Seaglider data from the oceans around Australia have been collected by the Ocean Gliders Facility (formerly known as the Australian National Facility for Ocean Gliders (ANFOG)), since February 2009 and are ongoing. The data are obtained from an onboard suite of instruments which include Seabird-SBE41 CTD (Conductivity, Temperature, Depth), WETLabs BBFL2VMT 3 parameter optical sensor (measuring Chlorophyll-a, CDOM and 650nm Backscatter) and a Seabird-SBE43 dissolved oxygen sensor.Statement: The data has undergone the following quality control tests: 1) Impossible date test, which checks if time values are within a timeframe possible for the fleet; 2) Impossible location test, which requires that the observation latitude and longitude from the float be sensible; 3) Range test, which applies a gross filter on observed values for the measured scientific parameters, that accommodates all of the expected extremes encountered in the oceans around Australia; 4) Deepest pressure test, which requires that the profile has pressures/depths that are not higher than vehicle safe depth range plus 10%. (If there is a region of incorrect pressures, all corresponding measurements are also flagged as bad data.) 5) Spike test, which considers that the difference between sequential measurements where one measurement is quite different than adjacent ones, is a spike in both size and gradient. The test does not consider the differences in depth, but assumes a sampling that adequately reproduces the temperature and salinity changes with depth. The algorithm is used on temperature and salinity profiles only. 6) Gradient test, which is failed when the difference between vertically adjacent measurements is too steep. The test does not consider the differences in depth, but assumes a sampling that adequately reproduces the temperature and salinity changes with depth. The algorithm is used on temperature and salinity profiles only. The results of the above mentioned tests are listed using an IMOS standard set of IODE flags, which the user should refer to when using the data. Only items flagged as 1: Good data or 8: Interpolated data should be used. Each parameter's quality flagging is found in its corresponding quality control parameter (e.g. for the parameter PSAL, the quality flags are found in PSAL_quality_control).

Brief description

The dataset contains temperature, salinity and biological parameters including dissolved oxygen and turbidity data measured by a Seaglider off Bicheno (Tasmania). Seaglider data from the oceans around Australia have been collected by the Ocean Gliders Facility (formerly known as the Australian National Facility for Ocean Gliders (ANFOG)), since February 2009 and are ongoing. The data are obtained from an onboard suite of instruments which include Seabird-SBE41 CTD (Conductivity, Temperature, Depth), WETLabs BBFL2VMT 3 parameter optical sensor (measuring Chlorophyll-a, CDOM and 650nm Backscatter) and a Seabird-SBE43 dissolved oxygen sensor.
