Lord Howe Rise Seismic and Bathymetry Data from 2016 Marine Survey

Multi-channel seismic reflection and bathymetry data from a 2016 marine survey constrains the Late Cretaceous rifting of eastern Gondwana. The processed data includes a ~900 km long east-west profile and grids covering two rift basins on the Lord Howe Rise. This dataset was presented at the 2017 IAG-IASPEI conference and is hosted by the Australian Ocean Data Network.

Use Cases

• Modeling the tectonic evolution of the Tasman Basin based on identified buried basins and transform faulting evidence
• Analyzing rift basin stratigraphy and faulting patterns based on the described syn-rift and post-rift sequences
• Interpreting sedimentary basin thickness and unconformities based on the ~3.5 km thick Middleton Basin data
• Comparing contrasting rift basin evolution based on the pre-stack time-migrated seismic grids of two Lord Howe Rise basins

Strengths

• Includes a regional ~900 km long seismic reflection profile
• Contains data on rift basins with depths up to 3 km and sedimentary thickness up to ~3.5 km
• Provides both pre-stack depth-migrated and pre-stack time-migrated processed seismic images

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 data_gov_au
