  1. 1. Export and sources of organic carbon in the Lena River basin, Northeastern Siberia

    Author : Liselott Kutscher; Carl-Magnus Mörth; Per Andersson; Don Porcelli; Peter Raymond; Sebastian Sobek; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; organic matter; NOM; DOM; POM; Lena River; organsikt kol; DOC; POC; organiskt material; NOM; DOM; POM; Lenafloden; geokemi; Geochemistry;

    Abstract : Permafrost areas are considered to be one of the largest terrestrial storages of carbon. In a warming climate these areas are expected to experience changes in carbon transport to rivers and the oceans due to permafrost thawing, which could enhance erosion, change water flow pathways and increase greenhouse gas emissions.

    Abstract : Nedbrytbara metaller utgör en ny klass av biomaterial med potential attersätta permanenta material i tillfälliga applikationer. Detta för att minskarisken för långvariga biverkningar. READ MORE

  3. 3. ToF-SIMS as a tool for analysing organic material in geological samples -Fluid inclusions and beyond

    Author : Sandra Siljeström; Jukka Lausmaa; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic material; ToF-SIMS; Other earth sciences; Övrig geovetenskap; geokemi; Geochemistry;

    Abstract : In situ analysis of organic material in rocks has potential to answer questions in geochemistry, astro- and geobiology. Recently, successful studies which included in situ analyses of geological samples with time-of-flight secondary ion mass spectrometry (ToF-SIMS) were carried out. READ MORE

  4. 4. Chlorine Transport in a Small Catchment

    Author : Teresia Svensson; Gunilla Öberg; Katarina Abrahamsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; catchment; chloride; chlorine; chloroform; organic chlorine; runoff water; soil; VOCls; avrinningsområde; avrinningsvatten; flyktiga klorerade föreningar klor; klorid; kloroform; organiskt klor; mark; Water in nature and society; Vatten i natur och samhälle;

    Abstract : De senaste decenniernas forskning har påvisat att en omfattande bildning och nedbrytning av klororganiska föreningar sker i mark. Bildning av sådana föreningar sker genom att klorid binds in i organiskt material. READ MORE

  5. 5. Community and food web assembly on virgin habitat islands - The nunatak saga

    Author : Maria Ingimarsdottir; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; allochthonous material; arthropods; community assembly; corridor; dispersal; Iceland; metacommunity; nunataks; primary succession; stable isotopes.;

    Abstract : The classical view of primary community assembly is that colonisation by plants is essential before invertebrates can establish. It has been recognised, however, that invertebrates can establish before plants, and that they may be important in the first steps of community assembly. READ MORE
