Latest Pleistocene and Holocene geomagnetic paleointensity on Hawaii
Mankinen EA and Champion DE. 1993. Latest Pleistocene and Holocene geomagnetic paleointensity on Hawaii. Science. 262(5132):412-416
Geomagnetic paleointensity determinations from radiocarbon-dated lava flows on the island of Hawaii provide an estimate of broad trends in paleointensity for Holocene time and offer a glimpse of intensity variations near the end of the last glacial period. When the data from Hawaii are compared with others worldwide, the intensity of the geomagnetic field seems to have been reduced from the Holocene average by about 35 percent between 45,000 and 10,00 years ago. A long-term reduction of this magnitude is compatible with reported increases in the production rate of cosmogenic nuclides during the same interval.
