1. Benthic metabolism and sediment nitrogen cycling in Baltic sea coastal areas : the role of eutrophication, hypoxia and bioturbation
Abstract : Eutrophication is one of the greatest threats for the Baltic Sea, and one of its more critical consequences is bottom water hypoxia. Nutrient enrichment and oxygen-depletion affect both the deep central basins and a number of coastal areas, even though strategies for nutrient reduction have lately been implemented. READ MORE

3. Geochemistry of coastal Baltic sediments : processes and sampling procedures
Abstract : Quantitative and experimental studies on Recent sedimentary processes, with particular reference to element dynamics and mass transport, were conducted in a coastal area of the north-western Baltic proper. A five-year geochemical study reports sediment trap catches, and estimates the flux dynamics of resuspended sediments and primary settling matter. READ MORE

4. Hydrogeochemical effects of hydropower regulation on river-aquifer continuum in boreal rivers
Abstract : Hydropower infrastructure affects many large rivers worldwide, threatening riverine and coastal ecosystems by fragmenting flow, disturbing landscapes and water retention and altering sedimentation and primary production. This thesis investigated major impacts of hydropower regulation on hydrological and geochemical processes in large boreal rivers. READ MORE

5. Hydrogeological and geochemical assessment of aquifer systems with geogenic arsenic in Southeastern Bangladesh : Targeting low arsenic aquifers for safe drinking water supplies in Matlab
Abstract : Naturally occurring arsenic (As) in Holocene aquifers in Bangladesh have undermined a long success of supplying the population with safe drinking water. Arsenic is mobilised in reducing environments through reductive dissolution of Fe(III)-oxyhydroxides. READ MORE
