Seasonal Iron and Manganese Limitation of Subantarctic Phytoplankton

Data from the Australian Ocean Data Network details results from three shipboard bioassay experiments conducted south of Tasmania. The dataset captures seasonal variation in phytoplankton growth limitation by iron and manganese, with flow cytometry analysis of specific taxa. Findings suggest iron limitation is strongest in summer, while manganese effects are more subtle and taxon-specific.

Use Cases

• Analyzing seasonal patterns of iron limitation in phytoplankton based on bioassay response data.
• Investigating co-limitation dynamics between iron, manganese, and silicic acid from experimental treatments.
• Studying taxon-specific growth responses to nutrient additions using flow cytometry data.
• Modeling the impact of micronutrient availability on the Southern Ocean carbon sink.

Strengths

• Data is derived from three distinct shipboard experiments, providing seasonal coverage.
• Analysis includes flow cytometry, allowing for taxon-specific insights into phytoplankton community responses.

Limitations

• Critical metadata such as row count, specific column names, and file size are unavailable across all sources.
• License and author information is not provided, limiting clarity on reuse permissions.
• The dataset's structure and specific measurement variables are not detailed.
