Abstract

This paper presents preliminary findings of a study concerned with icings and related phenomena associated with perennial springs on Axel Heiberg Island. The icings and frost mounds formed by these springs are very different from those formed by late summer and early winter subglacial discharge. The high solute concentrations lead to freezing-point depression, complex patterns of freezing and the formation of brine icings, together with a variety of mineral precipitates. Freezing-point depression experiments help explain icing hydrology and the spatial pattern of icing formation
