1. 1. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Daniel Estmark; [2022]
   Keywords : Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

   Abstract : 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.

3. 2. Spatial and Temporal Variations in a Perennial Firn Aquifer on Lomonosovfonna, Svalbard

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Monika Hawrylak; Emma Nilsson; [2019]
   Keywords : perennial firn aquifer; ground penetrating radar; Svalbard; Lomonosovfonna; flerårig firnakvifer; georadar; Svalbard; Lomonosovfonna;

   Abstract : 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. READ MORE

4. 3. Non-Destructive testing of concrete with ground penetrating radar

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Elias Hammarström; [2018]
   Keywords : Concrete; Non-destructive testing; Ground Penetrating Radar GPR ; Assessment; Inspection;

   Abstract : 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. READ MORE

5. 4. Reflections in the dark : Ground-penetrating radar surveys for the detection of Viking Age and early medieval harbor remains in Sigtuna, Sweden

   University essay from Stockholms universitet/Arkeologiska forskningslaboratoriet

   Author : Anne Homeister; [2015]
   Keywords : Geophysik; Georadar; Sigtuna; harbor; Viking Age; early medieval; Geofysik; Georadar; Sigtuna; Uppland; hamnar; Draken; Urmakaren; Koppardosan; Borgmästarängen; Vikingatiden; tidig medeltid;

   Abstract : In this thesis a ground-penetration radar survey was carried out in four areas, Borgmästarängen, Draken, Urmakaren and Koppardosan in Sigtuna. The aim of this paper is to detect remnants of the Viking Age harbor at those chosen sites. READ MORE

6. 5. Changes in the Cold Surface Layer on a Polythermal Glacier during Substantial Ice Mass Loss

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Klara Blomdahl; [2015]
   Keywords : Polythermal glacier; digital elevation model; ground-penetrating radar; cold surface layer; Pårteglaciären; northern Sweden; Polytermal glaciär; digital höjdmodell; georadar; kallt ytskikt; Pårteglaciären; norra Sverige;

   Abstract : Climate change in the Arctic and sub-Arctic has induced substantial changes in the inland cryosphere. The warming climate is causing a reduction in glacier size and extent and the average net mass balance for Arctic glaciers have been negative over the past 40 years. READ MORE
