LENS and NoPin CESM Ensemble: Ocean Biogeochemistry Data Along GO-SHIP Transects

CESM model ensemble means for apparent oxygen utilization, anthropogenic and preindustrial carbon, pCFC-12, and ideal age, created by Holly C. Olivarez et al. to study the influence of the Pinatubo eruption on long-term ocean changes. The data covers transects akin to A16N, A16S, P16N, P16S, SO4I, and SO4P. Model outputs are accessible via the Earth System Grid.

Use Cases

• Modeling the impact of the Pinatubo eruption on ocean carbon storage based on the described ensemble comparison.
• Analyzing long-term trends in apparent oxygen utilization (AOU) along major GO-SHIP transects.
• Studying the distribution of anthropogenic versus preindustrial carbon in the ocean using the provided model outputs.
• Validating ocean circulation and ventilation timescales using ideal age and pCFC-12 tracer data.

Strengths

• Data is derived from the Community Earth System Model (CESM), a widely used and freely available climate model.
• Includes ensemble means from two distinct experimental setups (LENS and NoPin) for comparative analysis.
• Covers multiple key ocean biogeochemical tracers: AOU, anthropogenic carbon, preindustrial carbon, pCFC-12, and ideal age.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data volume are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
