RV Investigator Voyage IN2015_V02: Underway Ocean and Atmospheric Measurements

Underway data recorded at 5-second intervals from the RV Investigator's second research voyage in May 2015, traveling from Sydney to Brisbane. 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

• Modeling ocean-atmosphere carbon flux based on pCO2 and atmospheric trace gas measurements.
• Analyzing ship navigation and ocean current patterns based on GPS, speed, and heading data.
• Studying phytoplankton distribution via fluorescence data mentioned in the thermosalinograph record.
• Investigating meteorological conditions over the ocean using wind, humidity, and radiation measurements.

Strengths

• Data recorded at a high temporal resolution of 5-second intervals.
• Includes three distinct data streams: navigation, water properties, and atmospheric conditions.
• Coverage of a specific research voyage from May 15 to 26, 2015.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
