About HeartMath California Station

The Global Coherence Initiative (GCI) station in Boulder Creek, California is operated by the HeartMath Institute — a research organization that has spent over 30 years studying the connection between human heart rhythms and Earth's magnetic fields. Their monitoring network places sensitive magnetometers at strategic locations around the globe.

The California station provides daily 24-hour spectrograms covering 0-50 Hz. As SunGeo's first North American data source, it dramatically improves coverage for users in the Western Hemisphere. Schumann Resonance events driven by thunderstorm activity over the Americas are detected here hours before they register at European stations.

HeartMath's research into "global coherence" — the idea that Earth's magnetic field influences human physiology — aligns closely with SunGeo's mission to make geomagnetic data accessible and meaningful for everyday wellness. Visit nocc.heartmath.org
