AUV System Spec Sheet

Spray Glider platform

Manufacturer: Bluefin Robotics


The Spray Glider is manufactured by Bluefin Robotics who licensed the technology in 2004 from Scripps Oceanographic Institute

This buoyancy-driven underwater glider autonomously profiles the water column in a specified region, over deployment periods as long as 6 months. Spray changes its displacement using a hydraulic pump, enabling it to glide up and down along a see-saw glide path at descent (ascent) angles that can exceed 20 degrees.

In 1,500-meter-deep water, Spray can conduct over 800 profiles while traveling 4,000 kilometers across the sea bed.
Spray’s light weight (only 52 kilos) enables launch and recovery from small boats.
