Coastal Phytoplankton Community Response to Ocean Alkalinity Enhancement Over 22 Days

A 22-day microcosm experiment monitored plankton communities during a spring bloom after increasing seawater alkalinity by approximately 497 µmol/kg. The data, hosted by the Australian Ocean Data Network, explores two CO2 equilibrium scenarios. Dynamics of carbonate chemistry, dissolved inorganic nutrients, particulate matter, and chlorophyll a were tracked.

Use Cases

• Modeling phytoplankton bloom dynamics based on monitored chlorophyll a and nutrient levels.
• Assessing carbonate system changes based on alkalinity enhancement and CO2 equilibrium scenarios.
• Evaluating particulate matter production based on monitored changes over the experimental period.

Strengths

• Experiment duration of 22 days captures a full spring bloom event.
• Alkalinity was increased by a precise amount (~497 µmol/kg) in controlled treatments.
• Monitors multiple interacting systems: plankton, chemistry, nutrients, and particulate matter.

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/temporal bias inherent to data_gov_au.
