  1. 1. Periglacial and glacial landform mapping in the Las Veguitas catchment, Cordillera Frondal of the Andes (Argentina).

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Eirini Makopoulou; [2018]
    Nyckelord :Geomorphological map; thermokarst lakes; glaciers; GIS; Argentinian Andes; spatial and temporal analysis;

    Sammanfattning : The semi-arid and arid Andes of South America are characterized by large areas with glacial and periglacial environments. This study focusses on the distribution of glacial and periglacial landforms in the Las Veguitas catchment, Cordillera Frontal, Argentina. LÄS MER

  3. 2. Change in water surface area northern Sweden

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

    Författare :Femke Pijcke; [2017]
    Nyckelord :Permafrost; thermokarst lakes; climate change; northern Sweden; remote sensing; Earth and Environmental Sciences;

    Sammanfattning : Changes in water surface area (w.s.a.) in Arctic regions have been linked to climate warming and permafrost degradation (Briggs et al. LÄS MER

  4. 3. Spatial distribution and morphometric analysis of thermokarst lakes and other water bodies : Case study from the sporadic permafrost region, Tavvavuoma, Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Christoffer Keskitalo; [2016]
    Nyckelord :thermokarst lakes; permafrost; GIS and remote sensing; change detection analysis; morphometry; Tavvavuoma;

    Sammanfattning : Projected air and ground temperatures are expected to be higher in Arctic and sub-Arcticlatitudes and with temperatures already close to the limit where permafrost can exist,resistance against degradation is low. With thawing permafrost, the landscape is modifiedwith depression in which thermokarst lakes emerge. LÄS MER

  5. 4. Changes in size distribution of lakes in the Nadym catchment, northern Russia

    Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Sara Ahlgren; [2012]
    Nyckelord :Climate change; cryosphere; high latitude areas; Nadym catchment; permafrost hydrology; Russia; thermokarst lakes;

    Sammanfattning : Because of climate change and resource development there is an ongoing increase in the attention directed towards high latitude areas. Over the last years, warming in the Arctic has accelerated quickly. The warming climate can possibly lead to thawing of ground ice, which in turn leads to alterations of the cryosphere. LÄS MER
