Ocean conveyor and climate
The ocean overturning circulation has been compared to a conveyor belt that transports heat and salt, as well as carbon and other elements around the globe. The initial schematic of this global ocean circulation has been enriched with added loops and more sophisticated pathways. But the vertical exchange of water between surface and abyss in the northern North Atlantic and the high southern latitudes continues to be an important determinant of the vigour of the circulation. In this focus, we present a collection of research articles and opinion pieces that explore the interplay between ocean overturning in the north and south and climate change.
