They were mostly lost to space early in Mars’s history, in processes driven by the Sun’s UV photons and solar wind after Mars lost its magnetic field. 


Atmospheric Loss to Space and the History of Water on Mars
Mars is the nearest planet that potentially harbors life and that can be explored by humans, so its history of water is of considerable importance. Water was abundant on early Mars but disappeared ...
Special Issue: Water on Mars
Mars is cold enough that its meager water content appears to exist today simply in frozen and gas phases. But as recent evidence suggests, that may not have always been the case.
Martian water loss to space enhanced by regional dust storms
Mars has lost most of its initial water to space as atomic hydrogen and oxygen. Spacecraft measurements have determined that present-day hydrogen escape undergoes large variations with season that

The Climate of Early Mars
The nature of the early martian climate is one of the major unanswered questions of planetary science. Key challenges remain, but a new wave of orbital and in situ observations and improvements in
A Habitable Fluvio-Lacustrine Environment at Yellowknife Bay, Gale Crater, Mars
The Curiosity rover discovered fine-grained sedimentary rocks, which are inferred to represent an ancient lake and preserve evidence of an environment that would have been suited to support a martian
