Real-Time Ocean Temperature Profiles From Australian Ship Transits

Real-time temperature and depth profiles are collected using Expendable Bathythermographs (XBTs) deployed from commercial ships along established transit lines. The data undergoes scientific quality control by CSIRO scientists to identify oceanic features like eddies and fronts before global distribution. The dataset covers waters around Australia and across to New Zealand.

Use Cases

• Analyzing vertical temperature profiles to identify and track oceanic eddies and thermal fronts.
• Monitoring real-time sea surface temperature and subsurface thermal structure for climate and weather forecasting models.
• Studying temperature inversions and water column stability across major shipping routes in the Australian region.
• Calibrating satellite-derived sea surface temperature data with in-situ XBT profile measurements.

Strengths

• Data undergoes a full scientific QC process flagging bad data and identifying oceanic features.
• Real-time data transmission via Iridium SBD and insertion onto the Global Telecommunication System (GTS).
• Global distribution through the GTSPP data acquisition center ensures broad accessibility.

Limitations

• Spatial coverage is limited to established commercial ship transit lines, creating data gaps between routes.
• Sample data and specific row counts, column details, and temporal range are not provided in the input.
• Primary file formats listed (PDF, PNG, HTML) suggest metadata or visualizations, not the core scientific data files (NetCDF).
