Mejia, V., Opdyke, N.D. and Perfit, M.R. (1996). Paleomagnetic field intensity recorded in submarine basaltic glass from the East Pacific Rise, the last 69 KA. Geophysical Research Letters 23(5): 475-478. doi: 10.1029/96GL00018.

Paleointensity determinations were obtained from basaltic glass recovered from the northern East Pacific Rise using the Thelliers' (1959) method as applied by Pick and Tauxe The samples are up to (a)69 Ka old based on their ridge axis and U-series disequilibria results show a general increase in paleointensity of the field from 69 Ka to the present with values ranging from 50% higher than the present field to as low as 26% The average dipole moment is 8.32 x 10(22) Am-2 which is similar to the present moment. The results are in general agreement absolute and relative paleointensity records.
