    The Australian Bluewater Observing System (ABOS) Facility 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. This collection contains time-series observations of temperature and salinity from moorings deployed by the ABOS Air-Sea Flux Stations (ASFS) and Deepwater Arrays (DA) sub-facilities. The primary parameters are temperature, pressure (when available) and depth of the instrument. A subset of this collection also includes conductivity and salinity. The observations were made using a range of temperature loggers, conductivity-temperature-depth (CTD) instruments, and temperature sensors on acoustic Doppler current profilers (ADCPs).

    This product is based on Vaisala RS92 radiosonde measurements of temperature, humidity, wind and pressure that have been processed following the requirements of the GCOS Reference Upper Air Network (GRUAN) that were described in Immler et al. [2010]. The GRUAN data product file comply to the requirements of GRUAN in particular by providing a full uncertainty analysis. The uncertainty is calculated according to the recommendations of the “Guide for expressing uncertainty in measurement” [GUM2008]. The total uncertainty is assessed from estimates of the calibration uncertainty, the uncertainty of corrections and statistical standard deviations. Corrections are applied such that the data is bias free according to current knowledge.

    This dataset contains Sea Surface Temperature (SST) underway observations collected on trips of a merchant vessel (MV Highland Chief - VROB) between south-east of Australia (Melbourne) and Papua New Guinea, including New Zealand, New Caledonia and Solomon Islands. The data have been quality controlled by the Bureau of Meteorology. Enhancement of Measurements on Ships of Opportunity (SOOP)-Sea Surface Temperature (SST) aims to supply near real-time SST data (within 24 hours) from SOOPs and research vessels in the Australian region.

    Manly Hydraulics Laboratory (MHL) part of the NSW Office of Environment and Heritage (OEH) operates a system of Waverider buoys off the NSW coastline. The buoys measure wave height and other wave statistics such as wave period on a continuous real-time basis, and are also capable of measuring wave direction (wave data accessible via related metadata record) and sea surface temperature (SST). The data is gathered by the Waverider system developed by the Dutch company, Datawell, namely thermistors that are mounted inside the hull of the buoys, at the base of the buoy about 0.5m below the water surface. The SST data is stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email.

    Manly Hydraulics Laboratory (MHL) part of the NSW Office of Environment and Heritage (OEH) operates a system of Waverider buoys off the NSW coastline. The buoys measure wave height and other wave statistics such as wave period on a continuous real-time basis. Some of the buoys are also capable of measuring wave direction and sea surface temperature (discoverable in a separate collection). This metadata record is a parent record describing the MHL Waverider system as a whole. The child metadata records describe each deployment of the buoy in more detail with links to downloadable data. The data is gathered by the Waverider system developed by the Dutch company, Datawell. The Waverider system uses an accelerometer mounted in a loose tethered buoy (0.7 or 0.9m in diameter) to measure the vertical accelerations of the buoy as it moves with the water surface. The accelerations are integrated twice within the buoy and the displacement signal so obtained is then transmitted to a shore station where it is processed to provide wave data statistics. The wave data is stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email. The wave direction capable Waverider buoys utilise a heave-pitch-roll sensor, two fixed X and Y accelerometers and a three axis fluxgate compass to measure both vertical and horizontal motion. An on-board processor converts the buoy motion to three orthogonal (vertical, north-south, east-west) translation signals that are transmitted to the shore station.

    The Australian Bluewater Observing System (ABOS) Facility 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. This collection contains time-series observations of current velocity from moorings deployed by ABOS. The primary parameters are the zonal, meridional and vertical components of the current speed within different bins in the water column, the height above the instrument of each bin, the pressure (when available) and depth at the instrument. Temperature at the instrument is also usually measured. The observations were made using a range of Acoustic Doppler Current Profiler (ADCP) and Acoustic Doppler Current Meter (single point measurement) instruments. This ABOS dataset includes discrete locations south of Tasmania, off Queensland and Indonesia.

    This dataset contains Sea Surface Temperature (SST) underway observations collected on trips of a merchant vessel (MV Portland - VNAH ) between Fremantle (Western Australia) and Melbourne (Victoria). The data have been quality controlled by the Bureau of Meteorology. Enhancement of Measurements on Ships of Opportunity (SOOP)-Sea Surface Temperature (SST) aims to supply near real-time SST data (within 24 hours) from SOOPs and research vessels in the Australian region.

    The Australian National Mooring Network Facility is a series of national reference stations and regional moorings designed to monitor particular oceanographic phenomena in Australian coastal ocean waters. The Water Quality Meters (WQMs) collect time series of physical and 'biogeochemical' data: temperature, pressure, salinity, conductivity, depth, dissolved oxygen, chlorophyll, turbidity and fluorescence. The WQMs and some NXIC CTDs at one or more depths collect bursting data and data from the bursts have been cleaned and averaged to create data products. The series of National Reference Stations (NRS) and several regional stations from the "Queensland and Northern Australia" and "New South Wales" ANMN sub-facilities contribute data to produce the burst averaged data products presented here.
