16. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.

17. Water quality and organic matter linkages in waters draining arable fields
University essay from SLU/Dept. of Soil and EnvironmentAbstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

18. Spruce Forests and Peat Wetlands in Lake Bolmen’s Catchment Both Leak and Degrade Coloured Dissolved Organic Carbon
University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhetAbstract : Lake browning in the northern hemisphere is endangering crucial ecosystem services. Darker water decreases fish and primary production as well as touristic and recreational values. It furthermore requires intensive treatment to receive safe drinking water. Brownification is connected to iron and coloured dissolved organic carbon (DOC). READ MORE

19. Initial nutrient retention capacity in a constructed wetland : Evaluating the effectiveness of a newly constructed wetland to reduce eutrophication symptoms in a Baltic Sea bay in northern Sweden
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Since the turn of the last century, a substantial increase in nutrient load to the Baltic Sea is apparent. Adding the ongoing environmental change with raising temperatures and increased precipitation, this will continue to have a prominent environmental impact on our coastal ecosystems, especially in northern latitudes.

20. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.
