A carbon sink shrinks in the Arctic

Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean's ability to absorb carbon dioxide from the atmosphere into the deep ocean and store it there.
