The ACCESS Ocean Model (ACCESS-OM) is a global coupled ocean model that includes ocean, ocean biogeochemistry, and sea ice components, linked together by a coupler.
The atmospheric fields that drive the model are provided by a data source, usually derived from reanalysis.


ACCESS-OM2 1 is a suite of coupled ocean-sea ice models developed by the Consortium for Ocean-Sea Ice Modelling in Australia (COSIMA).

The ACCESS-OM2 has versions at three different spatial resolutions: ACCESS-OM2, ACCESS-OM2-025 and ACCESS-OM2-01.
