IODP Deep Stratigraphic Drilling Data for Lord Howe Rise Tectonics and Climate

The Lord Howe Rise in the southwest Pacific is the focus of a deep stratigraphic drilling proposal to core Cretaceous and older sediments up to 2500 meters below the seafloor. Geoscience Australia and JAMSTEC submitted the proposal to the International Ocean Discovery Program in 2015, with drilling planned for 2019 or 2020. Preparations included 2D seismic surveys in 2016 and 2017 to map crustal structure and acquire geotechnical data.

Use Cases

• Modeling plate tectonic cycles and continental evolution based on data from a continental crustal ribbon.
• Reconstructing Cretaceous paleoclimate based on high-latitude biomarker and micropaleontology data.
• Testing evolutionary concepts for sub-seafloor microbial life over a 100-million-year timeframe.
• Analyzing crustal structure and sedimentary basin architecture based on 2D seismic reflection and refraction data.

Strengths

• Proposal rated 'excellent' by the IODP Science Evaluation Panel in January 2017.
• Seismic surveys acquired data to map regional crustal structure and constrain basement depth.
• Drilling aims to recover a geological record spanning over 100 million years.

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 the specific survey area on the Lord Howe Rise.
