Scientists discover a new pathway for the movement of carbon-rich materials from productive Arctic coastal waters to the deep ocean. Every year, the transfer of carbon-rich particles across the shelf in the Barents and Kara Seas could trap as much as 3.6 million metric tons of CO2 in the deep Arcti

and other institutions, this previously unknown transport route uses the biological carbon pump and ocean currents to absorb atmospheric CO2 on a scale equivalent to Iceland’s total annual emissions. They recently published their findings in the journalThe central Arctic Ocean has limited biological productivity when compared to other oceans. This is due to the limited sunlight caused by the Polar Night or sea-ice cover, as well as the scarcity of available nutrient sources.
“Based on our measurements, we calculated that through this water-mass transport, more than 2,000 metric tons of carbon flow into the Arctic deep sea per day, the equivalent of 8,500 metric tons of atmospheric CO2. Extrapolated to the total annual amount revealed even 13.6 million metric tons of CO2, which is on the same scale as Iceland’s total annual emissions,” explains Dr.
