Abstract
Since the major ion components (F-, Na+, Cl-, SO42-, Ca2+, etc.) of ice sheets of Antarctica originate mainly from atmospheric fine dust and gas, their composition and concentration change characteristics restore the past atmospheric environment changes. Recovered fluoride ion (F-) recordings in polar regions are known as representative proxies that point to past large-scale volcanic activity, along with nss-SO42-, and can identify specific local volcanic activities where no nss-SO42-. However, there are few comparable data except for some studies in the Antarctic region related to large-scale volcanic activity, because the F-content of polar snow and ice core is contained in sub-ppb. In this study, we reconstruct the F- record of 80 m shallow ice core obtained from GV7 (70° 41'S, 158° 52'E, 1950 m) and the main ion components record of 47 m shallow core from Styx (73° 51.10'S, 163° 41.22'E, 1623 m) located in Victoria Land, Antarctica. The concentration range of F- was found to be 0.05 μg / L to 2.12 μg / L in GV7 and 0.04 μg / L to 122 μg in Styx. As a result of calculating the contribution to the main origin of F-, F- showed the highest contribution of volcanoes and other factors (coal burning, etc.) than sea salt or crust. It is believed that the F- influx into Victoria Land mainly comes from volcanoes and other factors.
