The technical details of a balloon stratospheric mission that is aimed at measuring the Schumann resonances are described. The gondola is designed specifically for the measuring of faint effects of ELF (Extremely Low Frequency electromagnetic waves) phenomena. The prototype met the design requirements. The ELF measuring system worked properly for entire mission; however, the level of signal amplification that was chosen taking into account ground-level measurements was too high. Movement of the gondola in the Earth magnetic field induced the signal in the antenna that saturated the measuring system. This effect will be taken into account in the planning of future missions. A large telemetry dataset was gathered during the experiment and is currently under processing. The payload consists also of biological material as well as electronic equipment that was tested under extreme conditions.

W artykule opisano szczegóły techniczne misji balonowej, mającej na celu pomiar rezonansów Schumanna. Gondola została zaprojektowana do pomiaru słabych efektów ELF (fale elektromagnetyczne o skrajnie niskiej częstotliwości). Prototyp spełnił założenia projektowe. Układ do pomiaru ELF działał poprawnie przez całą misję, jednak poziom wzmocnienia sygnału, który był dobrany zgodnie z pomiarami naziemnymi, okazał się za duży. Ruch gondoli w ziemskim polu magnetycznym indukował w antenie sygnał, który wprowadzał układ pomiarowy w stan nasycenia. Ten efekt zostanie wzięty pod uwagę w planowaniu przyszłych misji. Podczas eksperymentu zebrano duży zestaw danych telemetrycznych, który jest obecnie analizowany. Ładunek zwierał również materiał biologiczny oraz sprzęt elektroniczny, który był testowany w warunkach ekstremalnych.

Schumann Resonance Frequencies Found within Quantitative Electroencephalographic Activity: Implications for Earth-Brain Interactions

Recent measurements of cerebral quantitative electroencephalographic power densities within the first three harmonics of the earth-ionosphere Schumann resonances and the same order of magnitude for both systems electric and magnetic (pT) fields suggest the possibility of direct intercalation or interaction. The phase modulations of the Schumann propagations and those associated with consciousness are very similar. Quantitative solutions from contemporary values for the physical parameters of the human brain and the earth-ionospheric resonances suggest that electromagnetic information maintained during the first 30 min of experience could be also represented within a property of the (Hilbert) space occupied by the ionospheric wave guide within the earth’s magnetic field. Several astronomical phenomena, including gravitational waves and the neutral hydrogen line, display physical properties with magnitudes matching cerebral electromagnetic activity particularly during light sleep. The presence of Schumann frequencies within the human brain may have greater significance than hereto assumed for the human species.

Variations in the global atmospheric electric circuit are investigated using a wide range of globally spaced instruments observing VLF (~10 kHz) waves, ELF (~300 Hz) waves, Schumann resonances (4-60 Hz), and the atmospheric fair weather electric field. For the ELF/VLF observations, propagation effects are accounted for in a novel approach using established monthly averages of lightning location provided by the Lightning Image Sensor (LIS) and applying known frequency specific attenuation parameters for daytime/nighttime ELF/VLF propagation. Schumann resonances are analyzed using decomposition into propagating and standing waves in the Earth-ionosphere waveguide. Derived lightning activity is compared to existing global lightning detection networks and fair weather field observations. The results suggest that characteristics of lightning discharges vary by region and may have diverse effects upon the ionospheric potential.
