Snow Crab Juvenile Survival and Growth Under Ocean Acidification, 2021-2022

Laboratory data from Kodiak, Alaska tracks survival, growth, and morphology of juvenile snow crabs exposed to three pH levels. The dataset is associated with a NOAA study under review, focusing on the effects of ocean acidification on a federally managed species. Observations were recorded from April 2021 to June 2022.

Use Cases

• Modeling survival rates of juvenile snow crabs based on pH exposure levels.
• Analyzing growth metrics under controlled acidification conditions.
• Studying morphological changes in response to reduced pH.
• Comparing physiological responses across different life stages mentioned in the platform tags.

Strengths

• Data from a controlled laboratory experiment with three distinct pH treatments (ambient, 7.8, 7.5).
• Associated with a formal NOAA study currently under peer review.
• Covers multiple response variables: survival, growth, and morphology.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The complete methods are under review and must be read prior to data use.
