Studies of geomagnetic polarity reversals have generated some of the biggest and most interesting debates in the paleomagnetic and wider solid Earth geophysics communities over the last 25 years.

The Subject

§ 1. The present research forms part of a wider investigation of terrestrial magnetism, the main object of which is the study of certain electrical phenomena that are associated with solar emissions absorbed in the upper atmosphere, and with the systematic motions of the upper atmosphere. The subject also bears on the electrical conductivity of the solid earth and oceans. The results are briefly discussed from this standpoint in Part IV. The immediate subject of the paper is the lunar diurnal variation of the earth’s magnetic field, and particularly that of the declination at Greenwich, although the results of extensive reductions for other elements, at Batavia, Zikawei, and Pavlovsk, are also included.

Effective Angle

Results of a study at Brisbane of individual night-time sferics of known origin are described. A propagation attenuation minimum was observed in the 3-6 kHz range. The geographic distribution of sferic types was also examined. Apparent propagation asynunetries were observed, since sferics were detected at greater ranges to the west than to the east at 10 kHz, whilst the number of tweek-sferics arising from the east was about four times that arising from the west. Comparison with European studies suggest that these asymmetries are general. These results are then " interpreted in terms of an ionospheric reflection cgefficient which is a function of the effective angle of incidence of the wave on the ionosphere and of orientation with respect to the Earth's magnetic field within the ionosphere.
