Multi-channel seismic reflection and bathymetry data collected offshore eastern Australia during a 2016 marine survey. The processed data includes a regional east-west seismic profile approximately 900 km long at 27.2°S, covering the Tasman Basin, Dampier Ridge, Middleton Basin, and Lord Howe Rise. This dataset was presented at the 2017 IAG-IASPEI conference and is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling Late Cretaceous rifting processes based on described syn-rift and post-rift sedimentary sequences.
- Analyzing the structure of rift basins up to 3.5 km thick based on the described stratigraphy of the Middleton Basin.
- Comparing normal faulting variations within syn-rift sequences based on the contrasting evolution described for two rift basins on the Lord Howe Rise.
- Investigating early transform faulting signatures based on the described buried basins within the Tasman Basin.
Strengths
- Includes a long regional seismic profile approximately 900 km in length.
- Describes specific geological features like rift basins up to 3.5 km thick and an unconformity separating strata.
- Data is based on a dedicated multi-leg marine geophysical survey conducted in 2016.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The primary file format is HTML, which likely contains reports or metadata rather than raw structured data files.
