  1. 1. Palsa Growth and Decay in Northern Sweden Climatic and Environmental Controls

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Frieda S. Zuidhoff; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; ground thermal properties; palsas; permafrost degradation; peat porosity; Sweden; vegetation.; Geovetenskap; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; naturgeografi; Physical Geography;

    Abstract : This thesis outlines the development and decay of palsas in northern Sweden in relation to climatic and environmental factors. Palsas were investigated on morphology, vegetation, peat porosity, ground temperature and local climate in four bogs situated on a north-south gradient in northern Sweden. READ MORE

  2. 2. Lake sediments around the Antarctic Peninsula archives of climatic and environmental changes

    University dissertation from Umeå : Umeå Universitet

    Author : Rolf Zale; Umeå universitet.; [1993]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lake sediments; Antarctic Peninsula; radiocarbon dating; climatic and environmental changes; sediment chemistry; naturgeografi; Physical Geography;

    Abstract : Lakes and lake sediments from four areas around the Antarctic Peninsula are described.The concentrations of trace metals in sediment are found to be a useful tool in distinguishing between the different sedimentary phases during a transition from marine to limnic environment.

  3. 3. Hydro-climatic changes in irrigated world regions

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Author : Shilpa Muliyil Asokan; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; hydro-climatic change; evapotranspiration; irrigation; water demand; water balance; land-use; water-use; hydrological catchment; Aral Sea; India; Mahanadi River Basin; Physical Geography; naturgeografi;

    Abstract : Understanding of hydro-climatic changes in the world’s river basins is required to ensure future food security. Different regional basins experience different levels of hydro-climatic change depending on the endorheic or exorheic nature of a hydrological basin, along with the climatic conditions and human land and water-use practices, for instance for irrigation.

  4. 4. The Eemian Interglacial at Sokli, northern Finland A multi-proxy environmental and climatic reconstruction based on a 9 m long lacustrine sediment sequence

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Anna Plikk; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Last Interglacial MIS5e ; northern Europe; palaeolimnology; palaeoecology; temperature reconstruction; multiple proxies; climate dynamics; climatic events; Quaternary Geology; kvartärgeologi;

    Abstract : Understanding the fundamentals of the Earth’s climate system during the Quaternary Period (the past ca 2.6 million years) is of imminent interest in light of the reported recent climatic changes. READ MORE

  5. 5. Hydro-Climatic Variability and Change in Central America Supporting Risk Reduction Through Improved Analyses and Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Beatriz Quesada-Montano; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; climate variability; disaster risk reduction; droughts; drought indices; floods; hydrological model; process constraints; statistical downscaling; uncertainty; ungauged basins; water resources.; Hydrology; Hydrologi;

    Abstract : Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme events and their spatio-temporal characteristics. READ MORE
