7Be concentrations in surface air over the Indian sector of the Southern Ocean and at two Japanese coastal Antarctic stations in the summers of 2014/15, 2016/17, and 2017/18

7Be 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 as they cover an extensive area of the Antarctic region for which there is currently little data. The data were collated in CSV format and are available from the National Institute of Polar Research (NIPR) at https://doi.org/10.17592/002.2022040392.
