Geoscience Australia and JAMSTEC lead an international proposal for deep stratigraphic drilling on the Lord Howe Rise continental ribbon. The dataset likely contains planning documents, seismic survey results, and site characterization data for a 2019/2020 drilling campaign targeting Cretaceous sediments and basement rocks. Preparations include 2D seismic reflection and refraction surveys conducted in 2016 and a planned 2017 geotechnical survey.
Use Cases
- Modeling crustal structure and basin architecture based on seismic survey data mentioned in the description
- Analyzing Cretaceous paleoclimate and ocean biogeochemistry based on planned biomarker and micropaleontology recovery
- Investigating the evolution of sub-seafloor microbial life over a 100-million-year timeframe as outlined in the proposal objectives
- Studying the tectonic role of continental crustal ribbons like the Lord Howe Rise
Strengths
- Proposal rated 'excellent' by the IODP Science Evaluation Panel in January 2017
- Seismic survey data acquired in 2016 provides constraints on crustal structure and basement character
- Drilling planned to extend to a depth of up to about 2500 m below the seafloor
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
