    Sammanfattning : We are made of stardust in the sense that most atomic nuclei around us have been formed by stars. Stars synthesise new elements and expel them to the interstellar medium, from which later new generations of stars are born. We can map this chemical evolution by analysing the atmospheric contents of old Galactic halo stars. LÄS MER

  7. 5. Sulfur in polar ice and snow : Interpretations of past atmosphere and climate through glacial archives

    Författare :Ulf Jonsell; Margareta Hansson; Mark Curran; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice cores; aerosols; sulfate; methanesulfonate; sulfur isotopes; climate; glacial cycles; Antarctica; Greenland; Physical geography; Naturgeografi;

    Sammanfattning : Snow contains information on the atmosphere it is deposited from. This information is stored in polar ice sheets (Antarctica and Greenland), which are unique geochronological archives of past climate and atmospheric composition. On time scales from annual to glacial cycles, this thesis deals with the signals of sulfur compounds in these archives. LÄS MER
