1. Microalgae for Phosphorus Removal from Wastewater in a Nordic Climate
Abstract : As part of a research project aiming to develop and evaluate a hydroponic system for wastewater treatment in Sweden, extended nutrient removal by microalgae was tested. The hydroponic/microalgal wastewater treatment system was built in a greenhouse in order to improve growth conditions for plants and algae. READ MORE

2. The role of nutrients for stream ecosystem function in Arctic landscapes : drivers of productivity under environmental change
Abstract : Arctic and sub-Arctic freshwaters are currently experiencing substantial ecosystem changes due to the effects of global warming. Global warming effects on these freshwaters include increasing water temperatures, altered hydrological patterns, shifts in riparian vegetation and changes in the export of nutrients and carbon from soils.

3. Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene : Insights from biomarkers and climate model simulations
Abstract : Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e. READ MORE

4. Microalgae at wastewater pond treatment in cold climate : an ecological engineering approach
Abstract : Three types of wastewater ponds in subarctic climates were investigated, each of them highly dependent on microalgae. They were fellingsdams, i.e. READ MORE

5. Investigations of the influence of physical factors on some marine ecological systems
Abstract : This thesis is about the conditions for life in the sea. The marine life forms may look disparate, but are joined by their common dependence of the fluid medium which they inhabit. The motion and the properties of the water in the sea largely determine the conditions with which all maritime organisms have to comply. READ MORE
