Fig. 3

Oceanic M2 tide induced magnetic field amplitudes in dependence of analyzed time series length at all three analysed coastal magnetometer stations. The amplitudes were obtained after phasing and averaging the data with the mean (left) and the median (right). Solid lines show the results for the analysis conducted on the first n years of the 10 year time series (corresponding to lower x-axis), while the dotted lines show the analysis results for the last n years of data (corresponding to upper x-axis)
