  1. 1. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Lindqvist; [2022]
    Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE

  3. 2. Methane tree stem flux over the course of the spring flood : Spatial and temporal effects in a boreal riparian zone

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elin Berg; [2022]
    Keywords : Methane; tree stem flux; boreal forest; riparian zones; spring flood;

    Abstract : Methane (CH4) tree stem-atmosphere flux is viewed as a new frontier in the global carbon cycle and may be of great importance. The effect on flux from different tree species, forest ecosystems and seasons is still uncertain. READ MORE

  4. 3. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lukas Rehn; [2021]
    Keywords : Boreal catchments; carbon cycling; carbon dioxide; DIC; headwater streams; Krycklan Catchment Study; trend analysis;

    Abstract : 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.

  5. 4. CO2-emissions from rivers and streams : Seasonal variation of pCO2-levels and CO2-fluxes

    University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Author : Emile Vandeburie; [2020]
    Keywords : Eddy Covariance; CO2-flux; air-water gas exchange;

    Abstract : Since the industrial evolution, the CO2-levels have been increasing in a way that’s never seen in the history of the earth. To mitigate and adapt to the happening climate change it is really important to understand the global carbon cycle and each component that plays a role in it. READ MORE

  6. 5. Survey of sulphates in process water of LKAB - Kiruna operation

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik; Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Ebba Videll; [2019]
    Keywords : Sulphate; iron ore mine; process water; anhydrite; laboratory grinding; equilibrium calculations; mass balance;

    Abstract : Sulphate-rich wastewater is an increasing concern for industries as LKAB. The water chemistry of the LKAB Kiruna water system is characterized by high alkalinity, high pH (pH 7.5-9.0) and high concentrations of chemical species and soluble minerals. READ MORE
