  1. 11. The role of deep hydrocarbons in the global hydrocarbon budget

    Författare :Daniil Kudryavtsev; Vladimir Kutcherov; Kostya Trachenko; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrocarbons; non-methane volatile hydrocarbons; carbon dioxide; methane; ethane; propane; butane; global warming; diamond-anvil cells; Raman spectroscopy; high pressure; high temperature; phase transition; Energy Technology; Energiteknik;

    Sammanfattning : Nowadays, the issue of global warming and related environmental problems got widespread awareness among scientific society, politics, the industry as well as it has affected our everyday life. The reason for such a negative impact on the atmosphere is attributed mainly to human activities. LÄS MER

  3. 12. The functional potential of methane producing and consuming microorganisms in a changing world : Den funktionella potentialen hos mikroorganismer som producerar och förbrukar metan i en föränderlig värld

    Författare :Joel White; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Methane; Metagenomics; Peatlands; flux; carbon dioxide; chamber measurements; stable isotope analysis; Eriophorum vaginatum; Calluna vulgaris; climate change; Captured metagenomics;

    Sammanfattning : It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. LÄS MER

  5. 14. Carbon Emissions from Western Siberian Inland Waters

    Författare :Svetlana Serikova; Jan Karlsson; Oleg S. Pokrovsky; Hjalmar Laudon; Peter Raymond; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon; carbon dioxide; methane; carbon emissions; river; lake; inland waters; permafrost; Siberia; Limnology; limnologi;

    Sammanfattning : Inland waters (i.e. rivers, streams, lakes, ponds) emit carbon (C) into the atmosphere. The magnitude of global inland water C emission has been estimated to equal the global ocean C sink, thus making inland waters an important component of the global C cycle. LÄS MER

  7. 15. Carbon sequestration processes in tropical seagrass beds

    Författare :Liberatus Dominick Lyimo; Mats Björk; Martin Gullström; Mariam Hamis; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Carbon sequestration; Carbon sink; Eutrophication; Productivity; Nitrous oxide; Methane; Greenhouse gases; Tropical; Eastern Africa; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows may play a substantial role in climate change mitigation as they are capable to sequester and store substantial amounts of anthropogenic carbon in plant biomass and, more importantly, in their underlying sediments. In this PhD thesis, the carbon-burial potential was assessed by quantifying the amount of organic carbon stored in different seagrass meadows, each dominated by one of the four major seagrass species in the Western Indian Ocean region.
