The primary access to IMOS data is through the AODN Portal. From here, you can download whole data collections or temporal and/or spatial subsets of these collections, together with the metadata describing the collection. Metadata is also available from the IMOS metadata catalogue.
All IMOS data are accessible through this file server.
Information on netCDF conventions can be found in the IMOS netCDF Convention 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.
For more information on contributing to the AODN see the Portal User Guide - Contributing Data Section.
