RV Investigator Voyage IN2015_V02: Underway Ocean and Atmospheric Data

May 15-26, 2015 data collected from the Marine National Facility RV Investigator voyage between Sydney and Brisbane. The dataset includes continuous 5-second interval measurements of navigation, water properties, and atmospheric conditions. It is processed and archived by the CSIRO Oceans & Atmosphere Data Centre in Hobart.

Use Cases

• Modeling ocean-atmosphere carbon flux based on pCO2 and atmospheric trace gas measurements.
• Analyzing mesoscale oceanographic features based on high-frequency salinity and temperature data.
• Studying wind patterns and air-sea interaction based on ultrasonic wind speed and direction data.
• Calibrating satellite-derived sea surface data based on in-situ radiometer and pyranometer readings.

Strengths

• Data recorded at a high temporal resolution of 5-second intervals.
• Includes a multi-faceted suite of measurements covering navigation, water column, and atmospheric variables.
• Data is available in multiple formats (NetCDF and ASCII) and aggregated intervals (5 sec, 10 sec, 5 min).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single 12-day voyage in the Tasman Sea.
