1. The Baltic Sea from the present to future : microbial carbon & nutrient cycling in a changing climate
Abstract : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

2. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments
Abstract : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. READ MORE

3. Sediment transport from source to sink in the Lake Baikal basin : Impacts of hydroclimatic change and mining
Abstract : Different magnitude, intensity and timing of precipitation can impact runoff, hillslope erosion and transport of sediment along river channels. Human activities, such as dam construction and surface mining can also considerably influence transport of sediment and sediment-bound contaminants. READ MORE

5. Landslide of contaminated soil into rivers: Environmental impacts and risks
Abstract : Landslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independently.
