In the News: Argo Floats

In the Ocean, Clues to Change. (The New York Times, 8/11/2014)

Building a better robot.  That is where the prototype robotic floats, developed at the Scripps Institution of Oceanography, come in. 

The idea is to supplement the older robots that are already prowling the ocean. That system, known as Argo, is one of the scientific triumphs of the age, but even the most advanced of the floats can dive only a little more than a mile, so they miss the bottom half of the sea. 

Developing robots able to go deeper has been a technical challenge, but scientists think they are about to lick it...

Argo floats....
  • can rise or sink by themselves
  • powered by batteries and can last for 4-7 years
  • float for 9 days,  measuring temperature and current speed
  • sinks to 2,000 meters on day 9
  • rises slowly to surface on day 10 measuring temperature, saltiness, and depth
  • sends data to satellite
  • repeats cycle every 10 days

How is Argo data used?
  • Farmers.  Better predict weather and climate.
  • Oil and gas industries.  Information about waves and swell
  • Shipping industries.  Current speed and direction.
  • Fishing industries.  Finding schools of fish.
  • Scientists.  Understand the oceans and global climate.
