Australian Antarctic Data Centre (AADC) Data Integration
For over thirty years now, the Australian Antarctic Division has been collecting underway data from vessels deployed to the Southern Ocean as part of the Australian Antarctic program. This underway data (which includes meteorological and oceanographic data) is archived in the Australian Antarctic Data Centre (AADC) and catalogued with metadata records – one per voyage as well as an overarching parent metadata record. These data have been available for download as CSV files for every voyage through AAD, but are now also available for visualisation and download as CSV via the Australian Ocean Data Network Portal.
Work to integrate the AADC Underway Data logger with the AODN Portal, was one of the components of the Australian Research Data Commons (ARDC) funded Marine Research Data Cloud (RDC) program. The underway data was targeted as it is a key dataset with existing public access and interest, and builds on the two AAD data collections already available in the AODN Portal. Staff from the AODN and AADC collaborated on this project, which mainly involved setting up of compliant software on AAD infrastructure.
CSIRO Data Integration
Another component of the Marine RDC program was to integrate the CSIRO data trawler with the AODN Portal. Two significant data collections are now discoverable on the AODN Portal.:
This data collection includes data collected since 1982, during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. CTD data usually includes conductivity, temperature, depth and salinity (derived), and may also include any or all of oxygen, fluorescence, optical back scatter (OBS), pH and transmittance.
This data collection includes data collected since 1942, during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels and coastal stations. Hydrology data usually consists of salinity and nutrient values obtained by analysing water samples taken at several depths at each station. The data may include temperature for some depths, nutrients may include any or all of ammonia, nitrite, phosphate, nitrate, silicate, oxygen.
The AODN thanks the staff at the AAD and CSIRO for assistance in making these collections available.
