Abstract:

The Foraminifera populations and distributions of five deep sea sediment cores recovered from the Arctic Ocean yielded data on 126 species of Foraminifera. Abundance data and species appearance and mortality data across geomagnetic reversal intervals in the cores show no positive correlation. Arctic Ocean Foraminifera apparently do not respond in any significant way to magnetic reversals of the earths magnetic field. Modified author abstract
