For those who do not have access, note that Elsevier/ScienceDirect typically offers free online access to each year's first published issue of any given journal, access that expires at the end of the year. In this instance, the publishers are offering free online access to the January 15, 2006 issue of Earth and Planetary Science Letters. If the previous link doesn't work, try this one.

Note there are two Mars-related papers.
