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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

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

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

    Author : Luisa Pruessner; [2017]
    Keywords : rock glaciers; energy balance; SNOWPACK; permafrost;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  5. 5. Remote sensing-based monitoring of snow cover dynamics and its influence on vegetation growth in the Middle Atlas Mountains

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nezha Acil; [2016]
    Keywords : grasslands; shrublands; forests; Morocco; mountains; monitoring; remote sensing; MODIS; snow; vegetation; Physical Geography; Ecosystem analysis; GIS; Earth and Environmental Sciences;

    Abstract : Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this effect by comparing snow-fed and non-snow-fed sites.
