  • 2022 Definitive 1-minute Scott Base (SBA) data is continuous 1-second data recorded by New Zealand's Geomagnetic Observatories SBA in 2022 that was processed at 1-minute sampling, cleaned (spikes removed) and baseline (absolute values) corrected following INTERMAGNET guidelines. The data was submitted to INTERMAGNET in May 2023 and passed the INTERMAGNET reviewing process. DOI https://doi.org/10.21420/axhk-e303 Cite as: Thornton, M., Goodyear, G., Shaw, S.

  • The dataset is composed of the original sheets on which the fields were recorded by light on photographic paper. Each sheet holds 24 hours of three recorded magnetic field components. Most of the components were labelled XYZ; some were labelled DHZ (e.g. 1991 magnetograms), and others were not labelled at all (e.g. 1966 magnetograms).

  • Preliminary 1-second and 1-minute Scott Base (SBA) data are submitted to INTERMAGNET in a standardized file format (IAGA-2002) every hour. The data can be downloaded via a free web access provided by INTERMAGNET at http://www.intermagnet.org/data-donnee/download-eng.php (Data Type: ‘provisional’). 1-minute (Sample Rate: ‘minute’) ‘provisional’ SBA data are available since 1996. 1-second data (Sample Rate: ‘second’) ‘provisional’ SBA data are available since 2012.

  • The dataset is composed of the original sheets on which the fields were recorded by light on photographic paper. Each magnetogram sheet holds a record of 24 hours. Normally the magnetic field components H and D are recorded; some years in addition do have recordings of the Z component. Apia (API) 1907 – 1913 Apia (API) 1932 – 1955 There are magnetograms for 1956 - 1994, but they are not complete and the contents need yet to be specified. For 1907 - 1913, magnetograms for H and D are mostly complete. The years 1908 - 1911 have some additional magnetograms that might be for the Z component. GNS Science does not hold records from 1914 to 1931. After the long gap, there are fewer magnetograms for 1932 - 1936; from 1937 - 1955, each year has magnetograms for H, D & Z for most days. There are Apia rapid runs available for 1956 - 1978, and 1983-1986, and Apia Wider Range (WR) from 1977, 1979, 1980, 1983, 1985, 1986. Some of the records were received from the University of Göttingen, Germany, who originally established this magnetic station. DOI: https://doi.org/10.21420/WYV2-6K33 Cite as: GNS Science. (2022).

  • 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.
