Geoscience Australia's SNOWS program provides a regional deep-seismic framework dataset for the southern North West Shelf, a prospective hydrocarbon region. The dataset includes results from SNOWS-1 (1991, 1654 km of data tied to 20 wells) and SNOWS-2 (1992, over 2800 km along 13 lines tied to 21 wells), showing reflections down to 12 seconds two-way time. The data were acquired to determine the deep crustal structure and assess its control on major hydrocarbon fields and plays.
The primary available file formats appear to be pre-cruise reports (HTML, PDF), not the raw or processed seismic data itself. The 'last updated' date (2026) is in the future relative to the survey dates, which may indicate a metadata error.
