Deep-Sea Sediment Core Analyses from Southwest Victoria and Tasmania

Sedimentological data from three research cruises conducted off southwest Victoria and Tasmania between 1985 and 1988. The dataset documents laboratory analyses on 135 cores, including grain size, calcium carbonate (CaCO3), and total organic carbon (TOC) measurements. The work was performed by the Bureau of Mineral Resources (BMR) and partners to model sedimentation on the continental margin.

Use Cases

• Modeling historical sedimentation patterns based on grain size and CaCO3 variations.
• Reconstructing paleoenvironmental conditions from core sample geochemistry.
• Correlating sedimentological data with regional seismic reflection data for stratigraphic interpretation.

Strengths

• Data originates from 135 distinct sediment cores collected on three dedicated research cruises.
• Analyses include multiple complementary measurements: grain size, CaCO3, and TOC.
• Core lengths are documented, ranging from 0.02 meters to 7.78 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; the last metadata update is 2026-06-05.
