Hurst, A.W.; Bennie, S.L. 2014 Repeat magnetic measurements in Antarctica, January 2012. Lower Hutt, N.Z.: GNS Science. GNS Science report 2014/08 29 p. https://doi.org/10.21420/efes-8v37
Abstract: These measurements were part of the GNS Science programme of repeat magnetic measurements, to monitor the slow changes in the magnetic field of the earth in the New Zealand region. Measurements were made at Cape Evans and at Lake Vanda. The measurements at the former site were referenced to the Scott Base magnetic record, to calculate the 2012 magnetic field at Cape Evans. At Lake Vanda, the magnetic field was recorded for nearly four days. This record was used in the total field analysis, but for declination and inclination direct differences from the Scott Base records were more reliable. All the magnetic values were then adjusted to provide a 12-month average, centred on 1 January 2012, using the deviation of the Scott Base record at the time of measurement from the 12-month average. The previous Astro A magnetic site has now been drowned by a rising Lake Vanda, so as well as recording at Vanda Weir, a backup site, Vanda Granite, was established and measured. (auth)
