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.Maintenance and Update Frequency: continualStatement: Hourly product These gridded products are created from IMOS FV01 individual moorings instrument files collected on the East Australian Current (EAC) moorings (6 moorings). Period of data collection is over 6 deployments from 2012-2022 (with the exception of approximately 2-year gap from 2013-2015 where no moorings were in place). The products at EAC0500 (500m mooring) also include data from the National Mooring Network, South East Queensland (SEQ) 400m coastal mooring. We have also created a product for the National Mooring Network, North Stradbroke Island (NSI) mooring which supports the EAC Deep Water Mooring array. Individual instrument files are screened to remove data flagged as 'bad' (flags 3 & 4). Temperature, salinity and velocity data is put onto a common time grid (hourly) and common depth grid (10m to 400m and 20m from 400m to bottom) using a linear interpolation, for each deployment. Deployments are concatenated together to give one time-continuous dataset for each mooring site. Periods where an instrument fails or data is missing is filled with missing values, and the final variables are TEMP, UCUR, VCUR and PSAL.Statement: Daily product These gridded products are created from IMOS FV01 individual moorings instrument files collected on the East Australian Current (EAC) moorings (6 moorings).

Full description

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.

Maintenance and Update Frequency: continual

Statement: Hourly product These gridded products are created from IMOS FV01 individual moorings instrument files collected on the East Australian Current (EAC) moorings (6 moorings). Period of data collection is over 6 deployments from 2012-2022 (with the exception of approximately 2-year gap from 2013-2015 where no moorings were in place). The products at EAC0500 (500m mooring) also include data from the National Mooring Network, South East Queensland (SEQ) 400m coastal mooring. We have also created a product for the National Mooring Network, North Stradbroke Island (NSI) mooring which supports the EAC Deep Water Mooring array. Individual instrument files are screened to remove data flagged as 'bad' (flags 3 & 4). Temperature, salinity and velocity data is put onto a common time grid (hourly) and common depth grid (10m to 400m and 20m from 400m to bottom) using a linear interpolation, for each deployment. Deployments are concatenated together to give one time-continuous dataset for each mooring site. Periods where an instrument fails or data is missing is filled with missing values, and the final variables are TEMP, UCUR, VCUR and PSAL.

Statement: Daily product These gridded products are created from IMOS FV01 individual moorings instrument files collected on the East Australian Current (EAC) moorings (6 moorings).

Periods where an instrument fails or data is missing is filled with missing values, and the final variables are TEMP, UCUR, VCUR and PSAL. Additional variables in the file are the '*_FILLED' variables (eg, 'TEMP_FILLED'), and these are created using a SOM (Self Organising Maps) neural network machine learning algorithm to fill the missing periods of data. The method is fully described in the data paper in the link section.
