“…The raw data to create these maps are available from (Laverick et al, 2022) F I G U R E 7 Organic matter content. Organic matter content for our mapped domain was predicted using our estimates of % sediment composition as silt by weight, and the relationship derived from (Pathirana et al, 2014). The raw data to create the map are available from (Laverick et al, 2022) discrete habitat classes by NGU-SEVMORGEO and translated these into pseudo-continuous sediment variables (rock, gravel, sand, silt, Figure 5).…”

The Arctic is one of the most rapidly changing environments on the planet. Climate data show that the poles are warming at a faster rate than the global average (Clem, 2020;Holland & Bitz, 2003;Koenigk et al., 2020), which could result in a seasonally ice-free Arctic by the middle of the 21st century (Thackeray & Hall, 2019). Not only does temperature affect sea ice concentrations, but also biochemical processes in the ocean (Gruber, 2011) and the

Abstract. There is generally a lack of knowledge on how marine organic carbon accumulation is linked to vertical export and primary productivity patterns in the Arctic Ocean. Despite the fact that annual primary production in the Arctic has increased as a consequence of shrinking sea ice, its effect on flux, preservation, and accumulation of organic carbon is still not well understood. In this study, a multi-proxy geochemical and organic-sedimentological approach is coupled with organic facies modelling, focusing on regional calculations of carbon cycling and carbon burial on the western Barents Shelf between northern Scandinavia and Svalbard. OF-Mod 3-D, an organic facies modelling software tool, is used to reconstruct and quantify the marine and terrestrial organic carbon fractions and to make inferences about marine primary productivity changes across the marginal ice zone (MIZ). By calibrating the model against an extensive set of sediment surface samples, we improve the Holocene organic carbon budget for ice-free and seasonally ice-covered areas in the western Barents Sea. The results show that higher organic carbon accumulation rates in the MIZ are best explained by enhanced surface water productivity compared to ice-free regions, implying that shrinking sea ice may reveal a significant effect on the overall organic carbon storage capacity of the western Barents Sea shelf.
