Time series of the axial dipole moment reconstructions spanning the past 9000 years (panel A)), with a zoom for the last 3200 years (panel B)). The black solid line depicts GMAG.9k (the reconstruction presented and used in this work) with ± 1σ and the full range variability presented by the gray shading and the hatching, respectively. Other reconstructions shown are (Licht et al. 2013) denoted as AF_M, (Genevey et al. 2008) denoted as G08, (Nilsson et al. 2014) denoted as pfm9k.1b and pfm9k.1a, (Knudsen et al. 2008) denoted as Kn08, and (Pavón-Carrasco et al. 2014) denoted as SHA-DIF.14k. For better readability, error bars were omitted for these curves, but this does not affect the discussion of the results (see text).
