Ocean Alkalinity Enhancement Incubation Experiments in the Equatorial Pacific

19 ship-based experiments conducted in the Equatorial Pacific to investigate the impacts of Ocean Alkalinity Enhancement (OAE) on marine plankton. The dataset, hosted by the Australian Ocean Data Network and last updated in April 2026, monitored parameters including chlorophyll-a, nutrients, trace elements, alkalinity, Fv/Fm, pH, and flow cytometry. Experiments simulated alkalinity enhancements between 29 and 16 μmol kg-1 using three OAE sources: NaOH, olivine, and steel slag.

Use Cases

• Modeling phytoplankton community response to chemical perturbations based on chlorophyll-a and Fv/Fm measurements.
• Comparing the environmental impacts of different OAE source materials (NaOH, olivine, steel slag) based on monitored nutrient and trace element data.
• Assessing the side-effects of OAE against climate change impacts based on experimental alkalinity enhancement simulations.
• Analyzing changes in water chemistry and primary productivity based on total alkalinity and pH time-series data.

Strengths

• 19 distinct ship-based experiments provide multiple data points for analysis.
• Monitored parameters include multiple biological and chemical indicators (chlorophyll-a, nutrients, trace elements, alkalinity, Fv/Fm, pH, flow cytometry).
• Experiments simulated a defined range of alkalinity enhancements (29-16 μmol kg-1).

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the Equatorial Pacific study region.
