<abstract>
<p>&lt;p style=&quot;font-weight: 400;&quot;&gt;&lt;span&gt;Long, continuous infrasound records from the Antarctic coast are rare, but they provide passive, all-weather observations of cryospheric, oceanic, and atmospheric processes. We present a decade-scale catalog of coherent atmospheric infrasound transients recorded by the three-element KIS (KOPRI InfraSound) array at Jang Bogo Station, Terra Nova Bay, East Antarctica. Across 2,507 array-days spanning 2017&amp;ndash;2026, we identified 23,768 coherent acoustic transients using an STA/LTA coincidence detector followed by inter-element coherence and slowness analysis. Of these, 22,711 were recorded in the 100 Hz HDF stream and 1,057 in the 20 Hz BDF stream, which bridges a 2021&amp;ndash;2022 configuration gap. Each catalog entry includes detection time, duration, inter-element coherence, wavefront back-azimuth, apparent velocity, signal-to-noise ratio, nominal-equivalent pressure, directional sector, and recording stream. The apparent-velocity distribution is sharply concentrated around 333 m s⁻&amp;sup1;, consistent with acoustic propagation. The median event duration is 6.5 s, and the catalog contains both impulsive and emergent waveform classes. The catalog and its per-event waveform windows are openly archived under a CC BY 4.0 license at Zenodo (&lt;a href=&quot;https://doi.org/10.5281/zenodo.21882394&quot;&gt;https://doi.org/10.5281/zenodo.21882394&lt;/a&gt;) &lt;/span&gt;&lt;span&gt;(Park et al., 2026d)&lt;/span&gt;&lt;span&gt;, and the catalog is mirrored at the Korea Polar Data Center (&lt;a href=&quot;https://doi.org/10.22663/KOPRI-KPDC-00003159&quot;&gt;https://doi.org/10.22663/KOPRI-KPDC-00003159&lt;/a&gt;) &lt;/span&gt;&lt;span&gt;(Park et al., 2026f)&lt;/span&gt;&lt;span&gt;. Worked examples show that the catalog captures the coherent infrasound of the 2022 Hunga Tonga eruption and a transient from the direction of David Glacier that follows a local glacial earthquake. The dataset provides a reusable resource for cryo-acoustic and infrasound-monitoring studies on the Antarctic margin. Physical interpretation of the directional source families is presented in a companion analysis paper.&lt;/span&gt;</p>
