  2. 2. Importance of bacterial maintenance respiration and baseline respiration for development of coastal hypoxia

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Kevin Vikström; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Respiration; Estuarine; Allochthonous; Maintenance; primary production; bacterial production;

    Sammanfattning : Reduced oxygen concentrations and increasing hypoxic zones havebecome more common in the sea due to climate change andeutrophication. The main cause of oxygen loss in oxygenatedenvironments is respiration. LÄS MER

  3. 3. Carbon metabolism in clear-water and brown-water lakes

    Detta är en avhandling från Umeå : Institutionen för ekologi, miljö och geovetenskap, Department of Ecology and Environmental Sciences

    Författare :Jenny Ask; Umeå universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; clear-water lakes; brown-water lakes; primary production; bacterial production; benthic; pelagic; net ecosystem production; allochthonous organic carbon; CO2; DOC; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Limnisk ekologi; limnologi; Limnology; naturgeografi; Physical Geography;

    Sammanfattning : The trophic state of lakes is commonly defined by the concentration of nutrients in the water column. High nutrient concentrations generate high phytoplankton production, and lakes with low nutrient concentrations are considered low-productive. LÄS MER

  4. 4. Primary Marine Aerosol Production Studies using bubble-bursting experiments

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Kim Hultin; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sea spray; water temperature; dissolved oxygen; photosynthesis; bacterial emissions; V-TDMA; mixing state; eddy covariance; NATURAL SCIENCES; NATURVETENSKAP; tillämpad miljövetenskap; Applied Environmental Science;

    Sammanfattning : Aerosol particles affect the Earth’s climate, although their impact is associated with large uncertainties. Primary marine aerosol represents a significant fraction of the global aerosol budget considering the Earth’s 70-percentage coverage by oceans. LÄS MER

  5. 5. A passage to wastewater nutrient recovery units Microalgal-Bacterial bioreactors

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Anbarasan Anbalagan; Mälardalens högskola.; [2018]
