1. 6. Spatial resolution of methane production and ebullition in Lake Alsta

   University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Evelina Hiltunen; [2021]
   Keywords : methane; ebullition; TN;

   Abstract : Freshwater ecosystems cover about 4 % of the Earth’s surface. Yet they are important components in the global C cycle, as they in addition to their within-lake primary production, receive and process organic matter loads originating from terrestrial environments. The boreal forest biome has the highest density of lakes globally. READ MORE

3. 7. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Diana Jonsson; [2021]
   Keywords : Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

   Abstract : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. READ MORE

4. 8. Gas Emissions from Contaminated Fibrous Sediments in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Fredrik Collin; [2020]
   Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

   Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. READ MORE

5. 9. Variability of summer CH4 and CO2 flux rates in and between three large Swedish lakes : A spatio-temporal field study

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Isak Nilsson; Filip Seifarth; [2020]
   Keywords : Large lakes; Freshwater; Flux chambers; Emissions; Ebullition; Diffusion; Carbon cycle; Carbon budget; Methane budget; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Variability; Spatial; Temporal; Stora sjöar; sötvatten; flödeskammare; utsläpp; bubblor; diffusion; kolcykel; kolbudget; metanbudget; växthusgaser; metan; CH4; koldioxid; CO2; variabilitet; rumslig; tidsmässig;

   Abstract : Understanding of natural greenhouse gas (GHG) cycles is crucial for making GHG budgets, which work as basis in climate change and global warming policy programs. Lakes as a source for GHG activity have only recently been included in global GHG budgets, and most studies of lake GHG flux rates are conducted on lakes <10 km2, which only comprise roughly half of the global lake area—making data of large lake flux rates scarce.

6. 10. Analys av metanflöden från sjön Erken

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Ryan Mintz; [2016]
   Keywords : methane; transfer velocity; flux; waterside concentration; eddy covariance; Nyckelord: metan; utbyteskoefficient; flux; metankoncentration; eddy kovarians;

   Abstract : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. READ MORE
