1. Spatial distribution of snow in Antarctica and other glacier studies using ground-penetrating radar
Sammanfattning : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. LÄS MER
2. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet
Sammanfattning : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. LÄS MER
3. Brash Ice and Level Ice Growth, Effects of Snow
Sammanfattning : Brash ice occurs due to frequent navigation in ice-infested waters, typically along established navigation tracks regularly maintained by icebreakers and harbors. The accumulation and consolidation of brash ice between two ship passages are influenced by meteorological factors including the cumulative freezing air temperatures, and the mechanical processes such as ice-breaking due to ship passages.

4. Subsurface fluxes of mass and energy at the accumulation zone of Lomonosovfonna ice cap, Svalbard
Sammanfattning : Glaciers cover ca 10% of the Earth's land and are found in the high altitudes and latitudes. They are important components of environmental systems due to the multiple feedbacks linking them with the atmosphere, hydrosphere and periglacial landscapes. LÄS MER
5. Ground freeze-thaw, snow and roads in northern Sweden
Sammanfattning : In this thesis freeze-thaw along roads in northern Sweden is examined. The examinations are put in a context of changing climate and its amplification towards the Arctic region on earth. The research focuses on the impact of a warmer climate on ground freeze-thaw and in exten- sion road maintenance in the region. LÄS MER
