Analysis of the natural electric field at different sea depths

The natural electric field at the depth of 0 ∼ 1500 m in high seas South China Sea is obtained by using a new type measuring device. data 0.01 0.5 Hz and 30 frequency range are analyzed respectively. results show that induced generated surface wave (about 0.14 experiment) obvious 50 but can be ignored greater than 100 m. When increases from to m, peak-to-peak value gradually decreases. At 1000 values 0.04 0.08 μV/m range, 0.07 0.1 range. last, coastal water near Sanya City, where 15 measured means sinking about 2 4 By comparing with water, we find latter has larger nearly same depth. In addition, line spectrum noise often occurs while it rarely observed when more
