Seismic reflection data from the Wilkes Land and Terre Adelie margins in East Antarctica reveals two major sedimentary basins containing over 9 km of sediment. The Australian Ocean Data Network hosts this dataset, which identifies four seismic megasequences bounded by basement and unconformities. The data was last updated on 2026-04-16.
Use Cases
- Modeling basin evolution based on identified seismic megasequences.
- Estimating sediment thickness and distribution in the Sabrina and Budd Coast Basins.
- Correlating geological timelines between the Antarctic and Australian margins.
- Investigating sediment provenance linked to the Totten Glacier sub-glacial basin.
Strengths
- Identifies sedimentary basins with more than 9 km of sediment thickness.
- Defines four distinct seismic megasequences (MS4 to MS1) with interpreted age boundaries.
- Provides seismic correlation with the Australian margin for age interpretation.
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.
