Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.Abstract Understanding the ventilation of the deep ocean, where most ocean carbon is stored, is essential to understanding how changes to ocean carbon budgets contribute to climate change. In the Arctic Ocean, shifts in ice cover, stratification and temperature are likely to impact carbon sequestration in the ocean interior.
