Statement: The Argo data system has three levels of quality control. The first level is the real-time system that performs a set of agreed, automated, checks on all float measurements. The real time quality control procedures are described in the Argo Quality Control Manual, available from the Argo Information Centre (http://wo.jcommops.org/cgi-bin/WebObjects/Argo). Quality flags are: 0 - no quality control done 1 - good data 2 - good data with some suspicious features 3 - bad data that are potentially correctable 4 - bad data that is not correctable The second level of quality control is done in delayed mode, after the profiles are more than 6 months old. Profiles undergo rigorous semi-automated and manually supervised tests to detect and correct drift in salinity and to detect drift in pressure. To accurately detect these drifts, 6 months of data is required. These procedures are also described in the Argo quality control manual. 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. Credit CSIRO Oceans & Atmosphere Credit Bureau of Meteorology (BOM) Credit Royal Australian Navy (RAN) Argo Australia aims to undertake real time monitoring of the broad ocean state around Australia by maintaining an array of profiling (Argo) floats that measure temperature, salinity and pressure down to 2000m every 10 days in real time. The data presented here, represent all Australian Argo profiles collected since 2000, and covers the oceans in the southern hemisphere worldwide. A typical Argo float mission is to profile from 2000 m depth to the sea surface every 10 days. On deployment, the float sinks to a depth of 1000 m and drifts with the ocean currents for 9 days. Then the float sinks deeper to its profile depth (usually 2000 m) before starting to ascend through the water column measuring ...
