Bluelink has provided for the development and deployment of two regional modelling systems: the Relocatable Ocean Atmosphere Model (ROAM).
Relocatable Ocean Atmosphere Model (ROAM)
The Relocatable Ocean and Atmospheric Model (ROAM) is a tactical tool, initially developed for the Royal Australian Navy, to improve prediction of sonar range in the ocean and radar in the atmosphere.
Using an intuitive and accessible user interface (Fig. 1), ROAM enables an operator to configure an ocean, atmospheric, and/or wave model for any region around Australia to produce a hindcast, over any time period, of a three to seven day forecast.
An example of comparisons between observed and predicted sea-level off Fremantle is shown in Fig. 2 for an case when Fremantle experienced the highest sea-level on record. The model results presented were produced soon after the event. The results show that the automatically configured model reproduces the key features of the circulation, including an interesting resonance after the peak in sea-level.
ROAM accesses information from the Bluelink operational ocean forecast system – OceanMAPS – and the Bureau of Meteorology`s operational numerical weather prediction system to initialse and force each forecast.

Bluelink was established in 2001, as a partnership between CSIRO, Bureau of Meteorology, and the Royal Australian Navy, with the goal of developing an operational forecasting system for the global ocean circulation around Australia.
The Bluelink research team continues to develop forecasting capabilities for ocean circulation on scales ranging from global eddy-scales, regional shelf-scales and littoral beach-scales, for the benefit of the Australian community.
