Abstract
Our recently published results from Pleistocene sediments in northwestern Canada provided no compelling evidence for the so-called Blake Event but did yield an interesting secular variation pattern interpreted as the signature of one or more stationary sources near the core-mantle boundary. New data, from a site about 1 km away, confirm this interpretation and thus support the division of the non-dipole field into drifting and standing parts in the geological as well as the bistoric past. Measurements of the initial susceptibility of all 694 samples in this study and the previous one greatly facilitated stratigraphic correlation between the four 6 m sections involved.
