High-resolution records of sulfur and insoluble particle concentrations from the B19 ice core in Greenland between 1530 and 1710 CE

We report high resolution (1 cm depth) sulfur concentrations from the B19 ice core in Greenland analyzed using inductively coupled plasma mass spectrometry (ICPMS) and mass concentrations of insoluble particles (5-10um size) using an inline Abakus® laser particle counter at the Desert Research Institute. Details about the analytical procedures are provided in the references. These records are used alongside ice-core crypto-tephra to characterize volcanic eruption sources in the 1660s CE.
