Description
Summary:During the expeditions ARK-VII/1, ARK-VII/3 and ARK-Xl2 sediment cores were taken by "RV Polarstern" from the shelf and the fjords of East Greenland and the Greenland Sea. The magnetic susceptibility and heavy mineral were determined at 48 surface sediment samples from undisturbed box cores. The main objective of this study was the identification of source areas and transport processes of terrigenous sediments at the East Greenland continental margin. The results can be summarized as lollows:1a) Magnetic susceptibility in the North Atlantic is useful to detect delivery regions of the material transported by currents.b) The magnetic susceptibility is controlled by the ferromagnetic particles of the silt fraction.c) There are four important source areas: . The ferromagnetic particles of the box core PS2644-2 are transported from the Iceland Archipelago. . The material from the Geiki-Plateau effects the magnetic susceptibility in the Scoresby Sund Basin. . The magnetic susceptibility in the shelf regions in the ... : Supplement to: Grafenauer, Ingo (1998): Terrigener Sedimenteintrag am Ostgrönländischen Kontinentalrand - Rekonstruktion anhand von Schwermineraldaten.
