  1. 1. 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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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.

  2. 2. The 200-year history of nss-SO42- concentration in snow and ice from Lomonosovfonna, Svalbard

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maria Schoeps; Josefin Andersson; [2015]
    Nyckelord :Sulfate; nss-SO42-; ice-cores; glaciochemistry; Lomonosovfonna; Sulfat; nss-SO42-; isborrkärnor; iskemi; Lomonosovfonna;

    Sammanfattning : Environmental scientists use ice-core records to reconstruct past atmospheric conditions. Anthropogenic and natural sources of emissions can be traced when analyzing ions in the ice, which is included in the science of glaciochemistry. Sulfate is an excellent ion to use in these studies since it is traceable to these emissions. LÄS MER
