1. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. READ MORE

2. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

3. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?
University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Abstract : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. READ MORE

4. Hydrological and chloride transport processes in a small catchment of the Norrström Basin : a MIKE SHE modelling approach
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Water is ubiquitous on our planet and constitutes a vital part of ecosystems. It supports the life of all beings on the earth while simultaneously evokes water-related issues such as water shortage, water contamination. As UN advocates, a globally shared blueprint for available clean water is depicted in Sustainable Development Goals (SDGs). READ MORE

5. How Do Long-Term Declines in Anthropogenic Sulfur Dioxide Emissions and Sulfate Wet Deposition Compare with Trends in Freshwater Chemistry in Scandinavian Rivers?
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Acidification of precipitation is an important environmental problem that emerged during the past century, especially after the Second World War. Acidification was primarily caused by human-made emissions of SOx (mostly SO2) and NOx, which are oxidized sulfur and nitrogen gases. READ MORE
