IODP Expedition 363 Sediment Coarse Fraction and Fish Teeth Abundance Data

Sediment data from the International Ocean Discovery Program (IODP) Expedition 363, funded by NERC grant NE/P016456/1. The dataset contains measurements of sediment coarse fraction percentage (>63 microns) and fish teeth abundance within that fraction, collected to study the evolution of the Pacific warm pool over the past 15 million years. It was contributed by the British Geological Survey (BGS) and last updated in April 2026.

Use Cases

• Modeling past climate system drivers based on sediment coarse fraction data.
• Analyzing the evolution of the Pacific warm pool based on marine fossil proxy records.
• Investigating links between ocean basin changes and biological ecosystems based on fish teeth abundance.
• Studying long-term carbon cycling in the low-latitude Pacific based on geochemical analyses.

Strengths

• Data originates from the authoritative International Ocean Discovery Program (IODP).
• Dataset is associated with a specific NERC research grant (NE/P016456/1).
• Contributing organization is the British Geological Survey (BGS).

Limitations

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