1. 1. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

   Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Thibault Desjonquères; [2022]
   Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

   Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

3. 2. Carbonaceous aerosols and trace metal deposition in high-latitude snow : a comparative study in Sweden and Alaska

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Anika Pinzner; [2019]
   Nyckelord :PM; carbon particles; pXRF; arctic; subarctic; EC OC; LAHM; PSAP; TOT; ICP-MS; filter; contamination; albedo;

   Sammanfattning : This study investigates the advantages and disadvantages of several destructive and non-destructive analytical methods that can be employed to characterize airborne par-ticulate matter (PM) deposited in seasonal snow. To this end, a comparative study was conducted on PM obtained from snowpack surveys in two Arctic/subarctic regions of Northern Sweden and Interior Alaska, USA. LÄS MER

4. 3. Cold Surface Layer Dynamics of Storglaciären, Northern Sweden 2009-2019

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Shunan Feng; [2019]
   Nyckelord :Storglaciären; cold surface layer; cold-temperate transition surface; polythermal glacier; Storglaciären; kallt ytskikt; kall-tempererad is; polyterrmal glaciär;

   Sammanfattning : Storglaciären is a sub-Arctic polythermal glacier in northern Sweden. Twenty years' monitoring of thecold surface layer found that it has lost one third of its total volume of cold ice with an average thinningrate of 0.80 ± 0.24 m·a-1 for the period of 1989-2009. LÄS MER

5. 4. Near-Surface Energy Balance on an Alpine Rock Glacier: Murtèl-Corvatsch

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Luisa Pruessner; [2017]
   Nyckelord :rock glaciers; energy balance; SNOWPACK; permafrost;

   Sammanfattning : This project investigates the near surface energy balance on the Murt`el-Corvatsch rock glacier in the Upper Engadine, Swiss Alps, using the 1D physical SNOWPACK model. A correct representation of the near surface energy balance is important to predict the long term evolution of permafrost below rock glaciers. LÄS MER

7. 5. Californian drought: The processes and factors controlling the 2011-2016 drought and winter precipitation in California

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Pontus Cederholm; [2016]
   Nyckelord :winter precipitation; California; drought; mid-latitude cyclones; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Sammanfattning : The factors and processes controlling winter precipitation in California and the 2011-2016 California drought have been examined in a literature study. The study showed that mid-latitude cyclones are the systems that generate winter precipitation in California. LÄS MER
