Below 1.5 mHz the superconducting gravimeters (SGs; Figure 1) are competitive with the best spring gravimeters and seismometers and can achieve the lowest noise level at frequencies lower than ∼1.0 mHz (Van Camp 1999; Rosat et al. 2003; Widmer-Schnidrig 2003; Park et al. 2005). SGs can therefore make a significant contribution to the illumination of long-wavelength density heterogeneities in the Earth's mantle (Widmer-Schnidrig 2003). For reasons of price and complexity, the number of SGs is small compared to the number of sensors deployed in the Global Seismic Network (GSN). However, the potential...
