Laboratory experiments present the first data on quick and hydrated lime dissolution in natural seawater for Ocean Alkalinity Enhancement. Total alkalinity and dissolved inorganic carbon concentrations were collected after various alkalinity increases using different alkaline minerals. The dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-07-13.
Use Cases
- Calibrating numerical models of ocean carbon capture based on experimental alkalinity and dissolved inorganic carbon measurements.
- Comparing the dissolution efficiency of different alkaline minerals for Ocean Alkalinity Enhancement.
- Validating laboratory protocols for measuring total alkalinity via potentiometric titration.
- Assessing the relationship between alkalinity increase and dissolved inorganic carbon concentration in seawater.
Strengths
- Represents the first laboratory experiments on this topic, providing empirical data where most knowledge relies on models.
- Includes measurements of two key chemical parameters: total alkalinity and dissolved inorganic carbon concentration.
- Data files are available in multiple formats including XLSX, PNG, HTML, and PDF.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
