The Valley Network Record on Mars (Class 2)
LPSC Key Sessions onthe Mars Hydrological Cycle
• Tuesday Afternoon, Sess 251. Ground Ice and Climate Change {e.g., new Clifford et al. abs on water in the cryosphere}
• Wednesday Morning, Sess 401. Ancient Mars Crust
• Thursday Morning, Sess. 501. Mars Aqueous Processes
• Thursday Afternoon (3:15PM), Sess. 556. Martian Gullies
• Numerous posters!
What do we want to know in general?
• Intensity• Precipitation[?] rates?• Discharges?
• Persistence• Global or local activity?• Long-lived climate or short excursions?• Intermittency? One episode or many? Formation
Timescales…
• Environmental Requirements (and/or) Implications• Is an ‘ocean’ necessary to support a climate where it
rains or snows? Are large lakes good enough?
Main Topic Today:
• How long does it take to form the deltas for valley networks on Mars? How can we estimate this? Are the various methods reliable and consistent with other geological estimates?
