The results suggest that through this carbon sink current, the Barents Sea could remove about 30 per cent more carbon dioxide from the atmosphere than previously thought.
Anya Waite, scientific director at the Ocean Frontier Institute and a professor in Dalhousie University's Department of Oceanography, was part of an Arctic expedition that has led to the discovery of a marine current that acts as a conveyor belt to move carbon into the deep ocean. - Dalhousie UniversityHALIFAX, N.S. — New research is shedding light on an underwater Arctic current that moves massive amounts of carbon into the deep sea.
“It's under ice, it's hard to get there, this particular part of the continental shelf is Russian, so it's . . . just for geopolitical reasons very hard to reach.” “It doesn't sound very big, but for ocean plankton, that's quite big and it means that they sink. So, when you're looking for a carbon sink, you want particles in the ocean that are literally going to sink down to the sea floor.”
“And every time he crossed through that current, there was this rich concentration of particles in the current.” “This is part of the carbon sink of Canada, if you will, that's carried out through the Russian shelf and then into the deep Arctic,” she said. “Getting to net-zero, we're going way too slowly. And we can't do everything that needs to be done, so we have to get to net-negative, and that means understanding the big carbon sinks in the world because if they change, then net-negative means something completely different.
