(1988): Accumulation and ice core-studies on Filchner-Ronne Ice Shelf, Antarctica. Annals of Glaciology, 11, 23-31, hdl:10013/epic.25953.d001}, abstract={Accumulation rates in the eastern part of Ronne Ice Shelf were determined by isotopic stratigraphy (18O). The samples were taken from snow-pits dug during the Filchner I and II operations in 1984 and 1986. In general, the accumulation rate decreases towards the south; the greatest decrease, from 21.3 to 13.3 g/cm$\ast$$\ast$2/a, was observed between Filchner Station and measuring point 341, sited 270 km up-stream of the ice edge. The d18O values of the near-surface layers vary between -25 and -29 per mil. The 18O content in the more southerly part is progressively depleted in the direction of M\"{o}llereisstrom, paralleling a decrease in the accumulation rate. Near the ice edge the 18O content decreases to the west. A 100 m ice core drilled in 1984 at point 340, 22 km from the ice edge, probably goes back to A.D. 1460; it has been dated by isotopic stratigraphy.\\ The accumulation rate up-stream of the drilling site was deduced from the sequence of annual layers, using a simple ice-flow model. The accumulation shows strong variations over the last 200 years, which may be caused in part by local variations in the accumulation on Ronne Ice shelf.}, type={data set}, publisher={PANGAEA} }
