2. Effects of Salinization on Lake Metabolism
University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Abstract : With rising salinity levels in many freshwaters across the globe caused by for example sealevel rise and de-icing salts, it becomes important to understand what effect it has on freshwater ecosystems, since the lakes and rivers themselves are important parts in the global carbon cycle. In this study I have looked at what effects increased salinity levels have on different lakes metabolism, specifically oxygen concentration and primary production. READ MORE

3. Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctuations in precipitation, decreases in yearly snow, faster snow melt rates, variability in evapotranspiration due to environmental stress, and related changes in the energy, hydrological, and carbon cycles will change these northern, boreal landscapes is crucial.

4. Data analysis and wake modelling ofthe Lillgrund wind farm
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : This work consists of two parts: the analysis of the operating data collected at Lillgrund between December 2007 and March 2018, and the implementation and evaluation of three wake models. Operational and meteorological data from the Lillgrund wind farm have been analyzed to assess the aerodynamic efficiency and general performance of the farm. READ MORE
