RV Investigator IN2018_V01 Underway Oceanographic and Atmospheric Data, 5-Second Intervals

Continuous 5-second interval data from the RV Investigator voyage IN2018_V01, collected between January 11 and February 21, 2018, sailing from and to Hobart, Tasmania. The Marine National Facility voyage aimed to detect Southern Ocean change through repeat hydrography, deep Argo floats, and trace element biogeochemistry. Data are processed and archived by the CSIRO Oceans & Atmosphere Information and Data Centre in Hobart.

Use Cases

• Modeling ocean-atmosphere carbon exchange based on pCO2 and atmospheric trace gas measurements.
• Analyzing phytoplankton dynamics based on fluorescence and photosynthetically active radiation (PAR) data.
• Studying Southern Ocean water mass properties based on thermosalinograph (TSG) salinity and temperature data.
• Validating satellite-derived sea surface temperature using in-situ radiometer measurements.
• Tracking vessel navigation and ocean currents based on GPS, gyro, and Doppler log data.

Strengths

• Data recorded at high temporal resolution of 5-second intervals.
• Covers a multi-disciplinary suite of over 20 oceanographic and atmospheric variables.
• Voyage had a specific scientific objective focused on detecting Southern Ocean change.
• Data are available in processed formats (NetCDF and CSV) at 5-second, 10-second, and 5-minute intervals.

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 and temporal bias inherent to a single 2018 voyage in the Southern Ocean.
