Abstract

We agree with the comments of Camfield and Gough in that it is desirable to remind the magnetospheric community that geomagnetic anomalies can affect the interpretation of data from certain ground stations. However; of the three stations in question, those at Alert and Mould Bay, N.W.T., are regular magnetic observatories operated by the Canadian Department of Energy, Mines, and Resources for many years, and they were not chosen by the IMS planners. Unlike the previous international programs such as IGY and IQSY, the essence of the IMS lies in the active coordination of the existing multidisciplinary programs with a minimum of increment funding. Thus the inclusion of the Alert and Mould Bay observatories in the IMS network [Lanzerotti et al., 1976] came about quite naturally. Indeed, with the limited increment funds available to the Canadian and U.S. IMS programs it would be virtually impossible to relocate the Alert and Mould Bay observatories or to add replacement stations. To do so would have meant sacrificing other strategically located magnetometer stations designed for specific purposes.
