Exploring the deepest underwater caves on Earth...

The Deep Phreatic Thermal Explorer (DEPTHX) project is creating the autonomy needed to enable an underwater robot to map three-dimensional spaces like flooded caverns and mines.

Together with our partners we are creating a vehicle that will first explore the depths of the Zacatón Cenote in central Mexico. This scientific investigation is seeking to understand the unique organisms that survive in this, the deepest flooded sink hole in the world.
