Conference coming up next week: <br /><br />7th International Conference on Mars. <br />July 9-13, 2007 <br />Pasadena, CA <br />http://www.lpi.usra.edu/meetings/7thmars2007/ <br /><br /><br />Some interesting reports at the conference: <br /><br />TRANSIENT WATER PONDING IN CENTRAL ARAM CHAOS: INDICATIONS FROM MGS <br />MOC AND THEMIS OBSERVATIONS. <br />M. I. Fomitchev1, 1Pennsylvania State University, CS&E, 111J IST, <br />University Park, PA 16802 <br />E-mail: *...@psu.edu <br />Seventh International Conference on Mars. <br />http://www.lpi.usra.edu/meetings/7thmars2007/pdf/3001.pdf <br /><br />Dr. Fomitchev's web site: <br /><br />Dr. Max I. Fomitchev. <br />http://www.cse.psu.edu/~mif10/ <br /><br /><br />GEOMETRIC AND THERMAL CONTEXT OF GULLIED SLOPES IN THE NORTHERN <br />HEMISPHERE OF MARS: PREDICTION AND MEASUREMENT. <br />Martha S. Gilmore1, Ann M. Ollila1, Nina L. Lanza1,2, and Ashwin R. <br />Vasavada3 1Department of Earth and Environmental Sciences, Wesleyan <br />University, 265 Church St. Middletown CT 06459 *...@wesleyan.edu, <br />2Dept. of Earth and Planetary Sciences, Univ. of New Mexico, <br />Albuquerque, 3Jet Propulsion Laboratory, California Institute of <br />Technology, Pasadena, CA. <br />Seventh International Conference on Mars. <br />"Conclusion: Gullies are sensitive to seasonal solar <br />insolation and temperatures. We propose that gullies <br />form on slopes with geometries (elevation, slope, azimuth) <br />that result in a specific temperature pressure <br />environment (not too hot and not too cold) conducive <br />to both the preservation and melting of ice in the uppermost <br />subsurface." <br />http://www.lpi.usra.edu/meetings/7thmars2007/pdf/3320.pdf <br /><</safety_wrapper> <div class="Discussion_UserSignature"> </div>

Dr. Fomitchev's full submitted journal article is available on his website:<br /><br />Transient Melt Water Ponding in Central Aram Chaos on Mars.<br />http://www.cse.psu.edu/~mif10/AramChaosWater.doc [12.5 mbytes]<br /><br />From the article:<br /><br />"Ground ice<br />As one can see from Table 1 Amazonis, Arabia, Aram Chaos, Elysium and Hellas basin areas allow a maximum of 3.5 hours per day for liquid water to persist on the surface with between 50 and 275 days per Martian year when the transient water conditions are met. It should be emphasized that within the highlighted areas the most likely spots for transient liquid water to occur would be craters and depressions where higher surface pressure provides more stable conditions and the subsurface ground ice is present."<br /><br />Bob Clark <br /><br /> <div class="Discussion_UserSignature"> </div>
