Fig. 3

Plots of apparent resistivity values (y-axis) against distance along transect (x-axis). The data for both panels are the same as Fig. 2. The black dotted lines indicate the spline fits for each of the replicates and the solid coloured lines represent the raw apparent resistivity values. As before, it appears that the lower altitude mean (bottom panel) has less variability around it than the higher altitude (top panel). For the spline model we can evaluate the repeatability by comparing SNRs (see Fig. 5). Note that the dots diverge from the coloured lines where data are missing
