Meteoric10Be_concentrations.xlsx

This data sheet contains new meteoric 10Be concentration data from marine sediment (biogenic muds) recovered during International Ocean Drilling Program Expedition 343 (JFAST) that help constrain the age, origin, and internal structure of the frontal prism at the Japan trench in the vicinity of the 2011 Tohoku-oki M9 earthquake rupture. Core data for IODO Expedition 343 can be fpound at http://sio7.jamstec.go.jp. Meteoric 10Be was extracted from sediment at the University of Vermont Cosmogenic laboratory in 2013. AMS measurements were made at the Scotish Universities Enviornmental Research Center (SUERC) in 2013. <br>
