Collecting and analysing Argo Float data

Using Google Earth you can follow the path of any Argo Float and learn about what is happening in the oceans.

Searching for Argo Floats

You can see every Argo Float on ‘Google Earth’ and follow the path of any selected Argo Float.

Below: by clicking on the small graphs you can see a temperature and salinity profile for that location in more detail.

What is happening here? Salinity falls rapidly from 35.5 to 34.4 but then stays at 34.4. before rising to 34.6.

What is happening here? Temperature falls rapidly from 19 degrees at the surface to 4 degrees and then more slowly to 2.5 degrees at the deepestAn Argo Flat profile showing changing temperature with depth

A profile showing changing temperature with depth underwater. You can see that the water in the top layer (1,000m) cools quickly with depth. Below that the temperature changes very slowly with depth. The top layer is called a thermocline. Image source
