RV Investigator Underway Ocean and Atmospheric Data from 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 includes continuous navigation, thermosalinograph, and atmospheric measurements. The record is provided by the Australian Ocean Data Network.

Use Cases

• Validate satellite sea surface temperature (SST) products based on in-situ SBE 38 SST data.
• Study air-sea fluxes for climate research based on meteorological data uploaded to the SAMOS project.
• Assimilate real-time SST and atmospheric data into numerical weather prediction models.
• Analyze ocean water properties like salinity and fluorescence based on thermosalinograph (TSG) measurements.

Strengths

• Data is integrated into major global climate data products, including ICOADS R3.0, ERSST.v4, and HadSST3.
• Voyage dates and departure/arrival location (Hobart, June 9-11, 2018) are explicitly stated.
• Data is disseminated in real-time via the Global Telecommunications System (GTS) for operational use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
