Southern Ocean Calcifier Vulnerability to Acidification

Southern Ocean marine calcifiers are analyzed for their vulnerability to ocean acidification, a process projected to lower surface seawater pH by ~0.3 by 2100. This dataset synthesizes a review and meta-analysis, linking biological responses like shell state and growth rate to skeletal mineralogy. It considers species' geographic range, biological traits, and potential resilience strategies.

Use Cases

• Projecting species risk based on skeletal mineralogy (e.g., aragonite vs. low-Mg calcite).
• Analyzing geographic vulnerability patterns of Southern Ocean taxa.
• Synthesizing experimental results on biological responses like development and shell state.
• Informing conservation strategies by evaluating species traits and potential adaptation mechanisms.

Strengths

• Synthesizes a quantitative meta-analysis with a review, providing a dual-method overview.
• Focuses on a high-impact region (the Southern Ocean) identified as first and most severely affected by acidification.
• Integrates multiple analysis dimensions: species mineralogy, geographic range, biological traits, and physiological processes.

Limitations

• Key metadata is missing: specific column names, row count, file size, and license information are not provided.
• The dataset's structure and the primary data underlying the meta-analysis are not described.
• Update timestamps conflict, with one source showing a last update of 2026-04-04 and another showing 2026-04-16.
