Eight dredge hauls from BMR cruise 107 collected samples from seamounts in the Vening Meinesz chain south of Christmas Island. The samples contain calcareous nannofossils, foraminiferids, and macrofossils with ages ranging from Late Cretaceous to Holocene. The dataset is provided by the Australian Ocean Data Network.
Use Cases
- Reconstruct paleoenvironmental conditions based on Late Cretaceous shallow-water fossil assemblages.
- Analyze seamount subsidence and depositional depth changes based on Paleogene to Neogene microfossil records.
- Investigate debris flow events and sediment mixing based on samples containing lithologies of various ages.
- Model paleoclimate and ocean temperatures based on widespread Eocene shallow-water assemblages.
- Study volcanic activity timelines based on fresh volcanic content in some Eocene samples.
Strengths
- Samples cover a wide temporal range from Late Cretaceous to Holocene.
- Includes multiple fossil types: calcareous nannofossils, foraminiferids, and fragmentary macrofossils.
- Data originates from a specific research cruise (BMR cruise 107) with documented collection locations.
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 the specific seamount chain sampled.
