Fig. 7From: On the modelling of M2 tidal magnetic signatures: effects of physical approximations and numerical resolutionEffect of variable seawater conductivity and sediments. Differences between the 3-D and 2-D solutions calculated at the Earth’s surface with the elmgFD code at \(j_{\mathrm{max}}=480\). The 3-D solution includes temperature and salinity-dependent seawater conductivity and variable sediment thickness and discretizes the ocean with 102 layersBack to article page
