We analyzed a high-resolution marine sediment record from the Laptev Sea to reconstruct deglacial permafrost thaw events during the last 16 kyr. Using biomarkers and radiocarbon dating, we found that peaks in pre-aged terrigenous material coincided with rapid sea-level rise, indicating coastal erosion as the main mobilization mechanism. This research provides insights into past permafrost carbon release, informing predictions of future climate-permafrost feedback in a warming world.

Sea ice variability in the eastern Fram Strait between, and within, individual Greenland Stadials and Interstadials is documented by high-resolution proxy reconstructions. Unlike the southeastern Nordic Seas and North Atlantic, these changes were less linked to Greenland climate oscillations. Instead, they were driven by ocean heat transport, regulated by the interplay between the Atlantic Meridional Overturning Circulation strength and sea ice cover in the southeastern Nordic Seas.

The Arctic is warming rapidly, altering carbon storage in Svalbard’s Kongsfjorden. Our study analyzed sediment cores to track organic carbon shifts over time. We found that increasing Atlantic Water inflow enhanced marine carbon while reducing land-derived inputs. These findings suggest that Atlantification is reshaping carbon sequestration in Arctic fjords, with broader implications for the Arctic carbon cycle.

Here, we evaluate the use of biomarkers for reconstructing sea ice between 1880 and 2017 from three sediment cores located in a transect across the Northeast Greenland continental shelf. We find that key changes, specifically the decline in sea-ice cover identified in observational records between 1971 and 1984, align with our biomarker reconstructions. This outcome supports the use of biomarkers for longer reconstructions of sea-ice cover in this region.

Short summary
Short summary
We reconstructed sea ice and organic carbon composition variabilities based on biomarkers and carbon stable isotopes in the northern Chukchi Sea, western Arctic Ocean, over the past 200 years. Under permanent ice cover, organic carbon was dominated by land sources transported by sea ice and ocean currents, while local primary productivity was suppressed by light limitation. Since ice retreated in 20th century, organic carbon from primary production gradually overtook the terrestrial component.

Short summary
We present an open-access compilation of mineralogical and geochemical provenance data for surface sediments across the Arctic Ocean. The Circum-Arctic Sediment PROvenance Database (CASPROD) integrates four provenance proxies, including bulk sediment Sr–Nd isotopes, detrital zircon U–Pb ages, clay mineral assemblages, and detrital mineral compositions, from more than 4000 stations in the Arctic Ocean. All datasets are standardized with consistent metadata and are provided in multiple machine-readable formats.
We present an open-access compilation of mineralogical and geochemical provenance data for...
