Eight water mass contributions and remineralization estimates derived from 2018 Southern Ocean CTD data. This dataset contains input parameters like temperature, salinity, and nutrients, and output parameters from an extended optimum multiparameter analysis. Data is provided by the Australian Ocean Data Network and is referenced to depth and geographical position.
Use Cases
- Modeling water mass mixing and transformation based on proportional contributions of 8 defined water masses.
- Estimating biological remineralization in the ocean based on the output Delta-O parameter.
- Analyzing relationships between physical (temperature, salinity) and chemical (oxygen, nitrate) ocean parameters.
- Studying Southern Ocean regional oceanography using the parameterization and end-members defined in the cited methodology.
Strengths
- Data is geospatially and depth-referenced, providing latitude, longitude, and depth for each observation.
- Methodology is documented with references to Pardo et al. (2017) and Traill et al. (2023), including robustness and uncertainty analyses.
- Includes both input (6 physical/chemical parameters) and output (8 water mass contributions + Delta-O) data for a complete analysis workflow.
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 the single 2018 SR3 occupation cruise.
Provenance
- Source
