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

Samples from eight dredge hauls collected during BMR cruise 107 from seamounts in the Vening Meinesz chain, south of Christmas Island, yielded calcareous nannofossils, foraminiferids, and macrofossils. The dataset, hosted by the Australian Ocean Data Network, provides age ranges from Late Cretaceous to Holocene. It was last updated on 2026-05 04.

Use Cases

• Reconstructing paleoenvironmental depths based on Late Cretaceous shallow-water to upper bathyal assemblages.
• Analyzing volcanic history and seamount formation timing based on age ranges from Albian to Maastrichtian.
• Investigating debris flow processes based on samples described as mixtures of various lithologies and ages.
• Studying paleoclimate and latitudinal shift based on evidence of warm seas at far southern latitudes during the Maastrichtian.
• Modeling seamount subsidence based on depositional depth changes from Paleogene bathyal to Neogene bathyal environments.

Strengths

• Covers a wide temporal range from Late Cretaceous to Holocene.
• Includes multiple fossil groups: calcareous nannofossils, foraminiferids, and fragmentary macrofossils.
• Samples originate from eight distinct dredge hauls across several seamounts.

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/temporal bias inherent to the specific cruise and sampling locations.
