The TAO TRITON array is a network of buoys spread across the equatorial Pacific to monitor the subsurface ocean and surface meteorology of the ocean.

The TAO (Tropical Atmosphere Ocean) array was initiated in 1984 by the Pacific Marine Environment Laboratory (PMEL) in the USA.  In 2000, contributions from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) was officially included in the array title, so it is now referred to as the TAO-TRITON array.

In 1984, the ATLAS (Autonomous Temperature Line Acquisition System) buoy was developed (see picture).  Over the next 10 years, more buoys were added to the network during the Tropical Ocean Global Atmosphere (TOGA) project, until the array reached it's proposed design in 1994.

Real Time data from the array is freely available from the TAO website,

An example of the data from the past 5 days, and a comparison of data form the previous year is given below.
