Ocean observing has been in the news in recent days. A major international study published in the journal Science shows that the ocean is warming faster than we thought. It has several implications, including on the projected rate of sea level rise.
This discovery was based on radical improvement in the availability of sub-surface observations via the global ‘Argo’ network of autonomous, profiling floats. There are 4,000 Argo floats measuring the global ocean from the surface to a depth of 2 kilometres, all day, every day.
The IMOS Argo Australia Facility (operated by CSIRO) manages 400 floats in the Australian region, or 10% of the global network.
This is a significant contribution by our nation to international monitoring of the global ocean. It is an even more significant benefit to our nation. Australian scientists, students, policy-makers, managers, and marine industries have open access to ocean information from the entire global network (4,000 floats), and the modelling and analysis products that it produces.
