Sun Observations in South Georgia.

Geomagnetism is a science area within Earth Hazards and Systems, a programme of the British Geological Survey (BGS). BGS is a component body of the Natural Environment Research Council.

The Geomagnetism team measures, records, models and interprets variations in the Earth’s natural magnetic fields. Our data and expertise help to develop scientific understanding of change in the Earth and the environment, from deep within the core out into space. We also provide geomagnetic products and services to industry and to academic colleagues and we use our knowledge for information and education.
