Phytoplankton Growth Rates Under Nickel Stress for Ocean Alkalinity Enhancement Research

Data from a master's thesis project hosted by the Australian Ocean Data Network measures the effect of nickel on phytoplankton. It contains growth rates for 11 phytoplankton species under different nickel concentrations, with photo-physiological data from Fast Repetition Rate fluorometry. The data was analyzed using generalized additive models and plotted in RStudio.

Use Cases

• Modeling phytoplankton growth response to nickel concentrations based on the experimental treatments described.
• Analyzing the relationship between photosynthetic efficiency (Fv/Fm) and nickel stress using the FRRf data mentioned.
• Assessing potential ecological side-effects of ocean alkalinity enhancement based on the multi-species growth rate data.

Strengths

• Includes data for 11 distinct phytoplankton species, allowing for comparative analysis.
• Contains both growth rate and photo-physiological (Fv/Fm, SigmaPSII) measurements, providing multiple response variables.
• Data was analyzed with statistical models (GAMs), suggesting a structured analytical approach.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
