  1. 1. Studies of actinides in a superanoxic fjord

    Författare :Per Roos; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Geology; colloids.; TIMS; pore water; remobilisation; sediments; ultrafiltration; uranium; thorium; americium; plutonium; Anoxic; Framvaren; fjord; physical geography; Geologi; fysisk geografi;

    Sammanfattning : Water column and sediment profiles of plutonium, americium, thorium and uranium have been obtained in the superanoxic Framvaren fjord, southern Norway. The concentrations of bomb test fallout Pu, Am as well as 'dissolved' Th in the bottom water are the highest recorded in the marine environment. LÄS MER

  2. 2. Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord

    Författare :Lena Viktorsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :phosphorus; sediment; anoxia; Baltic Sea; By Fjord; benthic flux;

    Sammanfattning : The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture together with the growth of coastal cities increased the load of phosphorus to the coastal ocean where plankton production flourished.

  3. 3. Spatial distribution and conservation planning of seabed biological diversity

    Författare :Genoveva Gonzalez-Mirelis; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Sammanfattning : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.

  4. 4. Mobilitet och estetik. Nuukfjorden på Grönlands västkust som människornas livsvärld för 4000 år sedan. : Mobility and Aesthetics. The Nuuk Fjord on the west coast of Greenland as a human life-world 4000 years ago

    Författare :Maria Hinnerson-Berglund; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :HUMANIORA; HUMANITIES; Palaeoeskimo; life-world; Nuuk Fjord; Greenland; mobility; aesthetics; style; everyday dialectics.;

    Sammanfattning : The point must be to experience things throughout one’s life in all their glory and wonder (Poul Henningsen) The dissertation deals with newly excavated archaeological finds from the Palaeoeskimos who lived around the Nuuk Fjord on the west coast of Greenland about 4000 years ago. The purpose of the study is to present as full a picture a possible of the whole life-world that was theirs. LÄS MER

  5. 5. Long-term changes in macroalgal vegetation on the Swedish coast : An evaluation of eutrophication effects with special emphasis on increased organic sedimentation

    Författare :Britas Klemens Eriksson; Francisco Xavier Niell Castanera; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Baltic Sea; Eutrophication; Fragmentation; Fucus vesiculosus; Functional group; Gullmar Fjord; Macroalgae; Long-term changes; Reproduction; Sedimentation; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : In this thesis I examine and evaluate the effects of a documented large-scale eutrophication on macroalgal vegetation on the Swedish coast. During the past century the load of nutrients has increased manifold in the Baltic Sea area, increasing primary production and organic sedimentation significantly. LÄS MER
