11. 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

12. Role of sediment organic matter quality and benthic organisms for the fate of organic contaminants in marine systems
Abstract : Marine sediments constitute important contaminant sources within our environment. Organic matter input to marine sediments changes seasonally in terms of both quantity and quality, and has been profoundly altered in many coastal areas due to eutrophication. READ MORE

13. Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord
Abstract : The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture together with the growth of coastal cities increased the load of phosphorus to the coastal ocean where plankton production flourished.

14. Eastern equatorial Pacific bulk sediment properties and paleoceanography since the late Neogene
Abstract : Reconstructing eastern equatorial Pacific (EEP) oceanography since the late Neogene (about 8 million years ago, Ma) is a central topic in current paleoceanographic investigations. The reason for this is two-fold. READ MORE

15. Molecular analysis of lake-sediment organic matter : long-term dynamics and environmental implications in boreal lakes
Abstract : Lake sediment organic matter is material composed of residues from plants, algae, animals, fungi and bacteria. Its molecular composition is dependent on the sources as well as secondary biotic and abiotic transformations, which combined generates a highly complex matrix. READ MORE
