SP19 Gas Chronology

We present the SP19 gas chronology for the South Pole ice core. The chronology is based on stratigraphic matching of abrupt methane (CH4) changes. To construct the chronology, abrupt changes in CH4 during the glacial period and small, 20-30ppb, centennial scale changes in CH4 were used with analogou...
