Capricorn Basin: Marine Seismic Survey Data

Geoscience Australia's 1989 marine survey acquired 2900 km of multi-channel seismic reflection data off southeast Queensland. The dataset focuses on the structure and petroleum potential of the Capricorn and northern Tasman Basins, also including sonobuoy refraction, gravity, magnetic, and bathymetric data. It provides ties to the Aquarius-1 and Capricorn-1A wells and characterizes Late Cretaceous to Recent basin evolution.

Use Cases

• Mapping subsurface basin structure based on seismic reflection profiles.
• Analyzing petroleum resource potential from stratigraphic sequences.
• Correlating regional geology using ties to deep offshore wells.
• Integrating geophysical models with gravity and magnetic data.

Strengths

• Contains a substantial 2900 km of seismic reflection data from a major survey.
• Integrates multiple geophysical data types (seismic, gravity, magnetic, bathymetry).
• Provides direct ties to key regional wells (Aquarius-1, Capricorn-1A).

Limitations

• Specific column names, row counts, and file sizes are not provided in the metadata.
• The dataset is from a single survey in 1989, limiting temporal coverage to that period.
• License and author information are not specified.
