These are fairly solid scientific articles, written within a space limit so they are terse and may be difficult to read. Files are in pdf format so you will need Adobe's pdf reader either integrated with your browser or as a stand-alone application.
 

The Introduction to each one gives an overview of the topic.
 

• 1    Item 1505 - One of the key areas of "flood" outbursts can be interpreted as a CO2 outburst

Athabasca Vallis is a 2003 MER target, interpreted as a site of recent liquid water outbursts and lava flows. Here, we examine unusual linear cone chains within the flow channels and find that CO2 may have had a major role, either alone, or with H2O.

• 2    Item 1509 - Basal melting of the polecaps is impossible, unless they are CO2-rich

Basal melting of the permanent polecaps of Mars is often inferred from terrain features. We show that a water ice cap cannot melt under likely conditions, so either the polecap contains large amounts of CO2, or the evidence for melting is incorrect.
