High resolution climatic information from short firn cores, western Dronning Maud Land, Antarctica

Ten meter firn cores were collected during the Swedish Antarctic Expedition to Dronning Maud Land in 1988-89. The oxygen isotope stratigraphy in the cores was used to obtain a proxy-temperature record and a surface accumulation record for the last 15-30 years. The delta 18oxygen record from cores on the ice shelf and the escarpment area, below 2,000 m a.s.l., show high variability and little year-to-year correspondence to each other or with the temperature record from nearby Halley Antarctica.
