Delivery of aged terrestrial organic matter to the Laptev Sea during the last deglaciation Open
Arctic warming is causing rapid thawing of permafrost, which holds about 1.25 times as much carbon as currently is present in the atmosphere. The ongoing Arctic warming and projected sea level rise are expected to accelerate permafrost tha…

Ocean control on sea ice in the Nordic Seas Open
To better understand the processes in the Nordic Seas and their connection to large-scale climate changes during Dansgaard-Oeschger (D-O) events, we reconstruct sea ice extent (SIE) and subsurface temperatures (SubSTs) in the eastern Fram …

Enhanced Arctic sea-ice retreat due to pronounced pacificization effect in the Holocene Open
Future climate confronts major challenges due to ongoing Arctic sea-ice retreat. Notably, eventful sea-ice loss in the Holocene appears comparable circumstance, but associated physics remians poorly understood. Here we present a high-resol…

Holocene Terrestrial Permafrost Contributes More Highly Reactive Organic Matter to the Laptev Sea Shelf Than Pleistocene Permafrost Open
Warming can lead to mobilization of organic matter (OM) initially stored in circumarctic permafrost and subsequent greenhouse gas release to the atmosphere. Our understanding remains limited regarding how the extent of carbon release, that…

Geospatial patterns in terrestrial organic matter reactivity across four shelf seas spanning the Eurasian Arctic Open
Organic matter stored in Arctic permafrost represents a key component of the carbon cycle, yet its reactivity across heterogeneous continent-scale permafrost regions remains poorly understood. Here, we leverage the four shelf seas of the E…

Spatial Heterogeneity of Terrestrial Organic Carbon Burial and Degradation in the East Siberian Arctic Shelf Area Open
Climate warming has led to the translocation of a large amount of terrestrial organic carbon (TerrOC) into the Arctic Ocean. The fate of TerrOC varies dramatically in the Arctic shelves, thus introducing uncertainty into the climate‐carbon…

Quantitative Estimates of Younger Dryas Freshening From Lipid δ<sup>2</sup>H Analysis in the Beaufort Sea Open
The leading hypothesis attributes the Younger Dryas (YD) event to a disruption in the Atlantic Meridional Overturning Circulation, driven by meltwater input from North America. Determining the origin, timing, and magnitude of YD freshening…

Sea ice in the Nordic Seas: Greenland stadial to interstadial changes Open
Sea ice conditions in the eastern Fram Strait between 40 and 36.5 ka b2k (thousand years before the year 2000) are reconstructed in detail, based on biomarker analyses. Following extensive sea ice conditions around the Greenland Interstadi…

Quantifying cross-shelf degradation of terrigenous organic carbon in Eurasian Arctic Shelf Seas Open
The permafrost in the Northern Hemisphere holds approximately 50% of the global soil organic carbon, constituting a reservoir that is twice the size of atmospheric carbon storage. Permafrost carbon plays a vital role in governing the globa…
