  1. 1. Stratigraphic and palaeoenvironmental observations in the deposits of a postglacial kettle hole, in the county of Västernorrland

    Master-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

    Författare :Genofeva Eva Kourela; [2020]
    Nyckelord :Multiproxy analysis; palaeoenvironment; minerals; peat accumulation; kettle hole; Coleoptera; environmental archaeology;

    Sammanfattning : The increased human impact on the environment and climate after the retreat of the Last Glacial has strengthened its importance in the region of Västernorrland where Mesolithic sites are evident. This study focuses on a multiproxy analysis, where archaeological and natural science methods are combined to test several techniques in a peat sample. LÄS MER

  3. 2. Evidence for birch forests and a highly productive environment near the margin of the Fennoscandian ice sheet in the Värriötunturit area, northeastern Finland

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Fredrik Bogren; [2019]
    Nyckelord :Early Holocene; productive ice-marginal environment; subarctic birch forests; plant macrofossils; pollen; palaeoenvironmental reconstructions; palaeoclimate reconstructions; Värriötunturit; Kuutsjärvi; northeastern Finland; northern Fennoscandia;

    Sammanfattning : High-resolution records of early Holocene deposits are rare, and as a consequence reconstruction of terrestrial environments very soon after the deglaciation has often been difficult. In this study the palaeoenvironmental conditions of early Holocene (c. 10600-7500 cal. LÄS MER

  4. 3. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Xavier Allègre; [2018]
    Nyckelord :Glacial sedimentology; glaciology; geomorphology; palaeoenvironmental reconstruction;

    Sammanfattning : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

  5. 4. Palaeoenvironmental reconstruction of catchment processes in sediments from Bolgoda Lake, Sri Lanka

    Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Filosofiska fakulteten

    Författare :Frida Eriksson; Daniel Olsson; [2015]
    Nyckelord :Sediment; palaeoenvironmental reconstruction; paleoenvironmental reconstruction; Lake Bolgoda; C:N ratio; TOC; LOI; δ13C; grain size; Sri Lanka;

    Sammanfattning : Bottom sediment is an archive of the historical changes in a lake and its catchment. This thesis is apalaeoenvironmental reconstruction of catchment processes in Bolgoda Lake situated in western SriLanka. We studied a sediment core retrieved from this lake. LÄS MER

  7. 5. Late Holocene palaeoenvironmental reconstruction on a peat sequence from northeastern South Africa, using grass phytoliths as main proxy

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Jenny Sjöström; [2013]
    Nyckelord :Late Holocene; South Africa; Palaeoenvironmental reconstruction; Phytolith; Bokoni;

    Sammanfattning : Contemporary a geographical imbalance of where palaeoclimatological studies have been undertaken exists, where the majority of palaeodata is based on studies from the northernhemisphere. Multiproxy analysis was performed on a peat core from Lydenburg, north-eastern Mpumalanga, covering the last 1.600 years. LÄS MER
