beaded stream

a stream characterized by narrow reaches linking pools or small lakes.

basal-layered cryostructure

the cryostructure of a frozen layered deposit of gravel and boulders that is saturated with ice.

basal cryostructure

the cryostructure of a frozen deposit of boulders that is saturated with ice.

basal cryopeg

a layer of unfrozen ground that is perennially cryotic (t < 0 degrees Celsius), forming the basal portion of the permafrost.

barrens

areas of discontinuous vegetation cover in the polar semi-desert of the high arctic.

banded cryogenic fabric

a distinct soil micromorphology, resulting from the effects of freezing and thawing processes, in which soil particles form subhorizontal layers.

artificial ground freeezing

the process of inducing or maintaining a frozen condition in earth materials by artificial means.

approximate thawing index

the cumulative number of degree-days above 0 degrees Celsius for a given time period, calculated from the mean monthly temperatures for a specific station without making corrections for negative degree-days in spring and fall.

approximate freezing index

the cumulative number of degree-days below 0 degrees Celsius for a given time period, calculated from the mean monthly temperatures for a specific station without making corrections for positive degree-days in spring and fall.

anti-syngenetic ice wedge

an ice wedge that grows progressively downwards into a receding slope, in a direction normal (perpendicular) to the surface.
