 "abstract": "253 audio and broadband magnetotelluric soundings from the Yeneena project, about 70 km south-west of the Telfer mine in Western Australia, recorded by Moombarriga Geoscience for Encounter Resources between 16 April and 4 July 2019. They lie on four regional profiles, YEN P1 to P4, and on a grid of 250 m spacing over the Aria magnetic anomaly, ringed by 14 more stations. Profile and ring soundings recorded overnight, grid soundings for at least 3 hours. Metronix ADU-07e and Phoenix MTU-5A systems recorded Ex, Ey, Hx, Hy and Hz on nominal 80 m dipoles, and every station was remote referenced. Served periods run 0.000096 s to 5,882 s and every station carries a tipper. Sensors were aligned to magnetic north and no declination is applied. The Metronix exports print project-wide acquisition dates rather than station dates; README.md gives each station's deployment day from the daily field report.",

  "changes_summary": "28 of the 253 served files, the Phoenix audio band exports of the Aria grid, carry a header date repair: the Geotools placeholder ACQDATE=01/01/01 is replaced by the deployment day the contractor's daily field activity report gives (27 files) or blanked where the report gives two (ARI509A), FILEDATE is rewritten from month-first to ISO 8601, and nine record lines follow >INFO. No other served file differs from its archive member by a byte and no number in any file is changed."
