Changes in non-dipolar field structure over the Plio-Pleistocene: New paleointensity results from Hawai`i compared to global datasets

Abstract

Global compilations of paleointensity do not conform with the hypothesis that Earth's time-averaged magnetic field is a dipole (GAD field)• We present 31 new paleointensity results from 0-4 Ma from the Hawaiian Islands• Results for 0-1.5 Ma are inconsistent with a GAD field when compared to global datasets reanalyzed the same way, but are consistent for 1.5 to 2.
