Resolution No.23 (1963): Repeat station measurements during the IQSY in support of the WMS

The IUGG endorses the recommendation of the CIG-IQSY Committee: "It is recommended that one special feature of the IQSY contribution to the land and ocean survey of the WMS should be provision of magnetic survey measurements at repeat stations through their re- occupation during the IQSY or at least within the 5 year period prior to the ending of the IQSY" and urges

  1. the intensification of repeat station surveys during the IQSY, in accordance with previous IAGA technical recommendations for repeat station observations and
  2. the listing of the kinds of repeat stations and the values secured during previous re-occupations useful to the WMS.
