This dataset contains Sea Surface Temperature (SST) underway observations collected on trips of a merchant vessel Xutra Bhum (callsign HSB3402). This data stream has now been discontinued (April 2013).
Bulk SST is measured by SBE48 hull contact sensor. The sensor is installed in the bow thruster room at 8.5m depth.
Observed data are 1-minute median SST values and are retrieved from the vessel once an hour and quality controlled at the Bureau of Meteorology. A daily file is available after 0100 UTC. High-resolution 1-minute median data are available in the delayed mode approximately every 3 months.
