4. 3. Mid-Holocene mineral dust deposition in raised bogs in southern Sweden : Processes and links

   Författare :Jenny Sjöström; Malin Kylander; Carl-Magnus Mörth; Bindler Richard; Lisa Belyea; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paleodust; peat; geochemistry; mineralogy; REE; Holocene; peat accumulation rates; paleostorms; Marine Geology; maringeologi;

   Sammanfattning : Atmospheric mineral dust is a key component of the climate system, which affects insolation, brings nutrients to marine and terrestrial ecosystems, and acts as a cloud condensation nuclei. To reconstruct past patterns in terrestrial dust deposition natural archives may be utilized, such as loess, dunes, lakes, and peat bogs. LÄS MER

5. 4. Reconstruction of Holocene atmospheric mineral dust deposition from raised peat bogs in south–central Sweden

   Författare :Jenny Sjöström; Malin Kylander; Jonatan Klaminder; Martina Hättestrand; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mineral dust; paleodust; peat; Sweden; Holocene; mineralogy; XRD;

   Sammanfattning : Atmospheric mineral dust plays a dynamic role in the climate system acting both as a forcing and a feedback mechanism. To date, the majority of paleodust studies have been conducted on marine sediments or polar ice cores, while terrestrial deposition has been less studied. LÄS MER

7. 5. Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic

   Författare :Karl Ljung; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palynologi; Geology; climate change; pollen analysis; Palaeobotany; phylogeny; palynology; Paleobotanik; fylogeni; vegetation change; gyttja; peat; Holocene; Quaternary; South Atlantic; Tristan da Cunha; physical geography; Geologi; fysisk geografi;

   Sammanfattning : It has been shown that the present interglacial has been climatically dynamic with both rapid and severe climatic fluctuations. The spatial and temporal differences of these changes are however not fully resolved. The aim of this thesis is to present a detail high resolution record of past climate changes from the central South Atlantic. LÄS MER
