AB: Field measurements were made to test the feasibility of using HAARP stimulated ionospheric emissions of Very Low Frequency (VLF) electromagnetic signals, as probe waves for geophysical studies. The test site chosen for the experiment was a mud volcano near Tolsona, Alaska on the Glenn Highway. Data acquisition was done with a Zonge GDP-32 Receiver, magnetic coils, and electric lines provided by UAF. HAARP was run at full power and modulated at varying frequencies in the VLF range at frequencies of: 1, 4, 8, 16, 32, 96, 4096 and 6144 Hz. Both natural and induced VLF signals were recorded, with the intention of seeing a stronger signal at HAARP-generated frequencies upon examination of the data. Initial analysis indicates HAARP- generated VLF signals have the signal strength necessary for use as probe waves in geophysical field studies. However it is also clear that power lines near the site had minor interference with the data and therefore further analysis is needed before any direct claims can be made. This experiment was part of and made possible by the PARS 2007 Summer School.
