1. Carbon Dynamics in Northern Marginal Seas
Sammanfattning : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. LÄS MER
2. Transport, degradation and burial of organic matter released from permafrost to the East Siberian Arctic Shelf
Sammanfattning : Permafrost soils in the Arctic store large quantities of organic matter, roughly twice the amount of carbon that was present in the atmosphere before the industrial revolution. This freeze-locked carbon pool is susceptible to thawing caused by amplified global warming at high latitudes. LÄS MER
3. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf
Sammanfattning : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. LÄS MER
4. Terrestrial organic carbon dynamics in Arctic coastal areas : budgets and multiple stable isotope approaches
Sammanfattning : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. LÄS MER
5. Organic geochemical investigation of sources, transport and fate of terrestrial organic matter in the southeast Laptev Sea
Sammanfattning : 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. LÄS MER
