“…Similarly, a short full reversal of 0.4-0.8 ka, superimposed on a background of low relative paleointensity that lasted 1.5-2 ka, is reported from cores from the Blake Ridge (Bourne et al, 2013), the Bermuda Rise (Kissel et al, 1999;Channell et al, 2012), Irminger Basin (Channell, 2006), northwest of Iceland, and the southern Indian Ocean (Laj et al, 2006). These paleomagnetic data are consistent with cosmogenic nuclide production rates from sediment and ice cores (e.g., Muscheler et al, 2005;Ménabréaz et al, 2011;Nilsson et al, 2011), and are supported by Bayesian inversion of geomagnetic field evolution during the Laschamp in North America (Leonhardt et al, 2009). Bayesian inversion also suggests that the timing and duration of the Laschamp may vary according to locality (Leonhardt et al, 2009).…”
