BMR Cruise 107: Seabed Morphology and Offshore Resources around Christmas Island

BMR Cruise 107 data from the Australian Ocean Data Network describes seabed morphology and non-living resources around Christmas Island in the Indian Ocean. The dataset was collected in January 1992 using the RV Rig Seismic vessel. It includes information on the island's geology, bathymetry, and phosphate deposits.

Use Cases

• Mapping seabed morphology for maritime boundary negotiations based on bathymetric survey data.
• Assessing offshore resource potential based on descriptions of volcanic bedrock and phosphate deposits.
• Studying the geological evolution of oceanic plateaus based on the description of the Christmas Rise and its Late Cretaceous crust.

Strengths

• Dataset is associated with a specific, documented research cruise (BMR Cruise 107) conducted in January 1992.
• Description provides specific geographic context, including distances (e.g., 1600 km from Australia's Northwest Cape) and depths (e.g., Java Trench >6500 m deep).
• Includes historical context on phosphate mining activity, including production figures (nearly 1,000,000 tonnes/year until 1987).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are PDF and HTML, which may require extraction to access structured data.
