Summary: | Sulfate concentration and triple sulfur isotope (32S, 33S, 34S) data measured in TUNU2013 ice-core samples and calculated background-corrected isotope composition (Gabriel et al., in review). S-isotope analyses were made on 65 discrete samples (cross-sections of 6 cm2) cut from archived ice-core sections from TUNU2013, including prior background and full acid deposition lasting over 12 years. The sample resolution over the entire acid deposition event is 3 cm corresponding to a nominal 3-to-4-month age resolution. Sulfate concentration was measured by ion chromatography on the discrete samples, and the sulfate was purified from the melted ice using anion exchange columns. Triple sulfur isotopes (32S, 33S, and 34S) were measured on the samples using a Neptune Plus multi-collector inductively-coupled mass spectrometer (MC-ICP-MS) at the St Andrews Isotope Geochemistry Lab (STAiG lab) (Burke et al., 2019; Burke et al., 2023) and are reported as δ34S and D33S relative to Vienna-Canyon Diablo Troilite (V-CDT), ... |
