  1. 1. DISCO - Drivers and Impacts of Coastal Ocean Acidification

    Detta är en avhandling från Lund University, Faculty of Science, Centre for Environmental and Climate Research (CEC) & Department of Geology

    Författare :Laurie Charrieau; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017-11]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal ocean acidification; Foraminifera; Environmental changes; pH; Salinity;

    Sammanfattning : Ocean acidification, mainly attributed to the increasing anthropogenic CO2 in the atmosphere, is characterised by a lowering pH together with a shift in the sea water carbonate chemistry toward lower concentration of carbonate ions. On the coasts, where the environmental variability is high due to natural and human impacts, ocean acidification mainly affects the frequency, magnitude, and duration of lower pH and lower calcium carbonate saturation events.

  2. 2. Digital technologies as support for learning about the marine environment: Steps toward ocean literacy Digital technologies and ocean literacy

    Detta är en avhandling från Göteborgs universitet

    Författare :Geraldine Fauville; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital technologies; social media; ocean literacy; communication; science education; environmental education; sociocultural theory;

    Sammanfattning : Over the last century the ocean has been negatively impacted by human activities. In order to continue benefitting from marine services and goods, and the qualities afforded to human life through the ocean, citizens need to be informed about their relationship to the ocean and their own impact on it, that is they need to be ocean literate.

  3. 3. Arctic Ocean benthic foraminifera preservation and Mg/Ca ratios Implications for bottom water palaeothermometry

    Detta är en avhandling från Stockholm : Department of Geological Sciences, Stockholm University

    Författare :Natalia Barrientos; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; benthic foraminifera; Mg Ca-temperature; calcite preservation; maringeologi; Marine Geology;

    Sammanfattning : Reconstructions of Arctic Ocean palaeotemperatures are needed to disentangle natural variability from anthropogenic changes and understand the role of ocean heat transport in forcing or providing feedbacks on Arctic climate change. Despite known complications with calcareous microfossil preservation in Arctic Ocean sediments, calcareous benthic foraminifera can be common in interglacial sequences. LÄS MER

  4. 4. Exploring gene expression responses of marine bacteria to environmental factors

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Christofer Osbeck; Linnéuniversitetet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; dissolved organic matter; model bacteria; ocean acidification; organic pollutants; river loadings; transcriptomics; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterioplankton are abundant in marine ecosystems, where they as “masters of transformation” of dissolved organic matter (DOM) are important for energy fluxes and biogeochemical cycles. However, the performance of bacteria in a changing marine environment influenced by anthropogenic activities is poorly understood. LÄS MER
