These data files contain the records of isotopes, anions, cations and organic compounds measured in the Bouvet Island ice core. The Bouvet ice core was collected as part of the Antarctic Circumnavigation Expedition (ACE) 2016-2017, and is the first ever ice core collected on the island. All analyses was carried out at the British Antarctic Survey, Cambridge, United Kingdom between 2016 and 2018. Analyses were carried out by analytical staff and a PhD student. Isotopes were measured using a Picarro instrument, anions and cations on a Dionex Intergrion Ion Chromatograph, and organics using High-Performance Liquid Chromotography Mass Spectrometry (HPLC-MS). Isotopes, anions and cations are measured as discreet 5cm core samples, while organics are measured at annual resolution core samples.

This data forms part of a suite of ice cores from the sub-Antarctic islands collected on the ACE cruise 2016-2017, for which anion, cation and isotope data will be made available separately.
