Burial of organic material in marine sediments represents a dominant natural mechanism of
long-term carbon sequestration globally, but critical aspects of this carbon sink remain …

As a contribution to the Regional Carbon Cycle Assessment and Processes phase 2
(RECCAP2) project, we present synthesized estimates of Arctic Ocean sea‐air CO2 fluxes …

Arctic marine ecosystems are undergoing rapid correction in response to multiple
expressions of climate change, but the consequences of altered biodiversity for the …

Abstract Changes in the inflow of Atlantic Water (AW) and its properties to the Arctic Ocean
bring more warm water, contribute to sea ice decline, promote borealisation of marine …

The protection of organic carbon through association with iron minerals (Fe R) is an
important factor in its stabilisation, long-term storage, and burial efficiency in marine …

Constraining the mechanisms controlling organic matter (OM) reactivity and, thus,
degradation, preservation, and burial in marine sediments across spatial and temporal …

Subsea permafrost carbon pools below the Arctic shelf seas are a major unknown in the
global carbon cycle. We combine a numerical model of sedimentation and permafrost …

On Arctic shelves, where primary production occurs in both the pelagic and sympagic (ice-
associated) habitats, sympagic organic material (OM) can constitute a disproportionate …

Climate change is altering nutrient cycling within the Arctic Ocean, having knock-on effects
to Arctic ecosystems. Primary production in the Arctic is principally nitrogen-limited …

Over recent decades the highest rates of water column warming and sea ice loss across the
Arctic Ocean have been observed in the Barents Sea. These physical changes have …
