Geomagnetism and palaeomagnetism. Proceedings.
Abstract
The aim of the Institute was to improve the interaction between workers in observational geomagnetism (using historical data) and archaeo- and palaeo-magnetism (using the remanent magnetization of man-made artefacts and of natural sediments and rocks) and those trying to interpret the data in terms of mechanisms inside or outside the Earth, particularly those developing dynamo theories of the field. The material discussed ranged from magnetic bacteria swimming round a circle in a few seconds, the effect of El Niño, through secular variation with time scales of tens to thousands of years and the mechanics of individual field reversals and excursions to possible modulation of average reversal frequency on the hundred million year time scale.
