A sma device cooried intil a field near Steenhive, Aiberdeenshire, hauds track o a naitural hum in the atmosphere cryed Yird’s “hertbeat.” This steady law-frequency wave, kent as Schumann Resonance, is gien oot by lichtnin flashes aroond the warld. Aroond 50 times ilka second, lichtnin sends oot wee energy waves that boonce atween the grun an the lift’s ionosphere.

The University o Aiberdeen pit the sensor in a quaet spot, awa fae city lichts an signals that cuid distort its readins. Inside a simple plastic kist, miles o cable connect tae heich-resolution detectors. Thae detectors pick up tiny electromagnetic signals, whit the computer taks tent o. This set-up is ane o juist twa in the UK. The ither is in Eskdalemuir in the Scottish borders.

Scientists study thae waves for tae fin oot mair aboot Yird’s wather, climate chynge, an even solar storms—muckle brusts o energy fae the sun. Fan solar storms hit, they set aff Alfvén waves, whit the team plans tae observe. Located at a heicher latitude, Aiberdeenshire is pairticularly suited for this resairch.

Resairchers howp comparin data fae baith UK sensors will shed licht on hoo thae law-frequency waves relate tae seismic events like yird-quakes. Some believe that Schumann Resonance micht influence human brain activity, as its main frequency owerlaps wi brain wave ranges tied tae relaxation an sleep.

Fyle simple tae look at, the device’s purpose is complex. Lichtnin creates electromagnetic signals sae faint that anely specialised gear can detect an record them. Thae measurements cuid appen new windaes intae unnerstaundin Yird’s naitural rhythms an their link tae wir halth an environment.
