    Abstract : 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. READ MORE

  5. 18. Urban and rural environments from Iron Age to Medieval time in northern Europe : Evidence from fossil insect remains from South-Eastern Sweden and Novgorod, Russia

    Author : Magnus Hellqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Late Holocene; Iron Age; Medieval time; subfossil insects; Coleoptera; environment; climate; human environment; taphonomy; south-eastern Sweden; Novgorod; Geovetenskap; Earth sciences; Geovetenskap; Quarternary Geology; Kvartärgeologi;

    Abstract : This thesis presents and discusses results from studies in of subfossil insect remains of natural and cultural origin. Samples were obtained by coring in sediments or by collection during archaeological excavations. The aim was to reconstruct local environment and climate in rural and early urban situations from Iron Age to medieval time. READ MORE

    Abstract : Uncertainties about the rate and magnitude of future climate change have drawn attention to the climate variability following the Late Glacial-Early Holocene transition, c. 12-8 ka BP. READ MORE

  7. 20. Late Holocene spatiotemporal hydroclimatic variability over Fennoscandia inferred from tree-rings

    Author : Kristina Seftigen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree-rings; Fennoscandia; hydroclimate; SPEI; SPI; ring-width; maximum latewood density; stable isotopes; field reconstruction; point-by-point regression;

    Abstract : There is a broad scientific consensus that the global climate is changing, and that human activity is a significant factor contributing to the change. The response of the hydrological cycle to the warming is far reaching, including increases in the intensification and frequency of extreme hydroclimatological events. READ MORE
