About Spray2™

The Spray2^™ is the only commercially available version of the Scripps Institution of Oceanography’s (SIO) Spray2 glider, a next-generation autonomous underwater glider. Spray2™ improves on its predecessor, the Spray glider, via enhanced performance (endurance, range, speed), simpler sensor servicing and integration, larger payload volume with improved connection options, and removable wings and tailfin for easy shipment and field operations.
