1. Silicon cycling in the Baltic Sea : Trends and budget of dissolved silica
Sammanfattning : The dissolved silicon (DSi) has a crucial role for growth of a large group of primary producers – diatoms and, hence, impact on functioning of the aquatic food web. This thesis contributes to an increased understanding of the modifications of the DSi cycling in the Baltic Sea. LÄS MER
2. Terrestrial Si dynamics in the Arctic: a study on biotic and abiotic controls
Sammanfattning : Silicon is the next most abundant element in the Earth’s crust and its biogeochemical cycle is linked with that of carbon. Further, silicon is a beneficial nutrient for plants in terrestrial ecosystems and a key nutrient for diatoms in aquatic ecosystems. LÄS MER
3. Integrating fluvial processes into the global Si cycle
Sammanfattning : Silicon (Si) is ubiqutious in natural waters as dissolved silica (DSi) and is used as a nutrient by many plant and animal species. DSi ultimately derives from the weathering of silicate minerals, a process which also consumes atmospheric CO2 and couples the silicon and carbon cycles. LÄS MER
4. Marine silicon cycle through the Cenozoic
Sammanfattning : Silicon (Si) cycle is one of Earth's major biogeochemical cycles. Furthermore, the dissolved form of Si (DSi) is an essential nutrient for both terrestrial and marine ecosystems. LÄS MER
