The Australian Ocean Data Network (AODN) is an interoperable online network of marine and climate data resources. AODN dataset collections cover a large geographic area, a wide range of observed parameters (physical, chemical, biological) and are obtained using a variety of platforms. The end users include researchers, students, managers, policy makers, consultants and fishers. All data products contributed to the AODN are made freely and openly available to the public via the AODN Portal ( ).

The GeoNetwork Opensource software is utilised in all of the AODN’s metadata catalogues, and is a major component of the infrastructure underpinning the AODN Portal.  It enables the management of ISO 19115 metadata records using controlled vocabularies and including links to specific map and download services.

The AODN team, as part of their 2019/2020 implementation plan, have committed to migrating their current GeoNetwork metadata catalogues to the latest stable release (3.10.2), and transitioning the metadata from the Marine Community Profile (MCP) 1.4/2.0 to the new ISO 19115-3:2018 standard.

To enable a smooth transition to the ISO 19115-3:2018 standard, a working group under the auspices of the AODN Technical Advisory Group was formed and met regularly over the past year to discuss and agree on the necessary mapping.

The transition to the new standard will provide long term benefits to the marine community such as leveraging wider support for the core standard, reduce the effort required to support and maintain specific tooling and facilitate the integration of dataset collections by contributors to the AODN.


Natalia Atkins graduated with a PhD in Zoology in 2007, and joined Australia’s Integrated Marine Observing System (IMOS)  in 2011. As part of the Australian Ocean Data Network (AODN) team, her primary role is in the creation and management of metadata. She also manages the AODN’s controlled vocabularies, and assists researchers and organisations in the submission of data and metadata to the AODN.
