| In undersaturated conditions, the ice content is too low to distinguish between permafrost and permafrost-free areas using geophysical methods, and in particular, with geoelectric radar methods. |
| If the air is undersaturated, with a relative humidity of less than 100 percent, it gains water vapour because the rate of evaporation exceeds the rate of condensation. |
| Furthermore, in slopes, the permafrost is often dry or undersaturated with ice. |
| They further show that the undersaturated regions were also those experiencing a freshening of surface waters due to melting sea ice. |
| Silica saturation is a classification of minerals and rocks as oversaturated, saturated, or undersaturated with respect to silica. |
| At 550 ppm CO2, half of the ocean south of 60°S becomes undersaturated. |
