Raw trace element data obtained by LA-ICP-MS for analysed tephra across 751-763 CE from B19 and TUNU2013 ice cores (Greenland)

Raw Trace element data of analysed ice core samples from B19 [78.00°N/36.40°W] and TUNU2013 [78.04°N/33.88°W] ice cores (Greenland) across the period 751-763 CE. Trace element data was obtained by LA-ICP-MS at the University of St Andrews, UK using a beam diameter of 20µm, laser energy of 3.5 J cm-2 (4 Hz repetition rate), 30-s ablation time and 20-s background measurement.
