    Abstract : More than 70% of the Earth is covered by water, and most of the sea floor consists of soft sediments, such as mud, clay and sand. Thus, soft sediments form one of the most important habitats on Earth, with a high diversity of organisms. READ MORE

    Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE

  6. 19. Combining limnology and paleolimnology : a refined understanding of environmental sediment signal formation in a varved lake

    Author : Dominique Béatrice Maier; Christian Bigler; Sebastian Diehl; Jasmine E. Saros; Umeå universitet; []

    Abstract : Paleoclimatic archives, such as lake sediments, extend our understanding of terrestrial and aquatic ecosystem dynamics in relation to climate variability beyond the period covered by instrumental data. In this context, annually laminated (i.e. READ MORE

  7. 20. 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
