The Australian National Data Service (ANDS), Nectar and Research Data Service (RDS), through their alignment, have engaged domains like the Integrated Marine Observing System (IMOS) in the Research Data Cloud (RDC) Program to establish strategic partnerships between research communities, data holders, data infrastructure operators and developers. One focus of the Marine RDC Project is to formalise linkage processes between major data custodians, demonstrate these linkages with pilot data services, and consolidate access to all important data collections.
The Australian Institute of Marine Science (AIMS) is one major marine data custodian. AIMS collect, describe, serve and maintain a database of Temperature Logger data that contains 130 million water temperature observations spread over 20-years, at 30 minute intervals, in over 800 locations across tropical Australia. It is a key dataset with existing public access through a custom web interface with significant uptake and re-use. The objective is to grow the data holdings available in the Australian Ocean Data Network (AODN) Portal by including this data collection, managed by AIMS. This allows users of the AODN Portal to visualise and download this dataset without noticing it is powered by web services operated by AIMS and not through a copy of the dataset on the AODN infrastructure.
AODN staff have assisted the AIMS Data Centre developers to improve the required services to publish this dataset on the AODN Portal. The improvements include the use of controlled vocabularies in the ISO 19115 metadata record describing the collection, a Web Map Service (WMS) and relevant filters to enable the display and subset of the data on the AODN Portal and a data download service using a Web Feature Service (WFS).
AIMS utilised infrastructure on the Amazon Web Services (AWS) platform to put in place a database and data ingestion process as well as compatible components to allow integration with the AODN Portal. New data are added automatically after calibration and initial quality control processes are completed. The system has offered a reliable and cost effective way to provide open access to this dataset.
The data is obtained from in situ data loggers deployed at numerous sites on the Great Barrier Reef, in the Coral Sea, North West Western Australia, regional ports in Queensland, Solitary Island, Papua New Guinea and the Cocos (Keeling) Islands. The loggers are exchanged approximately every 12 months at which point the data is uploaded into an internal data management system. Temperature loggers deployed on the reef-flat are placed below the Lowest Astronomical Tide level, that is, the lowest tide level that can be predicted to occur under average meteorological conditions and under any combination of astronomical conditions.
To discover the AIMS Temperature Logger data on the AODN Portal select "Australian Institute of Marine Science (AIMS)" from the Organisation facet in Step 1, this narrows down the many pages of results that are found on the AODN Portal to only 2 pages. A Keyword search of “logger” will narrow the results even further, then, simply "select" the AIMS Sea Temperature Observing System (AIMS Temperature Logger Program) collection to add it to the map.
