The obtained 11 years of infrasound data enable us to examine characteristics of infrasound behavior around SYO. Spectral analysis of recorded data clearly shows continuous arrivals of microbaroms from the southern ocean and weak annual change of the energy. Array analysis of the 3-sensor observation data detected infrasound signals generated by ice-related activities around SYO.Polar Data Journal445542020-03National Institute of Polar Research2432-6771https://doi.org/10.17592/001.2019070501publisherhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=22&item_no=1&attribute_id=22&file_no=1CC BYhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=22&item_no=1&attribute_id=22&file_no=2Ⓒ 2020 National Institute of Polar Researchhttps://pdr.repo.nii.ac.jp/?action=repository_action_common_download&item_id=22&item_no=1&attribute_id=22&file_no=4Ⓒ 2020 National Institute of Polar ResearchAtmospheric science/ClimatologySolid earth geophysics/Seismology2020-02-25
