Valles Marineris flood may have raised ancient Martian sea level by 34 metres

The flood, from the ancient canyon system, the largest in the Solar System, is estimated to have released 1,245 trillion cubic metres of water and may have raised the global mean level of the hypothesised ancient Martian ocean by about 34 metres, according to a new study published online in the peer-reviewed journal Icarus.
