There was a related question discussed here about whether the "spiders" seen on Mars were due to subsurface CO2 or water. Kieffer et.al. proposed a CO2 gas under pressure model:

We discussed on this group whether the Gamma Ray Spectrometer would support a liquid water flow mode.
The large amounts of water found subsurface at mid to high latitudes is consistent with the water hypothesis.
The question is whether the GRS can determine if there is CO2 subsurface.
Can it distinguish between the CO2 in the atmosphere and CO2 subsurface?
Could it distinguish between CO2 subsurface and carbonate subsurface?
