Argo Float Makes One Millionth Profile

December 11, 2012

The worldwide Argo float array of over 3,000 devices made its one-millionth profile in the beginning of December.  Measuring temperature and salinity in the first 3,000 feet of the ocean, the Argo float array helps scientists better understand changes in ocean heat content and salinity. 

PMEL currently has 476 active Argo floats mostly in the Pacific Ocean, making up 13% of the worldwide array.  You can find out more about PMEL’s Argo floats and where they are located on their website.
