Ice core chemistry, conductivity, and stable nitrate isotopic composition of the Samalas eruption in 1259 from the ISOL-ICE ice core, Dronning Maud Land, Antarctica
GB/NERC/BAS/PDC/01199

Summary

Abstract:
This dataset contains a subset of the ice core data for the ISOL-ICE core recovered from Dronning Maud Land, Antarctica in January 2017 (https://doi.org/10.5285/9c972cfb-0ffa-4144-a943-da6eb82431d2). The subset reported here contains ice core data from the 1455 - 1227 AD period (60.80 - 79.45 m depth) and covers the volcanic eruption of Samalas, Indonesia in 1259. The ice core was dated by annual layer counting and identifying volcanic horizons as fixed time markers. Here we report i) the age-depth model over the 1455 - 1227 AD period, ii) high-resolution nitrate stable isotopic composition of discrete ice core samples, and iii) nitrate, sodium and magnesium mass concentrations and electrolytic meltwater conductivity from continuous flow analysis (CFA).

Funding was provided by the NERC grant NE/N011813/1.
