Latest Spectrogram
Hey there! This past week at our California station has been pretty mellow. We saw a nice peak activity of 55, but overall things stayed on the quieter side, with no major spikes above 80 to report. It's been a pretty calm and steady week for the Schumann Resonance here!

Open calendarGCI001 — heart of the global coherence network
GCI001 is part of HeartMath Institute's Global Coherence Initiative (Boulder Creek, California), a network designed to monitor how geomagnetic activity correlates with human physiology and collective coherence.
Unlike traditional academic stations, GCI sites are tuned for wellness research — exploring how magnetic field fluctuations affect sleep, mood, and heart rate variability.
Its daily spectrograms capture both Schumann resonance harmonics and ultra-low-frequency (ULF) activity, giving a holistic picture of the local electromagnetic environment. Visit nocc.heartmath.org

Frequently asked questions
How does GCI001 measure Schumann resonance?
GCI001 uses a magnetometer tuned for ULF/ELF frequencies (0–50 Hz). It produces a daily 24-hour spectrogram showing Schumann harmonics alongside ultra-low-frequency activity relevant to wellness research.
Why is GCI001 important to our network?
GCI001 is part of HeartMath Institute's Global Coherence Initiative, a network specifically designed to study how geomagnetic activity correlates with human physiology. It brings a wellness-research perspective absent from purely academic stations.
When was its last major event?
Check the Notable events section above — it lists the top 10 highest-score events at GCI001 from the last 30 days, each linked to the full daily report.
How reliable is the data?
GCI001 is operated by the HeartMath Institute, a nonprofit research organization studying the interconnection between human physiology and Earth's magnetic field. The Global Coherence Initiative has been running since 2008 and publishes peer-reviewed research.
Where does the raw data come from?
Raw daily spectrograms come from nocc.heartmath.org. We fetch the latest plot once per day after publication. Visit heartmath.org/gci for the full Global Coherence Initiative program and research.
