A layer of ground which, because of its frozen state, has a low enough permeability to act as a confining bed for an aquifer. Annual freezing can turn the Active Layer into a Cryogenic Aquiclude.
A special type of chilled mirror hygrometer capable of measuring very low frost points. These low temperatures at the mirror are attained by evaporating low boiling point or cryogenic fluids. This str
ong cooling capability allows cryogenic hygrometers to maintain reasonable response times even at low frost points. Cryogenic hygrometers are used for airborne humidity measurements from aircraft or balloons, but also in semiconductor industries for monitoring very dry environmental conditions needed in manufacturing processes.
An interval in geologic time during which geologic, geomorphic, and climatic conditions favored large-scale glacier formation; a period that tended to produce an ice age or glacial period.
In international materials science, this term refers to temperatures generally below -50˚C, but usually to temperatures within a few degrees of absolute zero (-273˚C).

1. The study of ice and snow. 2.In Europe, a synonym for glaciology. Note: The term cryology has become almost meaningless unless it is defined in context. (Arctic and Subarctic Terms, Arctic, Desert
Tropic Information Center Pub. A-105, 1955.) 3.The study of sea ice.
Cryomere refers to a cold period and is the opposite of a Thermomere, which is a warm climate period. According to the importance, duration, intensity, temperatures and precipitation characteristics d
ifferent categories have been proposed such as: Category Cryomere Thermomere 1 Glacial Interglacial 2 Stadial Interstadial 3 Phase Interval 4 Step Stage In the mountain environment, the spatial scope of the glaciations, from a glacial (Category 1) up to a step (Category 4), were considered to be of 100 km, between 50 and 100 km, between 15 and 50 km and less than 15 km, respectively.
Gently inclined erosion surfaces developed at the foot of valley sides or marginal slopes of geomorphological units developed by cryogenic processes under Periglacial conditions.
