Biostratigraphy of Rig Seismic samples from Vening Meinesz seamounts, Christmas Island are

Samples from eight dredge hauls collected during BMR cruise 107 from several seamounts in the Vening Meinesz chain, south of Christmas Island, yielded calcareous nannofossils, foraminiferids, and fragmentary macrofossils with ages ranging from Late Cretaceous to Holocene. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-23.

Use Cases

• Reconstructing paleoenvironmental conditions based on fossil assemblages indicating shallow-water to bathyal depths.
• Analyzing the timing and impact of volcanic activity based on fresh volcanic content in samples.
• Studying debris flow processes based on mixed-age samples suggestive of sediment transport.
• Modeling seamount subsidence history based on changes in depositional depth from Cretaceous to Neogene.

Strengths

• Samples span a long temporal range from the Late Cretaceous to the Holocene.
• Contains multiple fossil groups: calcareous nannofossils, foraminiferids, and macrofossils.
• Data originates from a specific research cruise (BMR cruise 107) with a defined geographic focus.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
