Geomagnetic micropulsations with periods 0.3-3 seconds ...
The classification and possible origin of geomagnetic micropulsations are discussed. In particular, pearls are described in some detail and previous investigations reviewed. Records from Victoria and Resolute Bay, Canada; Uppsala, Sweden; Reykjavik, Iceland; Huancayo, Peru; Ruth, Nevada and Isabella...
