Experimental data from deck-board incubations assessing the biological impacts of ocean alkalinity enhancement in the Southern Ocean. Measurements include carbonate chemistry, macronutrients, chlorophyll-a, and plankton community composition from five sites during a voyage in January–March 2024. The dataset was generated to distinguish effects of alkalinity change from collateral nutrient and trace-metal release.
Use Cases
- Modeling phytoplankton growth responses based on alkalinity and nutrient measurements.
- Comparing community composition shifts based on genus-level microscopy data.
- Assessing ecological risks of carbon dioxide removal strategies based on experimental outcomes.
- Evaluating trace metal release impacts based on ICP-MS data from dark leaching experiments.
Strengths
- Data spans five sites from subantarctic to sea-ice regions, providing geographic diversity.
- Includes measurements from beginning and end of 5–8 day incubations for temporal comparison.
- Compares three specific alkalinity sources: sodium hydroxide, ground olivine, and steel slag.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
