a long narrow area of pack ice, about 1 kilometer (0.6 mile) or less in width, usually composed of small fragments detatched from the main mass of ice, and run together under the influence of wind or current.
permafrost beneath a glacier.
a layer or body of unfrozen ground beneath a glacier in an area with permafrost.
the transition of a substance from the solid phase directly to the vapor phase, or vice versa, without passing through an intermediate liquid phase.
ice formed by reverse sublimation of water vapour on cold surfaces.
water occurring in the noncryotic ground below the permafrost.
a glacier whose temperature regime is between polar and temperate; usually predominantly below freezing, but could experience extensive summer melt.
permafrost occurring beneath the sea bottom.
a layer or body of unfrozen ground beneath the seabottom, and forming part of the subsea permafrost.
Provides the ability to narrow your search by providing specific temporal ranges and or spatial coordinates.
the permanent ice zone that remains in summer after all melting has occurred.
ablation hollows that develop during intense sunshine.
dark spot on the sun, with cooler-than-average temperatures and strong magnetic activity
the condition when a liquid remains in the liquid state even through its temperature is below its freezing point.
cooling of a liquid to a temperature below its freezing point, without causing solidification.
the condition which occurs in the atmosphere when the relative humidity is greater than 100%.
dust and/or rock that rides the surface of a glacier.
water occurring in unfrozen ground above perennially frozen ground.
a distinct soil micromorphology, resulting from the effects of freezing and thawing processes, in which coarser soil particles have vertical or near-vertical orientation.
the cumulative number of degree-days below 0 degrees Celsius for the surface temperature (of the ground, pavement, etc.) during a given time period.
