New Zealand Geomagnetic Database

Access here. This database documents the short-term and long-term fluctuations in the Earth's regional (New Zealand) magnetic field, including induction and diurnal effects.

The database consists of three interrelated components: observatory records, three- component repeat station observations, and three-component single observations.

New Zealand operates magnetic observatories at Eyrewell in Canterbury and Scott Base in Antarctica, and supports the Apia observatory in Samoa. Observatories provide a record of temporal changes of the magnetic field, recording the three components of the magnetic field every second.

Three-component repeat station observations are made at a number of sites in New Zealand at three-yearly intervals and at sites on Subantarctic and South Pacific islands as the opportunity arises.
