  1. 6. Arctic Loess as an Environmental Archive: Holocene Dust and Wildfire Record in West Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lars Petter Hällberg; [2018]
    Keywords : aeolian dust; IRSL; luminescence dating; charcoal analysis; magnetic susceptibility; wildfire;

    Abstract : The largest wildfire ever observed in Greenland raged through its tundra during august 2017, and it is unknown if there have been similar wildfires in the area before satellite monitoring began in 1999. Arctic wildfires affect permafrost degradation, carbon storage of soils and the surface albedo of the Greenland Ice sheet – despite this, local fires have previously been ignored by researchers.

  3. 7. Aerosol Input and Snow Accumulation Rates on the Northern Greenland Ice Sheet : Reconstructed by means of Continuous Flow Analysis (CFA) of 6 shallow firn cores

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Patrick Stephan Zens; [2018]
    Keywords : continuous flow analysis; Greenland; shallow firn core; aerosol; snow accumulation; glaciochemistry; kontinuerlig flödesanalys; Grönland; grunda firnkärnor; aerosol; snöackumulering; glaciokemi;

    Abstract : Ice, firn and snow cores from the Greenland ice sheet offer a unique opportunity to reconstruct past climate conditions. These can be analyzed with continuous flow analysis (CFA) in order to acquire proxy information about ancient atmospheric aerosol concentrations, snow accumulation rates or temperature variations, atmospheric composition, solar activity as well as volcanism and biological activity.

  4. 8. Importance of large scale extreme precipitation to the surface mass balance of the Greenland Ice sheet

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Moa Hallberg; [2018]
    Keywords : Ice sheet; Greenland; surface mass balance; atmospheric rivers; Physics and Astronomy;

    Abstract : The ongoing climate change has affected Greenland's ice sheet with heighten near surface temperatures, an extended melt season and change in precipitation. These effects have caused Greenland's ice sheet to melt at an accelerating rate. READ MORE

  5. 9. Methane flux measurements with low-cost solid state sensors in Kobbefjord, West Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Axén; [2016]
    Keywords : Geography; Physical Geography; Arctic; Greenland; methane flux; wetlands; instrument; Earth and Environmental Sciences;

    Abstract : Methane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. READ MORE

  6. 10. Development of a System for Long Term Underwater Sensing

    University essay from KTH/Marina system

    Author : Jari Krützfeldt; [2015]
    Keywords : ;

    Abstract : The monitoring of the worlds oceans is a fundamental requirement to understand and predict the ongoing climate change. Scientists need reliable long-term data series from regions that are of great interest for understanding the climate change and its consequences. READ MORE
