Description
A 2015-2017 proposal for deep stratigraphic drilling on the Lord Howe Rise, a submerged continental ribbon in the southwest Pacific. The dataset, associated with Geoscience Australia and JAMSTEC, outlines objectives to understand tectonic cycles, Cretaceous paleoclimate, and sub-seafloor microbial life over a 100-million-year timeframe. Preparations included 2D seismic surveys in 2016 and 2017 to map crustal structure and acquire geotechnical data for planned drilling in 2019 or 2020.
Use Cases
Modeling plate tectonic cycles and continental evolution based on the proposed drilling into Cretaceous and older sediments.
Reconstructing high-latitude Cretaceous paleoclimate based on proposed biomarker and micropaleontology data recovery.
Studying the evolution of sub-seafloor microbial life over a 100-million-year timeframe as outlined in the drilling objectives.
Analyzing crustal structure and basin architecture using the 2D seismic reflection and refraction data mentioned from site surveys.
Strengths
Proposal was rated 'excellent' by the IODP Science Evaluation Panel in January 2017.
Seismic surveys helped constrain crustal thickness to about 20 km beneath the Lord Howe Rise.
Drilling plan targets a deep stratigraphic well extending up to about 2500 m below the seafloor.
Limitations
Row count is unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
Data may reflect geographic bias inherent to the specific study region of the Lord Howe Rise.
