| Title | Antarctic surface air Beryllium-7 (Period-1:2014-2017) | ||
| Sub-Title | |||
| Data Summary | Beryllium-7 concentrations in surface air samples collected over the course of three Japanese Antarctic Research Expedition (JARE) cruises were analyzed. Air sampling was performed daily or twice daily in December 2014 (JARE-56), from December 2016 to March 2017 (JARE-58), and in December 2017 (JARE-59). These data are valuable for resolving daily variations in 7Be concentrations. | ||
