  2. 6. Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach

    Author : Johan Striberger; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Iceland; the Holocene; lake sediments; varves; glacial meltwater variability; surge periodicity; palaeoclimate;

    Abstract : The North Atlantic region has experienced significant climate fluctuations during the Holocene. It has been shown that these fluctuations affected the terrestrial environment in Iceland, including its glaciers and ice caps. READ MORE

  4. 7. Quantitative controls on the routing of supraglacial meltwater to the bed of glaciers and ice sheets

    Author : Caroline Clason; Douglas Mair; Peter Nienow; University of Aberdeen Geography and Environment; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glaciers Greenland Moulins Supraglacial Crevasses Modelling; geografi med naturgeografisk inriktning; Geography; Physical Geography; Hydrology; hydrologi;

    Abstract : The influence of seasonal influx of supraglacial meltwater on basal water pressures and consequent changes in ice surface velocity has been a focus of research spanning over three decades, particularly focussing on alpine glaciers. Now, with increased recognition for a need to better include glacial hydrology within models of ice dynamics and ice sheet evolution, the ability to predict where and when meltwater is delivered to the subglacial system is paramount, both for understanding the dynamics of alpine glaciers, and of large Arctic ice masses.

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

    Author : Shiyong Yu; Kvartärgeologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Porous pavement in a cold climate

    Author : Magnus Bäckström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Local disposal of stormwater can be achieved by using porous pavements instead of impermeable pavements with conventional stormwater pipes and manholes. The objective of this thesis was to analyse the performance of porous pavements during freezing, thawing, and snowmelting conditions in order to evaluate if the porous pavement is suitable for stormwater management and road construction in cold climate regions.

  7. 10. Source and age of late Quaternary loess deposits in Europe

    Author : Yunus Baykal; Thomas Stevens; Christian Zdanowicz; Bryan C. Lougheed; Phillip L. Gibbard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturgeografi; Physical Geography;

    Abstract : Atmospheric mineral dust is a fundamental component of the Earth’s climate system, with dust both responding to and driving climate change. This close link between dust and climate is recorded in archives of past dust activity, which show that abrupt 101-3 yr shifts in temperature during the last glacial period were accompanied with fluctuations in dust activity.
