Geomagnetism Magnetic Observatories Map
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,
13 Canadian observatories are in operation. Despite the ideal of long
term stable environments, occasionally observatories must be closed
or re-located. Twelve of the current observatories use the CANMOS
instrumentation, while Alert uses an earlier AMOS III system.
