  1. 1. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils

    Författare :Karin von Arnold; Leif Klemedtsson; Mats Nilsson; Björn Hånell; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gases; GHG; fluxes of CO2; CH4; drained forests; organic soils; Skogsbotanik; miljöaspekter; växthusgaser; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. LÄS MER

  2. 2. Reducing ships' fuel consumption and emissions by learning from data

    Författare :Fredrik Ahlgren; Marcus Thern; Maria E. Mondejar; Cecilia Österman; Ann-Charlotte Larsson; Erik Dahlquist; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shipping; energy efficiency; orc; machine learning; emissions; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. LÄS MER

  3. 3. Land use effects on greenhouse gas emissions from boreal inland waters

    Författare :Marcus Klaus; Jan Karlsson; Peter Staehr; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; greenhouse gas; boreal forest; carbon cycling; whole-ecosystem experiment; limnology; metabolism; forest clearcutting; nitrogen enrichment;

    Sammanfattning : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. LÄS MER

  4. 4. Greenhouse gas fluxes between drained forested peatlands and the atmosphere - influence of nutrient status and wood ash fertilization

    Författare :Maria Ernfors; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :greenhouse gases; peatlands wood; ash; nutrient status;

    Sammanfattning : The management of peatlands for wood production involves drainage and, sometimes, fertilization with, for example, wood ash. The effects of these measures on greenhouse gas fluxes, in relation to the ... LÄS MER

  5. 5. Microbial mitigation of greenhouse gas emissions from boreal lakes

    Författare :Gaëtan Martin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES;

    Sammanfattning : The climate change crisis has drawn the attention of both the public and scientific community to the carbon cycle and particularly to the importance of greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4). CO2 has been a key component of Earth´s climate regulation throughout its geological history and is now the main driver of the current change in climate. LÄS MER
