Paper magnetograms

This database documents fluctuations in the Earth's regional (New Zealand) magnetic field measured before the age of digital records. New Zealand operates magnetic observatories in Canterbury (the Eyrewell Geomagnetic Observatory located at West Melton) and Scott Base in Antarctica, and supports the Apia observatory in Samoa. Observatories in the present days provide a record of temporal changes of the magnetic field, recording the three components of the magnetic field every second. Eyrewell (EYR), Scott Base (SBA) and Apia (API) geomagnetic observatories.
