  3. 2. Submerged Landscapes in the Hanö Bay : Early Holocene shoreline displacement and human environments in the southern Baltic Basin

    Författare :Anton Hansson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; Submerged landscapes; Baltic Sea; Southern Sweden; Geoarchaeology; Mesolithic; Early Holocene; Environmental reconstruction; Shoreline displacement;

    Sammanfattning : During times of lower global sea level, vast areas of the coastal shelf were exposed and converted into ecologically diverse coastal landscapes that wereattractive for human occupation. The landscapes were subsequently flooded during the deglaciation, but well-preserved remains of these landscapes andtheir inhabitants can today be found on the seafloor. LÄS MER

  4. 3. The Earth : climate and anthropogenic interactions in a long time perspective

    Författare :Jörgen Olofsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; anthropogenic; climate change; land use; biodiversity; carbon; dynamic global vegetation model; Holocene; pre-industrial; pollen; bison;

    Sammanfattning : The Earth is a highly complex and dynamic system. Life has shaped the entire planet and evolved in response to living conditions. Ecosystems are heavily affected by climate. Rapidly changing conditions imply considerable stress on several species and ecosystems, as well as to the most dominant species on the planet. LÄS MER

  5. 4. Modelling the early to mid-Holocene Arctic climate

    Författare :Marit Berger; Arne Johansson; Rodrigo Caballero; KTH; []
    Nyckelord :Arctic; early Holocene; mid-Holocene; climate modelling; paleoclimate; sea ice; climate change;

    Sammanfattning : In the recent past it has become evident that the Earth's climate is changing, and that human activity play a significant role in these changes. One of the regions where the ongoing climate change has been most evident is in the Arctic: the surface temperature has increased twice as much in this region as compared to the global average, in addition, a significant decline in the Arctic sea-ice extent has been observed in the past decades.

  7. 5. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits

    Författare :Johannes Edvardsson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

    Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER
