Antarctic Krill Physiology Under Elevated CO2 Conditions

Long-term experimental data tracks krill growth, mortality, and physiology under CO2 levels ranging from 400 to 4000 ppm over one year. The dataset was produced by the Australian Antarctic Data Centre and last updated in February 2016.

Use Cases

• Model krill mortality rates as a function of CO2 concentration and water chemistry parameters.
• Analyze correlations between growth metrics and specific biochemistry measurements from the experiment.
• Assess physiological stress responses in krill across the 400-4000 ppm CO2 gradient.

Strengths

• Data covers a full year-long experimental period.
• Exposure conditions span a wide CO2 range from 400 to 4000 ppm.

Limitations

• Sample size and row count are unknown.
• Data is from a single experiment, limiting generalizability.
• The dataset has not been updated since 2016.
