Résumé : Climatological records from the Amundsen-Scott Station, South Pole, show the summer 1957-1958 to be characterized by periods of exceptionally warm air temperature and above normal snow accumulation. The firn layer deposited during this summer displays an exceptionally high oxygen-18 content, as revealed by 18O/16O ratio profiles obtained by Epstein et al. [6,7] and by us in five pits dug along-side accumulation stakes. © 1966.
