Scientists discovered carbon conveyor phenomenon in Arctic seas

The Barents and Kara seas annually absorb an amount of CO2 comparable to Iceland's annual greenhouse gas emissions.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Russian scientists from the Arctic and Antarctic Research Institute, together with German scientists, found that the Kara and Barents seas absorb over 13.6 million tons of CO2 (carbon dioxide) every year.

The “carbon conveyor” transports from the air to the depths of the ocean a volume of greenhouse gases comparable to Iceland’s annual emissions, TASS reports citing the German Alfred Wegener Institute.

The study was carried out on the Akademik Treshnikov ship’s board in 2018 off the northern coast of Russia. Scientists followed the movement of the flow of water, which sinks to the bottom of the Arctic ocean in the Barents sea and follows the direction of Severnaya Zemlya and the Laptev sea. Calculations showed that water carries a huge mass of organic matter. The researchers note that this phenomenon should be taken into account when assessing the carbon budget of the Arctic.

Previously, scientists measured the rate of sea ice melt in the Arctic. Methane deposits in the Arctic begin to thaw. We also reported that Nornickel presented three scenarios for the development of the global economy and climate change.
