The National Mooring Network facility comprises a series of national reference stations and regional moorings designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The Deep Water Moorings facility (formerly known as the Australian Bluewater Observing System) provides the coordination of national efforts in the sustained observation of open ocean properties with particular emphasis on observations important to climate and carbon cycle studies, with selected moorings from its Deep Water Arrays sub-facility providing data to this collection. This collection represents the hourly aggregated time-series product, which combines selected variables measured by all the instruments deployed at a site, binning the values into a fixed one-hour interval. Only good-quality measurements (according to the automated quality-control procedures applied by the National Mooring Network) are included. The parameters are: temperature, salinity, dissolved oxygen, chlorophyll estimates, turbidity, down-welling photosynthetic photon flux (PAR), and current velocity, accompanied by depth and pressure when available. The observations were made using a range of temperature loggers, conductivity-temperature-depth (CTD) instruments, water-quality monitors (WQM), acoustic Doppler current profilers (ADCPs), and single-point current meters.Maintenance and Update Frequency: continualStatement: Each of the aggregated variables are produced by selecting only the data flagged ?good? or ?probably good? in the input files, binning to a one-hour interval, and concatenating the resulting values into a single file. Out-of-water measurements are also excluded. The quality control flags themselves are not included in the output file. The method used to calculate the binned values depends on the parameter. For depth, pressure, temperature, salinity, oxygen, and current velocity components, the values in each bin are averaged. For chlorophyll, turbidity, and photosynthetic photon flux, a median is used. For each variable, statistical measures of each bin (minimum, maximum, standard deviation, and number of observations) are also provided. Timestamps in the input files indicate the start of each measurement window, which varies in duration by instrument and deployment, and can be up to an hour long. Because this duration is not consistently documented in all input files, timestamps have not been shifted to the centre of the window before binning. This could lead to an artificial shift of up to half an hour in the product data. The size of this shift, where known, has been recorded in the product file. Instrument details and references to the input files are stored as variables in order to record the provenance of each measurement.

Brief description

Integrated Marine Observing System (IMOS) have moorings across both it's National Mooring Network and Deep Water Moorings facilities. The National Mooring Network facility comprises a series of national reference stations and regional moorings designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The Deep Water Moorings facility (formerly known as the Australian Bluewater Observing System) provides the coordination of national efforts in the sustained observation of open ocean properties with particular emphasis on observations important to climate and carbon cycle studies, with selected moorings from its Deep Water Arrays sub-facility providing data to this collection.
This collection represents the hourly aggregated time-series product, which combines selected variables measured by all the instruments deployed at a site, binning the values into a fixed one-hour interval. Only good-quality measurements (according to the automated quality-control procedures applied by the National Mooring Network) are included.
The parameters are: temperature, salinity, dissolved oxygen, chlorophyll estimates, turbidity, down-welling photosynthetic photon flux (PAR), and current velocity, accompanied by depth and pressure when available. The observations were made using a range of temperature loggers, conductivity-temperature-depth (CTD) instruments, water-quality monitors (WQM), acoustic Doppler current profilers (ADCPs), and single-point current meters.
