before about 9 cal kyr BP. The maximum accumulation at that time ... : Supplement to: Stein, Ruediger; Dittmers, Klaus Hauke; Fahl, Kirsten; Kraus, Matthias; Matthiessen, Jens; Niessen, Frank; Pirrung, Michael; Polyakova, Ye I; Schoster, Frank; Steinke, Tatjana; Fütterer, Dieter K (2004): Arctic (palaeo) river discharge and environmental change: evidence from the Holocene Kara Sea sedimentary record.
