frozen ground or permafrost

salinity

(1) a general property of aqueous solutions caused by the alkali, alkaline earth, and metal salts of strong acids (Cl, SO4 and NO3) that are not hydrolyzed (2) in soil science, the ratio of the weight of salt in a soil sample to the total weight of the sample.

saline permafrost

permafrost in which part or all of the total water content is unfrozen because of freezing-point depression due to a high dissolved-solids content of the pore water.

river talik

a layer or body of unfrozen ground occupying a depression in the permafrost table beneath a river.

retrogressive thaw slump

a slope failure resulting from thawing of ice-rich permafrost.

reticulate-blocky cryostructure

the cryostructure in which horizontal and vertical ice veins form a three-dimensional, irregular rectangular lattice.

reticulate ice

a network of horizontal and vertical ice veins forming a three-dimensional, often rectangular or square lattice.

reticulate cryostructure

the cryostructure in which horizontal and vertical ice veins form a three-dimensional, rectangular or square lattice.

residual thaw layer

a layer of thawed ground between the seasonally frozen ground and the permafrost table.

residual stress

the effective stress generated in a thawing soil if no volume change is permitted during thaw.

relict permafrost

permafrost existing in areas where permafrost can not form under present climatic conditions; reflects past climatic conditions that were colder.
