Short summary
Short summary
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.

We use regional 2D seismic to reconstruct the late Miocene to Pleistocene ice sheet history of the Northeast Greenland continental shelf. Regional borehole correlations show that the first ice stream advance across the shelf occurred around 6.4 Ma. Subsequently, a marked change in ice sheet configuration towards intensified cross-shelf ice streaming post-dates 4.1 Ma, possibly correlating to the intensification of the Northern Hemisphere glaciations.

Short summary
Marine geologic data from NE Greenland provide new information about the behavior of the Greenland Ice Sheet from the last glacial period to present. Seafloor landforms suggest that a large, fast-flowing ice stream moved south through southern Dove Bugt. This region is believed to have been deglaciated from at least 11.4 ka cal BP. Ice in an adjacent fjord, Bessel Fjord, may have retreated to its modern position by 7.1 ka cal BP, and the ice halted or readvanced multiple times upon deglaciation.

Short summary
Short summary
Terrestrial sources of nitrate are important contributors to the nutrient pool in the fjords of Kongsfjorden and Rijpfjorden in Svalbard during the summer, and they sustain most of the fjord primary productivity. Ongoing tidewater glacier retreat is postulated to favour light limitation and less dynamic circulation in fjords. This is suggested to encourage the export of nutrients to the middle and outer part of the fjord system, which may enhance primary production within and in offshore areas.

Short summary
We present marine geoscientific data from Store Koldewey Trough, one of the largest glacial troughs offshore NE Greenland, to reconstruct the ice drainage pathways, ice sheet extent and ice stream dynamics of this sector during the last glacial and deglaciation. The complex landform assemblage in the trough reflects a dynamic retreat with several periods of stabilization and readvances, interrupting the deglaciation. Estimates indicate that the ice front locally retreated between 80–400 m/year.
