This new evidence is consistent with the factor-of-2 equator-to-pole paleointensity signature of a geocentric axial dipole field and also indicates that the time-averaged field is considerably weaker than the present-day field. The resulting dipole moment provides a new calibration standard for cosmogenic isotope production rates and suggests that the present decrease in geomagnetic field intensity may simply be a return to a more average magnitude rather than a harbinger of a polarity reversal.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383951795412570881","@type":"Researcher","foaf:name":[{"@value":"Huapei Wang"}],"jpcoar:affiliationName":[{"@value":"Earth and Planetary Sciences, Rutgers University, Piscataway, NJ 08854;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383951795412570880","@type":"Researcher","foaf:name":[{"@value":"Dennis V.
