Table 1 Depths (to the top of the layers), thicknesses, conductivities and 95 % confidence intervals of the recovered “joint” 1-D (layered) conductivity model. Note that 1-D model starts from the depth of 1 km; this is because the layered 1-D model is overlain by a thin (of 1 km thickness) shell of laterally variable conductance

From: Probing 3-D electrical conductivity of the mantle using 6 years of Swarm, CryoSat-2 and observatory magnetic data and exploiting matrix Q-responses approach
