Increased productivity in the subantarctic ocean during Heinrich events

Article Abstract:

A combination of molecular fingerprints of algal productivity and radioisotope tracers of sedimentation is used to document eight periods of increased productivity in the subpolar Southern Ocean during the past 70,000 years that occurred within 1,000-2,000 years of a Northern Hemisphere Heinrich event. Possible causes for such a link, including increased supply of iron from upwelling and increased satisfaction during the growing season, which implies an alteration of the global ocean circulation during Heinrich events, is discussed.
