The martian polar caps are among the most dynamic regions on Mars, growing substantially in winter as a significant fraction of the atmosphere freezes out in the form of CO2 ice. Unusual dark spots, fans and blotches form as the south-polar seasonal CO2 ice cap retreats during spring and summer. Small radial channel networks are often associated with the location of spots once the ice disappears. The spots have been proposed to be simply bare, defrosted ground; the formation of the channels has… 
Conceptual Model for the Removal of Cold‐Trapped H2O Ice on the Mars Northern Seasonal Springtime Polar Cap
The transport of H2O ice along the retreating north polar seasonal CO2 ice cap has previously been modeled and observed. Spectral observations show that H2O ice forms on the interior of the seasonal
Material ejection by the cold jets and temperature evolution of the south seasonal polar cap of Mars from THEMIS/CRISM observations and implications for surface properties
As the seasonal CO2 ice polar caps of Mars retreat during spring, dark spots appear on the ice in some specific regions. These features are thought to result from basal sublimation of the transparent

No signature of clear CO2 ice from the ‘cryptic’ regions in Mars' south seasonal polar cap
TLDR
Near-infrared imaging spectroscopy of the south seasonal cap of Mars indicates that the low albedo results from extensive dust contamination close to the surface of a CO2 ice layer, which could be linked to atmospheric circulation patterns.
Basal Sublimation of the Seasonal Caps and Sub-Ice Gas Flow: A Major Geomorphological Agent in the Martian Polar Regions
Spots, Fans and Spiders Formation Model In [1] and [2] models, the seasonal cap is opaque to the solar radiation before ~Ls 190. During the spring (Ls 190 to ~Ls 240), a self cleaning process [3]
Cold jets in the Martian polar caps
[1] Mars seasonal polar caps display dark ice, local darker spots, aligned elongate patches, and radially dendritic forms that reverse albedo contrast. The unexpected variety and sequence of these
Martian Seasonal South Polar Cap as a Source of Atmospheric Water Vapour
The Martian climate is mainly controlled by CO2, as it represents 95% of the atmosphere. Understanding the behavior of surface/atmosphere interactions is a major scientific issue. Here we focus on

Perennial water ice identified in the south polar cap of Mars
TLDR
This work presents the first direct identification and mapping of both carbon dioxide and water ice in the martian high southern latitudes, at a resolution of 2 km, during the local summer, when the extent of the polar ice is at its minimum.

TLDR
The Mars Odyssey Thermal Emission Imaging System (THEMIS) has discovered water ice exposed near the edge of Mars' southern perennial polar cap, indicating that surface H2O ice may be widespread around and under the perennial CO2 cap.
