| Summary: | Statement: XBT data is collected from the volunteer observing ships and returned to CMAR. We then convert the data into our netcdf format and perform quality control on temperature, rejecting data that shows sign of instrument faults or other anomalies that are not considered 'real'. Any real features of the profile are flagged as well and these flags can be used to study the occurrence of such features (inversions, fine structure, 'steps', etc). The quality control system is based on Matlab and called Mquest. Credit Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.

Expendable Bathythermographs (XBTs) have been used for many years by oceanographers to measure the temperature of the upper ocean. These instruments are simple devices which are designed to be deployed from moving vessels, enabling broad scale coverage of the world's oceans.
