RV Investigator IN2015_V02 Underway Ocean and Atmospheric Data

Underway data from the RV Investigator voyage IN2015_V02, recorded at 5-second intervals from May 15 to May 26, 2015. The dataset includes navigation, thermosalinograph, and atmospheric measurements collected by the CSIRO Oceans & Atmosphere Data Centre. Data is available in NetCDF and ASCII formats.

Use Cases

• Track vessel navigation and ocean currents based on GPS, speed, and heading data.
• Analyze seawater properties like salinity and temperature from thermosalinograph (TSG) measurements.
• Study atmospheric conditions and air-sea gas exchange using wind, humidity, and trace gas data.
• Calibrate satellite ocean color data using in-situ fluorescence measurements.

Strengths

• Data recorded at a high temporal resolution of 5-second intervals.
• Includes a multi-parameter suite covering navigation, ocean water, and atmospheric variables.
• Voyage time range (May 15-26, 2015) and geographic track (Sydney to Brisbane) are explicitly stated.

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 a single 12-day voyage.
