Coastal Phytoplankton Community Response to Ocean Alkalinity Enhancement Over 22 Days

A 22-day microcosm experiment monitored plankton communities, carbonate chemistry, dissolved inorganic nutrients, particulate matter, and chlorophyll a dynamics during a spring bloom. Alkalinity was increased by approximately 497 µmol/kg under two CO2 equilibrium scenarios. The data originates from the Australian Ocean Data Network and was last updated in July 2026.

Use Cases

• Modeling phytoplankton bloom dynamics based on monitored chlorophyll a and nutrient levels.
• Assessing carbonate chemistry changes based on alkalinity enhancement treatments under different CO2 equilibria.
• Evaluating the ecological impact of ocean alkalinity enhancement based on monitored plankton community composition.

Strengths

• Data covers a 22-day period capturing a spring bloom event.
• Experiment includes a specific alkalinity increase of ~497 µmol/kg.
• Treatments compare two distinct CO2 equilibrium scenarios with the atmosphere.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
