Seasonal differences in microbaroms and highfrequency harmonic tremors were particularly investigated. Infrasound data were strongly involved in local dynamics of surface surroundings. The microbaroms have comparativelylow amplitudes in austral winters by spreadingpart of sea-ice about LHB, with lessening oceanic swell filling effects. The additionaldetails of periodicDifferences in microbaroms amplitudes were produced by the affections of a number of tempeststhroughout whole year and snow gatheringdone the porousHoses on the infrasound station at SYO. In difference, non-linear highfrequency harmonic tremors remained considered to be produced by the katabatic winds from Antarctic landform flowing in northeast prevailingpositioning. The high-frequency tremors had appearances of daily differences in specificin austral summer. It is essential to continue additionalthan a few years of observation in order to classifyassociations with weatheralteration and global heating effects in the Antarctic. Endless measurement of infrasound in the coastal margin of Antarctica is a substitution for checking multisphere communicationamong the landforms and nearby Southern Ocean
