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 studies.
This collection has both hourly- and daily depth-gridded products with currents, temperature and salinity (one file per mooring). The products are created from individual instrument files collected during six 18-month deployments in the East Australian Current (EAC) off Brisbane, Australia. The collection also includes a product for the National Mooring Network's North Stradbroke Island site, and the products at EAC0500 (500m mooring) also include data from the South East Queensland (SEQ) 400m coastal mooring. The data can be used for time series analysis of individual moorings in the EAC deployments.
The observations were made using a range of temperature loggers, conductivity-temperature-depth (CTD) instruments and acoustic Doppler current profilers (ADCPs). The data has been interpolated to one-hourly intervals (hourly product) and daily intervals (daily product), and to a fixed set of target depths (both products) for each IMOS EAC mooring site. Only good-quality measurements (after application of quality control flags using the IMOS toolbox and as described in the quality control reports for each deployment) are included.
This product is independent of the IMOS - Moorings - Gridded time-series product (https://catalogue-imos.aodn.org.au:443/geonetwork/srv/api/records/279a50e3-21a5-4590-85a0-71f963efab82), which is produced from binned data (in time), and utilises all temperature records including ADCP temperatures. The CSIRO gridded product uses only high quality temperature from the Seabird and temperature logger instruments. In addition, where current observations overlap in depth, the data is selected based on a set of criteria as specified in the product documentation.
