The Australian Ocean Data Network hosts processed seismic reflection and bathymetry data from a 2016 marine survey. The dataset includes a ~900 km east-west profile at 27.2°S, covering the Tasman Basin to the Lord Howe Rise, and grids of pre-stack time-migrated lines over two rift basins. The data was presented at the 2017 IAG-IASPEI conference.
Use Cases
- Modeling Late Cretaceous rifting processes based on seismic reflection images.
- Analyzing sedimentary basin evolution based on described syn-rift and post-rift sequences.
- Comparing rift basin structures based on contrasting normal faulting patterns.
- Mapping subsurface geology based on pre-stack depth-migrated seismic profiles.
- Studying unconformities and stratigraphy based on the described Middleton Basin features.
Strengths
- Includes a regional seismic profile approximately 900 km long.
- Processed data includes both pre-stack depth-migrated and pre-stack time-migrated images.
- Describes specific geological features such as rift basins up to 3 km deep and sedimentary basins up to ~3.5 km thick.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au.
