Recent, very rapid retreat of a temperate glacier in SE Iceland
Iceland’s glaciers are particularly sensitive to climate change, and their margins respond to trends in air temperature. Most Icelandic glaciers have been in retreat since c. 1990, and almost all since 1995. Using ice-front measurements, photographic and geomorphological evidence, we examined the record of ice-front fluctuations of Virkisjökull–Falljökull, a steep high-mass-turnover outlet glac...
متن کاملModelling the 20th and 21st century evolution of Hoffellsjökull glacier, SE-Vatnajökull, Iceland
The Little Ice Age maximum extent of glaciers in Iceland was reached about 1890 AD and most glaciers in the country have retreated during the 20th century. A model for the surface mass balance and the flow of glaciers is used to reconstruct the 20th century retreat history of Hoffellsjökull, a south-flowing outlet glacier of the ice cap Vatnajökull, which is located close to the southeastern co...
متن کاملA continuum model for meltwater flow through compacting snow
Meltwater is produced on the surface of glaciers and ice sheets when the seasonal surface energy forcing warms the snow to its melting temperature. This meltwater can run off the surface in streams or percolate through the porous snow and refreeze, which warms the subsurface through the release of latent heat. We model the percolation process from first principles using a continuum model that i...
متن کاملPrimary succession of soil Crenarchaeota across a receding glacier foreland.
The development of soil archaeal community structures in relation to primary succession in bulk and rhizosphere soil was examined across the forefield of the receding Rotmoosferner glacier in Austria. Using cloning and denaturing gradient gel electrophoresis (DGGE) analysis of reverse transcription polymerase chain reaction (RT-PCR) products of extracted 16S rRNA, archaeal community structure w...
متن کاملOribatid Mites in the Glacier Foreland at Hardangerjøkulen
The Oribatida on 3 moraines (from 1955, 1934 and 1750) near the outlet Midtdalsbreen of Hardangerjøkulen glacier (Norway) were investigated. The highest density of mites was observed on the moraine exposed in 1934 (67 years after the glaciers retreat), while the highest number of species (14) was noted on the oldest moraine (206 years after the glaciers retreat). Two species, Tectocepheus vel...
