摘要:Abstract(#br)Destabilization and degradation of permafrost carbon in the Arctic regions could constitute a positive feedback to climate change. A better understanding of its fate upon discharge to the Arctic shelf is therefore needed. In this study, bulk carbon isotopes as w...

摘要:Abstract(#br)Ongoing permafrost thaw in the Arctic may remobilize large amounts of old organic matter. Upon transport to the Siberian shelf seas, this material may be degraded and released to the atmosphere, exported off‐shelf, or buried in the sediments. While our understan...

摘要:Abstract(#br)Black carbon (BC) plays an important role in carbon burial in marine sediments globally. Yet the sequestration of BC in the Arctic Ocean is poorly understood. Here we assess the concentrations, fluxes, and sources of soot BC (SBC)—the most refractory component o...

摘要:Abstract(#br)Climate warming is expected to destabilize permafrost carbon (PF‐C) by thaw‐erosion and deepening of the seasonally thawed active layer and thereby promote PF‐C mineralization to CO2 and CH4. A similar PF‐C remobilization might have co...

摘要:Pleistocene ice complex permafrost deposits contain roughly aquarter of the organic carbon (OC) stored in permafrost (PF) terrain. Whenpermafrost thaws, its OC is remobilized into the (aquatic) environment whereit is available for degradation, transport or burial. Aquatic or...

摘要:Recent Arctic studies suggest that sea ice decline and permafrostthawing will affect phytoplankton dynamics and stimulate heterotrophiccommunities. However, in what way the plankton composition will change as thewarming proceeds remains elusive. Here we investigate the chemi...

摘要:The Siberian Arctic Sea shelf and slope is a key region for the degradationof terrestrial organic material transported from the organic-carbon-richpermafrost regions of Siberia. We report on sediment carbon mineralizationrates based on O2 microelectrode profiling;...

摘要:Thawing of permafrost carbon (PF-C) due to climate warming canremobilise considerable amounts of terrestrial carbon from its long-termstorage to the marine environment. PF-C can be then be buried in sediments orremineralised to CO2 with implications for the carbon...

摘要:Ongoing global warming in high latitudes may cause an increasing supply ofpermafrost-derived organic carbon through both river discharge and coastalerosion to the Arctic shelves. Mobilized permafrost carbon can be eitherburied in sediments, transported to the deep sea or deg...

摘要:Abstract(#br)Ongoing rapid arctic warming leads to extensive permafrost thaw, which in turn increases the hydrologic connectivity of the landscape by opening up subsurface flow paths. Suspended particulate organic matter (POM) has proven useful to trace permafrost thaw signa...
