An arr... what?!
Argo Floats measure the temperature and salinity (salt and other chemicals) in our oceans. They float around the ocean about 1000m (1km) below sea level for 9 days at a time before sinking to 2000m (2km) and recording the temperature and salinity in a water column up to the surface. This takes about 10 hours to record. The Argo Float then sends the data it has collected to a satellite before sinking back down to 1000m for another 9 days.
There are over 3000 of them in our ocean. Click on the Map for a larger view. Source : wikipedia
