The Argo program was set up by a collaborative of research groups at the turn of the century in response to growing concerns about global climate change.
Named after Jason’s “Argo”, a ship in Greek Mythology that undertook the treacherous voyage to capture the Golden Fleece, this ambitious program involves the deployment of data-collecting floats in oceans across the world. They sink to depths of 1500m and only rise to transmit information in real time via a satellite which allows sea temperatures, salt levels (salinity) and ocean velocity to be monitored. There are currently over 3000 floats in circulation.
One of the most significant features about Argo data is that it is freely available to anyone (www.argo.net). The speed with which the information is recorded and published allows oceanographers to quickly draw seemingly conclusive analytical reports about trends and changes in our oceans.
However, the accessibility of the survey network can lead to problems. Information published has not always been accurate and science writers are quick to use Argo data to shape and support their theories, rather than allowing the data to collate over time to form more conclusive readings.
It is expected that in the not too distant future, the Argo global dataset will provide crucial indications that global warming is happening. Some feel that there is already enough evidence to support this theory and that we should take immediate action to combat its effects.
Let’s pretend for a moment that the people of the world have put their absolute faith in your hands. How would you use Argo data findings? Consider:
Can we really suggest global warming is occurring based on monitoring the oceans alone?
To get a truly conclusive indication that climate change is happening might take many more years of Argo data observation. Would you wait or take action now, potentially making decisions that will affect the lives of millions?
Would it be better if the data collected was less readily available, or do you feel that everyone has the right to such information?
The Argo float is in the Atmosphere Gallery, great for all age groups to explore the many issues concerning climate change in a balanced and engaging way.
