Resolution No.26 (1967): Repeat magnetic observation in Antarctic

The IAGA noting with satisfaction the increased number of magnetic determinations in the Antarctic since the IGY but further noting that the number of magnetic stations now existing in the Antarctic cannot provide sufficient data for reducing these determinations to common epochs to be used for preparing Antarctic and world magnetic charts in the future, recommends that a network of regular repeat magnetic stations be organised in the Antarctic at a number of especially chosen places where the magnetic field has only small anomalies. The observations at the repeat stations should be repeated each five years. IAGA requests the help of SCAR in organising the repeat stations.
