Surface albedo is a key variable controlling solar radiation absorbed at the Greenland Ice Sheet (GrIS) surface and, thus, meltwater production. Recent decline in surface albedo over the GrIS has been linked to enhanced snow grain metamorphic rates, earlier snowmelt, and amplified melt– albedo feedback from atmospheric warming. However, the importance of distinct surface types on ablation area ...

This paper presents latest results from the combined use of SAR (Synthetic Aperture Radar) remote sensing and GIS providing detailed insights into recent volcanic activity under Vatnajökull ice cap (Iceland). Glaciers atop active volcanoes pose a constant potential danger to adjacent inhabited regions and infrastructure. Besides the usual volcanic hazards (lava flows, pyroclastic clouds, tephra...

Arctic lakes are exposed to warming during increasingly longer ice-free periods and, if located in glaciated areas, increased inflow of meltwater and sediments. However, direct monitoring how...

Measuring pH in glacial meltwaters is challenging, because they are cold, remote, subject to freeze-thaw cycles and have low ionic strength. Traditional methods often perform poorly there; glass electrodes high drift long response times, spectrophotometric techniques unpractical remote environments. Ion selective field effect transistor (ISFET) sensors a promising alternative, proven marine ind...
