Red King Crab Survival Under Ocean Acidification and Warming

A 184-day laboratory experiment tested the effects of two pH levels and three temperatures on young red king crab (Paralithodes camtschaticus). Mortality increased with reduced pH and higher temperatures, showing complex synergistic and antagonistic interactions, with only 3% survival in the most extreme treatment. The study found no significant effect of these stressors on crab growth or morphology.

Use Cases

• Modeling population mortality under combined climate stressors based on survival rates across six treatments.
• Analyzing synergistic versus antagonistic stressor interactions from the crossed experimental design.
• Assessing climate resilience in a key fishery species by examining growth and morphology metrics.
• Calibrating ecosystem models with empirical data on temperature and pH thresholds for crab survival.

Strengths

• Data originates from a long-term (184-day) controlled laboratory experiment, allowing for causal inference.
• The fully crossed experimental design with six treatments enables analysis of multi-stressor interactions.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and reuse potential.

Limitations

• Key metadata is missing or conflicting: column names, row counts, and specific license information are not provided.
• The last update date conflicts between sources (2013 vs. 2026), creating uncertainty about data currency.
• The dataset's scale and completeness are unclear due to the absence of size and row count information.
