  1. 16. Environmental and hydrogeological geophysics with applications in Thailand, Laos, and Sweden

    Författare :Kamhaeng Wattanasen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geophysics; Tillämpad geofysik;

    Sammanfattning : This thesis presents applications of geophysical methods in the fields of environment and hydrogeology. In relation to environmental problems, two different geophysical surveys have been carried out; one to study an arsenic contaminated area in the southern Thailand (paper I) and a second to locate shallow faults in Quaternary sediments in an area around the Ongkharak Nuclear Research Centre, central Thailand (paper II).

  3. 17. Blue Oceans with Blue Mussels - Management and planning of mussel farming in coastal ecosystems

    Författare :Per Bergström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal management; Mytilus edulis; Growth; Planning; Modelling; Predict; Restoration; Mitigation; Aquaculture; Bioturbation;

    Sammanfattning : Eutrophication is one of the largest and most serious global threats to the marine environment. The effect of eutrophication has become increasingly clear during recent time, and major economic and political efforts are being made to tackle its causes and consequences in Sweden and its surrounding seas.

  4. 18. Molluscs, Environment and Man - A Bioarchaeological Approach in Sweden

    Författare :Birgitta M. Johansson; Birgit Arrhenius; Urve Miller; David S. Reese; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; molluscs; role of shells; shell use; bioarchaeology; subfossil shells; environmental indicator; molluscs as food; personal ornaments; ethnography; Björkö-Birka.; Archaeology subjects; Arkeologiämnen;

    Sammanfattning : The thesis aims to examine the role and use of molluscs in Swedish prehistory, in chorological and chronological aspects. Molluscs live in the sea, fresh water and on land. The Swedish mollusc fauna contains 623 taxa: 417 marine, 85 limnic and 121 terrestrial species. LÄS MER

  5. 19. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

    Författare :Olivia Langhamer; Anders Berglund; Jan Sundberg; Andrew Gill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; Biology; Biologi; Animal Ecology; Zooekologi;

    Sammanfattning : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

  7. 20. Immunotoxicology in Marine Invertebrates - Effects of Manganese on Immune Response

    Författare :Carolina A. M. Oweson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Invertebrates; Immune system; Haemocytes; Manganese Mn ; Immunotoxicology; Crustacea; Mollusca; Echinodermata;

    Sammanfattning : Manganese, Mn, is an abundant element in nature, particularly in soft bottom sediments of the oceans and in bedrock. The metal is predominantly bound to the sediment in the colloid state, MnO2. LÄS MER
