Ocean Alkalinity Enhancement Incubation Experiments in the Equatorial Pacific

19 ship-based experiments simulated Ocean Alkalinity Enhancement (OAE) in the Equatorial Pacific to study impacts on marine plankton. The experiments tested three OAE sources—NaOH, olivine, and steel slag—with alkalinity enhancements between 29-16 μmol kg-1. Monitored parameters included chlorophyll-a, nutrients, trace elements, total alkalinity, Fv/Fm, pH, and flow cytometry data.

Use Cases

• Modeling phytoplankton community response to alkalinity enhancement based on chlorophyll-a and Fv/Fm measurements.
• Comparing the biogeochemical impacts of different OAE sources (NaOH, olivine, steel slag) based on nutrient and trace element data.
• Assessing potential side-effects of OAE against climate change impacts on marine ecosystems.
• Calibrating ocean carbon cycle models using experimental total alkalinity and pH data.

Strengths

• Includes data from 19 distinct ship-based incubation experiments.
• Simulates realistic alkalinity enhancements within a defined range of 29-16 μmol kg-1.
• Monitors multiple key parameters including chlorophyll-a, nutrients, trace elements, and photosynthetic efficiency (Fv/Fm).

Limitations

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