Fig. 1

Frequency versus amplitude of seafloor electric field (mV/km) induced by sea-surface geomagnetic fluctuations (with an amplitude of 1 nT). Solid and broken lines: electric field on the PAC and PHS models, respectively (Table 1). Thick and thin black lines: results from models with a seawater layer whose thickness are 1000 and 4000 m, respectively. Gray lines: results from models without seawater layers. Chain line: at frequency of 0.01 and 0.001 Hz
