Naturally-occurring emissions in the ELF- and VLF-band were studied in Northern Scandinavia from June 1964 to August 1966. Both of physical and practical reasons this investigation has been divided into four subgroups, namely 1 Measurements of different types of hydromagnetic emissions between DC and 6 cps. 2 Studies of the earth-ionosphere cavity resonance band in the frequency range 6 to 100 cps. 3 Investigation of the fine structure of the emission band centered at approximately 700 cps, as well as recordings of the natural electromagnetic spectrum between 1 and 10 kcs. 4 Studies of the enhanced VLF- and LF-emissions at six discreate frequencies between 2.3 and 50 kcs. The results are presented and discussed. Author
