| Sub-Title | Continuous digital data by infrasound array observation at SYO |
| Data Summary | Characteristic features of infrasound waves observed at Antarctica reveal the physical interaction involving surface environmental variations in the Antarctic continent and surrounding Southern Oceans. A single infrasound sensor has been continuously recorded since 2008 at Syowa Station (SYO; 39E, 69S), East Antarctica, as one of the projects of the International Polar Year (IPY2007-2008). The continuously recorded data in the last few seasons clearly represent a contamination of the background oceanic signals (microbaroms) during whole seasons. In austral summer in 2013,infrasound array was installed at SYO (in 100 m spacing triangle) by using Chaparral physics Model-25 sensors. The newly established infrasound array clearly detecte the propagating directions and frequency dependency of the microbaroms from the Southern Ocean. |
