MARC recordThe characteristics and formation of a High-Arctic proglacial icing / Richard Hodgkins, Martyn Tranter, Julian A. Dowdeswell.
| Title: | The characteristics and formation of a High-Arctic proglacial icing / Richard Hodgkins, Martyn Tranter, Julian A. Dowdeswell. |
| Author(s): | Hodgkins, Richard. Tranter, Martyn. Dowdeswell, Julian A. |

| Abstract: | Describes icing that accumulates over winter between terminus and end moraine of Scott Turnerbreen, Svalbard. Icing is around 750 m long, 50-150 m wide, and 2 m thick. Ground thermal-regime modelling indicates equilibrium permafrost depth of at least 200 m, ruling out extraglacial water as source for icing near to "cold-based" glacier. Discusses evidence for glacial provenance, including water balance, observed extension of icing within east ice-marginal drainage channel, high solute concentrations in icing interstitial water, and estimates of available heat fluxes and hydraulic conductivity. Suggests that winter drainage continues via Darcian percolation through thawed sub-glacial sediments, and that presence of icing is not always reliable indicator of glacier thermal regime. |
