RV Investigator Underway Ocean and Atmospheric Data from June 2018 Voyage

Underway data from the RV Investigator voyage IN2018_E01, which took place between June 9 and June 11, 2018, departing from and arriving in Hobart, Tasmania. The data is collected by the Marine National Facility and includes navigation, thermosalinograph, and atmospheric measurements. This unprocessed data is supplied to the Australian Ocean Data Network and used by organizations like NOAA and the Bureau of Meteorology for satellite validation and weather modeling.

Use Cases

• Validate satellite-derived sea surface temperature (SST) products based on the SBE 38 SST sensor data.
• Study air-sea flux dynamics using the suite of atmospheric measurements, including wind, radiation, and trace gases.
• Analyze ocean water properties and biogeochemistry using thermosalinograph data for salinity, temperature, fluorescence, and pCO2.
• Calibrate and test oceanographic instruments, as the voyage was designated for Sea Acceptance Testing & Calibrations.

Strengths

• Data is integrated into major global data products, including ICOADS R3.0, ERSST.v4, and HadSST3, indicating a level of quality and trust.
• Describes a specific, continuous data collection period from June 9 to June 11, 2018.
• Atmospheric and SST data are disseminated in real-time via the Global Telecommunications System (GTS) for operational use.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data is described as 'unprocessed', which may require significant cleaning and calibration for research use.
