1. Carbon Dioxide Supersaturation in Lakes – Causes, Consequences and Sensitivity to Climate Change
Abstract : The global carbon cycle is intimately linked with the earth’s climate system. Knowledge about carbon cycling in the biosphere is therefore crucial for predictions of climate change. READ MORE

2. The role of sediments in the carbon cycle of boreal lakes
Abstract : Inland waters are active sites of carbon (C) processing and emitters of carbon dioxide (CO2) and methane (CH4) to the atmosphere. In the boreal zone, where surface waters receive large quantities of organic carbon (OC) from surrounding forests and wetlands, lakes and streams act as strong sources of these greenhouse gases.

3. The origin and fate of sediment organic carbon in tropical reservoirs
Abstract : Recently, the construction of reservoirs has boomed, particularly in the tropics, but the impact of reservoirs on the global carbon cycle is not evident. Reservoirs accumulate sediments that simultaneously bury organic carbon (OC) and thus act as a C sink, and also produce methane (CH4) and thus emit a strong greenhouse gas. READ MORE

4. Organic geochemical investigation of sources, transport and fate of terrestrial organic matter in the southeast Laptev Sea
Abstract : Permafrost carbon stores have been suggested to react to warming trends with increased terrestrial loading to its coastal waters. Presently, the warming has been seen to be especially high in the East Siberian Arctic and the fate of the major release of terrestrial matter to these coasts is yet to be detailed. READ MORE

5. Gas Exchange over Aquatic Interfaces and its Importance for Greenhouse Gas Emission
Abstract : Aquatic ecosystems play a substantial role in global cycling of carbon (C), despite covering only about 4% of the earth surface. They emit large amounts of greenhouse gases (GHG) to the atmosphere, comparable to the amount of C stored annually in terrestrial ecosystems. In addition, C can be buried in lake sediments. READ MORE
