Lord Howe Rise Seismic and Bathymetry Data from 2016 Survey

Multi-channel seismic reflection and bathymetry data from a 2016 marine geophysical survey offshore eastern Australia. The data includes a processed ~900 km east-west profile and grids covering rift basins up to 3.5 km deep. This dataset was presented at the 2017 IAG-IASPEI conference and is provided by Geoscience Australia.

Use Cases

• Modeling Late Cretaceous rifting processes based on seismic reflection images of the Tasman Basin and Lord Howe Rise.
• Analyzing variations in normal faulting and basin evolution based on contrasting rift basin data.
• Interpreting sedimentary sequences and unconformities within the ~3.5 km thick Middleton Basin.
• Mapping the structure of the Dampier Ridge and its relationship to the Tasman Basin based on seismic boundaries.

Strengths

• Includes a regional seismic profile approximately 900 km long.
• Data reveals rift basins with depths up to 3.5 km.
• Contains both pre-stack depth-migrated and pre-stack time-migrated seismic reflection data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
