The thin layer of ice might spectroscopically mask the CO2. (Like as a paint covering).
I wonder if something that penetrates deeper might notice a change, like a RADAR experiment that could measure dielectric constant. (At 0 C, dielectric constant of H2O = 88, CO2 = 1.6. [reference list here]) -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

The thin layer of ice might spectroscopically mask the CO2. (Like as a paint covering). I bet it does. If there's a lot of CO2 squestered in the caps, what are the implications for past climate conditions? I wonder if there's enough there to increase the average surface pressure significantly if released. I suspect not...but... Tom |
