Each set included about 100 craters, with the first set in the Arabia Terra region of the northern hemisphere and the second set in an area east of Hellas basin (pictured) in the southern hemisphere.
Scientists at the Tucson-based Planetary Science Institute (PSI) have found further evidence for the large role that water has likely played in shaping the Martian landscape.
Their results, which will be published in
Icarus, provide strong evidence that multiple wet and/or icy climate cycles have shaped the topography of the planet's large craters.
Icarus is the journal of the American Astronomical Society's Division of Planetary Sciences.
"Studying crater degradation in potentially ice-rich environments is vital to understanding the geology of craters and their surroundings, as well as for determining whether the ice comes from the atmosphere or from below the ground," said Daniel Berman, a PSI associate research scientist and lead author of the paper.

Comment: The concept of interdependency goes way beyond how long power is down in Canada because the sun sneezed the day before. While it's encouraging to see the connection being made between solar storms and interruption to electricity networks, sadly the wider issue of cosmic interference in Earth's systems is ignored despite the alarming reports of fireballs and meteorites piercing the planet's lower atmosphere.
The effects from a cometary impact would cause substantially greater damage to our fragile systems, producing catastrophic "cascade failures" on an ecological and humanitarian scale. It's now fairly well established that this has happened several times within humanity's lifespan: The increasing awareness that Earth meets cosmic storms on a regular basis is injecting some urgency into the issue:
UN is told that Earth needs an asteroid shield
US urged to prepare for asteroid strike
Asteroid and comet threat is a challenge to mankind
...but the signal is being drowned out by the noise generated by the twin hoaxes of the Global Pathocracy; Global Warming and the War on Terror.
Scientists note that incoming objects can produce very loud sounds, like the earth-shattering thunder that accompanied the Tunguska cometary explosion. Could the tremendous booms people are hearing be overhead explosions as space debris meets the atmosphere?
A recent chronology, by no means conclusive, of mysterious 'sonic' booms:
Feb 7th, Gold Coast, Australia
Feb 5th, Marco Island, Florida, USA
Jan 21st, Grand Island, Nebraska, USA
Jan 15th, North Carolina, USA
10th Jan, Louisiana, USA
5th Jan, Calgary, Canada
2nd Jan, Alaska, USA
30th Dec, South Carolina, USA
24th Dec, Iowa, USA
12th Nov, Indiana, USA
11th Nov, Arkansas, USA
5th Nov, New Zealand
Note how many are occurring / reported in the USA. Perhaps the Universe is trying to tell us something?
