An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [1] The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the ...
The implication here is that a great northern ocean may have existed for millions of years. One argument against an ocean has been the lack of shoreline features. These features may have been washed away by these tsunami events. The parts of Mars studied in this research are Chryse Planitia and northwestern Arabia Terra. These tsunamis affected ...
The Mars ocean theory suggests that nearly a third of the surface of Mars was once covered by water, though the water on Mars is no longer oceanic. Much of it now resides in the ice caps, in a solid state. A cross-section of Mars underground ice is exposed at the steep slope that appears bright blue in this enhanced-color view from the MRO. [11]
Scientists found water reserves deep in Mars' crust using InSight data, suggesting potential for life—but challenging drilling depths. A Hidden Ocean Is Lurking Deep Within Mars’ Crust Skip to ...
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep.

The most conspicuous feature of Mars is a sharp contrast, known as the Martian dichotomy, between the Southern and the Northern hemispheres.The two hemispheres' geography differ in elevation by 1 to 3 km.
Mars is much less tectonically active than Earth, and marsquakes are unlikely to have provided seismic waves of the required magnitude. [10] Most sizable craters on Mars date to the Late Heavy Bombardment , 4.1 to 3.8 billion years ago (the Noachian period), and are older than the landslide deposits in Valles Marineris.
