Your main access to marine and climate data is through the AODN Portal.
Marine data and information are the main products of the AODN. AODN staff provide a framework for data and information management that allows discovery and access of the data by scientists, managers and the public. The Portal incorporates a catalogue of metadata, a search interface driven by facets utilising controlled vocabulary terms, and a map interface that can be used to interact with AODN datasets and offers data download in a number of formats.
For hints, tips and tricks on finding, sub-setting and downloading data head over to the Portal User Guide!
The AODN Maintains a list of useful links to organisations and/or websites that can provide more information specific to data tools, national/international collaborators or related infrastructure.
