Eocene-Oligocene Atmospheric CO2 Reconstruction from Tanzania d11B

Paleoclimate data from the Eocene-Oligocene transition period, focusing on atmospheric CO2 (pCO2atm) reconstructions derived from boron isotope (d11B) measurements. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, is associated with a 2009 study by Pearson et al. and pertains to a site in Eastern Africa.

Use Cases

• Reconstructing ancient atmospheric pCO2atm levels using the d11B proxy from marine carbonates.
• Analyzing climate forcing trends across the Eocene-Oligocene boundary with time-series data.
• Calibrating Earth system models for the Paleogene period using Eastern African paleoclimate records.
• Correlating boron isotope (d11B) variations with other paleoclimate parameters for the specified location.

Strengths

• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Provides a specific geochemical proxy (d11B) for a key climate variable (pCO2atm).
• Focuses on a critical climate transition period (Eocene-Oligocene).

Limitations

• Exact temporal coverage in calendar years before present is listed as unavailable in the source metadata.
• The sample size (number of data points/rows) and specific column structure are unknown.
• Geographic coverage is limited to a single Eastern African location, reducing spatial representativeness.
