Leeuwin Current Nitrate and Oxygen Layer Data from RV Investigator Voyage IN2019_V03

Data from the 2019-20 RV Investigator voyage IN2019_V03 investigating a high nitrate, low oxygen layer in the Leeuwin Current. The dataset includes CTD, ADCP, and Triaxus data, supported by Sea Surface Height satellite data and CSIRO Atlas of Regional Seas (CARS) data. MATLAB code for calculating rotated velocity and transport of the East Greenland Current is also provided.

Use Cases

• Modeling nitrate and oxygen transport based on Triaxus and CTD data mentioned in the description.
• Analyzing current velocity and volume transport using ADCP data and provided MATLAB code.
• Correlating in-situ oceanographic measurements with satellite-derived sea surface height data.
• Studying water mass properties and layering in the Leeuwin Current using the combined dataset.

Strengths

• Includes data from multiple oceanographic instruments (CTD, ADCP, Triaxus) for cross-validation.
• Supported by satellite altimetry and a regional climatology (CARS) for broader context.
• Provides MATLAB code for calculating key transport variables (volume, salinity, heat, oxygen).

Limitations

• Nitrate data from Triaxus is described as incomplete and pending upload.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
