Measurements for 10Be were performed at the accelerator mass spectrometry facility ASTER (Aix-en-Provence, France) after preparation of targets at the Cosmogenic Laboratory of ISTerre (Grenoble, France). Calibration against NIST Standard Reference Material 4325 with an assigned 10Be/9Be ratio of 2.79 10-11 and a 10Be half-life of 1.387 ± 0.012 106 years (Chmeleff et al., 2010, doi:10.1016/j.nimb.2009.09.012; Korschinek et al., 2010, doi:10.1016/j.nimb.2009.09.020). 10Be concentration uncertainties include analytical uncertainties from the counting statistics, instrumental variability (1%) and chemical blank, whereas the age uncertainties also include the errors of the production rate introduced by the scaling model of Lal (1991) and Stone (2000, doi:10.1029/2000JB900181), and geomorphic scaling factors of Dunne et al. (1999, doi:10.1016/S0169-555X(98)00086-5).
