Pulleniatina Coiling Data: Foraminifera Morphology from IODP Expedition 363

Pulleniatina U1486 coiling sequence data from the International Ocean Discovery Program (IODP) Expedition 363, supported by NERC grant NE/P016375/1. The dataset relates to the study of the Indo-Pacific Warm Pool's climatic history over the past 15 million years. Professor Paul Pearson of the British Geological Survey contributed to the expedition, specializing in planktonic foraminifera for biostratigraphy and evolutionary study.

Use Cases

• Reconstructing past sea surface temperature changes based on foraminifera coiling patterns mentioned in the description
• Conducting biostratigraphic dating of marine sediments based on the described focus on Pulleniatina for stratigraphy
• Modeling evolutionary speciation and extinction in plankton lineages based on the described case study of Pulleniatina
• Analyzing the relationship between ocean current patterns and plankton morphology based on described links to sea level fluctuations

Strengths

• Data is linked to a specific, peer-reviewed scientific ocean drilling expedition (IODP Expedition 363)
• Focuses on a specific evolutionary lineage (Pulleniatina) with described potential for detailed morphological study
• Temporal context spans up to 15 million years, including glacial cycles and the Miocene epoch

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
