Freshwater and sea ice in the Arctic Ocean (AO) both respond to climate forcing but changes in their distribution may in turn also significantly affect Northern Hemisphere climate. The exact mechanisms controlling their transport are, however, still subject of ongoing research. Radiogenic neodymium (Nd) isotopes (expressed as eNd) and rare earth elements (REEs) have successfully been used to trace ocean circulation in the AO and can provide valuable information on the origin, transport and fate of Arctic freshwater and drifting sea ice. Here, we present first sea-ice data and discuss the applicability of these tracers to determine the pathways of Siberian freshwater and the source areas of Arctic sea ice within the Eurasian Basin. Freshwaters originating from various Siberian rivers are well mixed and diluted prior to their advection to the central AO and the Fram Strait, thereby inhibiting the assessment of the individual contributions of the different rivers for these regions. Recent investigations of ... : Supplement to: Laukert, Georgi; Frank, Martin; Hathorne, Ed C; Krumpen, Thomas; Rabe, Ben; Bauch, Dorothea; Werner, Kirstin; Peeken, Ilka; Kassens, Heidemarie (2017): Pathways of Siberian freshwater and sea ice in the Arctic Ocean traced with radiogenic Neodymium isotopes and rare earth elements.
