Abstract:
It has been predicted that the Arctic Ocean will sequester much greater amounts of carbon dioxide (CO 2 ) from the atmosphere as a result of sea ice melt and increasing primary productivity. However, this prediction was made on the basis of observations from either highly productive ocean margins or ice-covered basins before the recent major ice retreat. We report here a high-resolution survey of sea-surface CO 2 concentration across the Canada Basin, showing a great increase relative to earlier observations. Rapid CO 2 invasion from the atmosphere and low biological CO 2 drawdown are the main causes for the higher CO 2 , which also acts as a barrier to further CO 2 invasion. Contrary to the current view, we predict that the Arctic Ocean basin will not become a large atmospheric CO 2 sink under ice-free conditions.
