  1. 1. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Författare :Shiyong Yu; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Sammanfattning : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. LÄS MER

  2. 2. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea

    Sammanfattning : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. LÄS MER

  3. 3. Holocene Environmental Change of Southern Öland, Sweden

    Författare :Kerstin Alm Kübler; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Pollen analysis; Öland; Sweden; heath vegetation; landscape history; Fagus; beach ridges; numerical analysis; Geovetenskap; Earth sciences; Geovetenskap; Quarternary Geology; kvartärgeologi;

    Sammanfattning : This thesis describes Holocene environmental change in Ottenby, southern Öland,Sweden. Analyses of pollen sequences collected distally in the Littorina ridge and in fentroughs between lower laying beach ridges show the vegetation history during twoperiods, the first around 8000 BP and the second from 0/500 AD to about present time.

  4. 4. 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; NATURVETENSKAP; HUMANIORA; NATURAL SCIENCES; 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
