Lord Howe Rise Seismic Reflection and Bathymetry Data from 2016 Survey

Multi-channel seismic reflection and bathymetry data from a 2016 marine survey along a ~900 km profile at 27.2°S. The processed data, presented at a 2017 conference, reveals rift basins up to 3.5 km deep and helps constrain the Late Cretaceous formation of the Lord Howe Rise continental ribbon. The dataset is provided by Geoscience Australia Data.

Use Cases

• Modeling tectonic rift processes based on interpreted syn-rift and post-rift sedimentary sequences.
• Analyzing basin evolution based on contrasting normal faulting patterns described in two rift basins.
• Mapping subsurface geology based on pre-stack depth-migrated seismic reflection images covering oceanic to continental crust.
• Studying sedimentary basin stratigraphy based on identified unconformities and strata thicknesses up to ~3.5 km.

Strengths

• Includes a regional east-west profile approximately 900 km long, providing broad spatial coverage.
• Data reveals specific geological features, including rift basins up to 3 km deep and a sedimentary basin ~3.5 km thick.
• Contains both pre-stack depth-migrated and pre-stack time-migrated seismic reflection data for different analytical purposes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific marine survey corridor.
