The British Geological Survey (BGS) has operated magnetic observatories on AscensionIsland (ASC) and the Falkland Islands (PST) since 1992 and 1994 respectively. These two remote South Atlantic locations were selected to increase the global distribution of continuous, quality vector magnetic data. However, such locations give rise to many operational problems with a resulting impact on data quality. Unlike BGS observatories in the United Kingdom, the South Atlantic observatories are largely operated unmanned, which requires that the instruments, recording facilities and data communications are reliable and cost-effective. This poster describes the observatory sites, instrumentation and logistics of remote operation, contrasting the success of the two observatories over the preceding thirteen years, and concludes with a summary of the distribution and quality of the recorded data.
