On the long-range offshore transport of organic carbon from the Canary Upwelling System to the open North Atlantic ...

A compilation of measurements of net community production (NCP) in the upper waters of the eastern subtropical North Atlantic had suggested net heterotrophic conditions, purportedly supported by the lateral export of organic carbon from the adjacent, highly productive Canary Upwelling System (CanUS)...
