  2. 1. Geochemistry of coastal Baltic sediments : processes and sampling procedures

    Author : Sven Blomqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Quantitative and experimental studies on Recent sedimentary processes, with particular reference to element dynamics and mass transport, were conducted in a coastal area of the north-western Baltic proper. A five-year geochemical study reports sediment trap catches, and estimates the flux dynamics of resuspended sediments and primary settling matter. READ MORE

  4. 2. Molecular and isotopic characterization of terrestrial organic carbon released to (sub-)Arctic coastal waters

    Author : Jorien Elisabeth Vonk; Örjan Gustafsson; Jason Neff; Stockholms universitet; []
    Keywords : organic carbon; terrestrial biomarkers; radiocarbon; particulate organic carbon; sediments; sphagnum; Arctic; Bothnian Bay; East Siberian Sea; Kalix River; Kolyma River; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Arctic soils store half of the global soil organic carbon (OC) pool and twice as much C as is currently present in the atmosphere. A considerable part of these carbon pools are stored in permafrost. READ MORE

  5. 3. Sediment sources and transport pathways, Lithuanian coastal zone

    Author : Milda Kairytè; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

    Abstract : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. READ MORE

  6. 4. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Author : Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. READ MORE

  7. 5. Coastal signals of environmental changes: foraminifera as benthic monitors

    Author : Inda Brinkmann; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; benthic foraminifera; proxy calibration; trace element geochemistry; environmental DNA; deoxygenation; drought; coastal environments;

    Abstract : Climate changes, tightly linked to anthropogenic activities, are significantly altering environments and ecosystems globally, such as by increasing marine and coastal deoxygenation or occurrences of extreme weather events. The significance of paleoenvironmental and -climate reconstructions, as well as monitoring of current conditions, for unravelling baseline natural variation, today’s changes and potential future impacts, has been recognised by the Intergovernmental Panel on Climate Change (IPCC) reports.
