&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A clathrate is a chemical substance consisting of a lattice that traps or contains molecules. The word clathrate is derived from the Latin clathratus (clatratus), meaning &amp;#039;with bars, latticed&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
The clathrates of most importance on Mars are carbon dioxide (CO2) molecules trapped in water ice.  Such a clathrate is 85% water (by mass).  &lt;br /&gt;
&lt;br /&gt;
This carbon dioxide is removed &amp;#039;permanently&amp;#039; from the Martian atmosphere, but should the water melt, it will be released.&lt;br /&gt;
&lt;br /&gt;
Daniel J Milton hase theorized that sudden melting of buried CO2 clathrates caused explosions of gas and liquid water which caused sudden floods running away from Chaotic terrain. &amp;lt;ref&amp;gt;https://www.science.org/doi/10.1126/science.183.4125.654 |Carbon Dioxide Hydrate and Floods on Mars&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
However, as Mars has [[Atmospheric loss |lost its atmosphere]], forming clathrates in large quantities has become harder.  Kieffer (2000) suggests no significant amount of clathrates could exist near the surface of Mars.&amp;lt;ref&amp;gt;https://www.science.org/doi/10.1126/science.287.5459.1753b | Clathrates are not the culprit]] Stewart &amp;amp; Nimmo (2002) find it is extremely unlikely that CO2 clathrate is present in the Martian regolith in quantities that would affect surface modification processes.&amp;lt;ref&amp;gt;https://ui.adsabs.harvard.edu/abs/2002JGRE..107.5069S |Surface runoff features on Mars: Testing the carbon dioxide formation hypothesis&amp;lt;/ref&amp;gt; &lt;br /&gt;
&lt;br /&gt;
Deeper buried, CO2 clathrates are more stable.  They likely exist on Mars, but probably in such low amounts that their release would not greatly increase air pressure.&lt;br /&gt;
&lt;br /&gt;
