The USC researchers have proposed water on Mars exists within the scope of a broader geographical area than previously thought.
If confirmed, an active system of water some 2,460ft (750m) underground could be forcing water to the surface.
Study co-author Abotalib Z Abotalib, a postdoctoral research associate at USC, noted similar behaviour of water systems in the aridest regions on Earth.
He said: “We have seen the same mechanisms in the North African Sahara and in the Arabian Peninsula, and it helped us explore the same mechanism on Mars.”
