IODP Site U1480: Biostratigraphy and Carbonate Stable Isotope Measurements

Nannofossil biostratigraphy, 46 stable bulk carbonate stable isotope measurements (oxygen and carbon), and 71 organic and inorganic carbon percentage measurements from between 1313.71 and 1326.82 meters below sea floor at IODP Site U1480. The dataset was produced under NERC grant NE/P021182/1 and is associated with the British Geological Survey. It was last updated on 2026-04-09.

Use Cases

• Establishing age models for sediment cores based on nannofossil biostratigraphy.
• Reconstructing past ocean temperature and productivity based on stable oxygen and carbon isotope measurements.
• Analyzing changes in carbon burial and carbonate dissolution based on organic and inorganic carbon percentages.
• Correlating climate proxy records from a specific drill site with regional or global climate events.

Strengths

• Includes 46 stable isotope measurements for both oxygen and carbon.
• Provides 71 measurements for organic and inorganic carbon percentages.
• Data is precisely located between 1313.71 and 1326.82 meters below sea floor.

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.
