A record of Holocene hydrological changes has been produced from variations in oxygen-isotope composition (δ 18 O) preserved in freshwater lake sediments from maritime Antarctica. Small amounts (<5%) of authigenic carbonate have been extracted from a non-marl sediment core from Sombre Lake, Signy...
