摘要：

The 2191 m long ice core recovered at Byrd Station Antarctica in 1968 (BS68) was measured continuously by an electrical conductivity method (ECM). The ECM curve inferes the acidity of seasonal ice layers and major peaks, which identify clearly intermediate and prominent past volcanic activity over the last 50,000 years. We here also present recent data for a suite of the most striking volcanic events that occurred around 17.5 ka +/- 0.5 BP. These events emitted enormous amounts of HCl and HF into the atmosphere.
