Toolbox for Secondary Quality Control on Ocean Chemistry and Hydrographic Data

A MatLab toolbox for performing secondary quality control on oceanographic data via crossover analysis. The toolbox is developed by the National Oceanic and Atmospheric Administration for sea-going scientists to assess measurement bias during expeditions. It is described in detail and is intended for use with high-quality reference measurements of seawater properties.

Use Cases

• Assessing measurement bias during oceanographic expeditions based on the described crossover analysis method
• Performing post-cruise data adjustment to ensure consistency with historical regional measurements
• Validating oceanographic models based on high-quality reference measurements of seawater properties
• Quantifying spatial and temporal variability in ocean chemistry based on bias-corrected data

Strengths

• Toolbox is designed for immediate use during expeditions to allow for timely data correction
• Methodology for secondary quality control via crossover analysis is described in detail
• Developed by the National Oceanic and Atmospheric Administration, a recognized authority

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data format is HTML, which may require extraction or conversion for analysis
