Measurements of elf noise on land and under the ocean to depths of 1000 feet were made in a joint NEL-USL program. Spectral analysis of recorded data is presented. Underwater measurements revealed significant peaks in the region of the first resonant frequency of the earth-ionosphere cavity between 7 and 10 cs. Author
