1. 1. Effects of drought on waterchemistry in a boreal streamnetwork

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Enrique Gómez de Salazar Martínez; [2021]
   Nyckelord :: drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

   Sammanfattning : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. LÄS MER

3. 2. Dissolved organic carbon (DOC) : Differences in reactivity amongst water sources to boreal streams in Sweden

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Lukas Eriksson; [2018]
   Nyckelord :Dissolved organic carbon; DOC; Discrete riparian inputs; Resazurin; Resorufin;

   Sammanfattning : The importance of dissolved organic carbon (DOC) to aquatic environments is well established in the scientific community. In boreal landscapes, small streams receive water from headwater lakes, mires, and discrete flow paths that drain riparian soils. LÄS MER

4. 3. Climate change impact on water balance and export of dissolved organic carbon : a sub-catchment modelling approach

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Stina Sandgren; [2017]
   Nyckelord :HYPE; hydrological modelling; DOC; climate change; water balance; specific discharge; hydrology; climate scenarios; carbon cycle; mire catchment; forest catchment; Earth and Environmental Sciences;

   Sammanfattning : Climate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers.

5. 4. Landscape factors related to performance of in-situ sensors for prediction of total phosphorus : a statistical analysis of data from 194 streams in Sweden

   Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

   Författare :Cham Hoang; [2017]
   Nyckelord :surface water monitoring; surrogate parameters; total Phosphorous; turbidity; catchment; land-use; soil type;

   Sammanfattning : Accurate monitoring data of phosphorus concentrations in the water will benefit the evaluation of measures taken to reduce the problems of eutrophication. Today, the quantification of phosphorus loads from diffuse sources involves large uncertainties. LÄS MER

7. 5. Catchment influences on mercury methylation in a peatland chronosequence

   Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

   Författare :Robin Hagblom; [2017]
   Nyckelord :methyl mercury; GIS; northern peatland; mire; watershed; elevation;

   Sammanfattning : Since the beginning of industrialization, emissions of mercury (Hg) from human activities in excess of natural levels have increased depo-sition rates to ecosystems, storage in soils and loading to aquatic envi-ronments. Toxicity to animals, subject to this accumulation, as well as to humans consuming them, are the major concerns driving research on this subject. LÄS MER
