1. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard
Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

2. Tolkning av georadarprofiler över grundvattenmagasinet Verveln - Gullringen i Kalmar län
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : I Sverige utgörs majoriteten av våra grundvattenresurser av isälvavlagringar i form av rullstensåsar och isälvsdeltan bestående av sand och grus. Isälvsavlagringarna är utan tvekan de mest betydelsefulla grundvattenförekomsterna för Sveriges dricksvattenförsörjning. LÄS MER
3. Spatial and Temporal Variations in a Perennial Firn Aquifer on Lomonosovfonna, Svalbard
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : A firn aquifer is a type of englacial water storage that forms when surface meltwater fills up the pore space in porous firn. If the retention time exceeds one year the feature is regarded as perennial. The melt and accumulation rates as well as the available pore space determine the formation and extent of the firn aquifer. LÄS MER
4. Non-Destructive testing of concrete with ground penetrating radar
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : Concrete structures are susceptible to deterioration over time and it is vital to continually assess concrete structures to maintain the structural integrity and prolong the service life. In recent years there has been an increased interest in non-destructive testing of concrete, i.e. LÄS MER
5. Stora torget : En geofysisk undersökning med georadar (GPR) av Stora torget i Sigtuna
Kandidat-uppsats, Stockholms universitet/Arkeologiska forskningslaboratorietSammanfattning : This paper contains geophysical analysis of the largest town square in Sigtuna, Sweden. The studied area is approximately 736 m2. The purpose of the study was to search for early medieval house remnants and to possibly find structures matching those found during excavations in other parts of the town. LÄS MER
