Hartland Observatory is situated on the NW boundary
of Hartland village. The site is the southern half of a large
meadow, which slopes steeply northward into a wooded valley.
The sea (Bristol Channel) is about 3 km to both the north and
west of Hartland. BGS operates a three-component seismometer
set and a LF microphone at the observatory, and data from seismic
outstations are transmitted to the observatory by radio link.
The observatory was purpose-built for magnetic work, and
continuous operations began in 1957, the International Geophysical
Year (IGY). Hartland is the successor to Abinger and Greenwich
observatories. The moves from Greenwich to Abinger and then
to Hartland were made necessary as electrification of the
railways progressed, making accurate geomagnetic measurements
impossible in SE England. BGS took over control of Hartland
Observatory, from the Royal Greenwich Observatory, in 1968.
The observatory also houses an archive of material consisting
of records of geomagnetic measurements and observatory yearbooks
from all over the world.
There is one member of BGS staff stationed at Hartland.
