Wavelet analysis of geomagnetic jerks
2014Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more singular than previously supposed; their """"regularity"""" is closer to 1.5 than to 2.

Geomagnetic jerks seen in historical declination at Munich
2009Long series of geomagnetic field change are crucial for understanding the geodynamo process. The longest historical series come from magnetic declination, which can be obtained from several sources. Apart from early measurements made on ships for navigational purposes, declination information has e.g.
