Sample preparation and laboratory measurement values for in-situ meteoric Beryllium 10 concentrations before and after Hurricane Maria in Dominica and the percent difference between the two time periods

Comments: 1) July 2017 refers to samples collected before Hurricane Maria and January 2018 refers to samples collected after Hurricane Maria. 2) 2017 samples were measured at Lawrence Livermore National Laboratory and 2018 samples were measured at Purdue Rare Isotope Measurement (PRIME) Laboratory. Ratios from both laboratories were normalized against standard 07KNSTD3110 with an assumed ratio of 2.85 x 10^v12 (Nishiizumi et al., 2007). […]
