Canadian Magnetic Observatories
Magnetic observatories are permanent measuring stations that monitor the geomagnetic field to very high accuracy over time scales ranging from seconds to decades and beyond. They require environments that remain stable over many years and that are free from significant cultural (magnetic) interference. In technical terminology, a magnetic observatory determines the geomagnetic field in absolute terms; that is, the measurements can be calibrated back to fundamental standards. In Canada, the magnetic observatories are operated by the Geological Survey of Canada. Currently, 14 Canadian observatories are in operation. Despite the ideal of long term stable environments, occasionally observatories must be closed or re-located. The current magnetic observatories use the CANMOS instrumentation.
