Fig. 4From: A new miniaturized magnetometer system for long-term distributed observation on the seafloorGeomagnetic transfer functions and squared coherences between the new and conventional magnetometer systems at site OBM1. Bx and By indicate north and east components of geomagnetic field, respectively. The error bars represent 95% confidence intervals. The same geomagnetic signal is recorded when the real and imaginary components are 1 and 0, respectivelyBack to article page
