Geoscience Australia and JAMSTEC have collaborated since 2014 to collect deep rock cores from Zealandia basins. Analysis of these cores aims to unlock a 100-million-year history of geology, tectonics, climate, and microbial life. A proposal for scientific drilling to several kilometres below the seafloor has been approved by the International Ocean Discovery Program.
Use Cases
- Modeling tectonic stretching and basin formation based on Zealandia's geological history.
- Studying past climate dynamics based on sediment core analysis.
- Investigating the limits of life on Earth based on ancient microbial life evidence.
- Analyzing continental fragment separation processes based on Zealandia's fracture from Australia.
Strengths
- Collaboration involves two major scientific agencies (Geoscience Australia and JAMSTEC) since 2014.
- Proposal is approved by a major international program (International Ocean Discovery Program).
- Analysis targets a 100-million-year geological and climatic history.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
