Open Access padlockePrints

The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Pingos are ice-cored mounds or hills developed in permafrost. Two forms are identified, closed system (or hydrostatic) pingos and open system (or hydraulic) pingos. The former occur in lowland settings within the continuous permafrost zone, and the latter are more common in valley bottom and footslope localities in both discontinuous and continuous permafrost. Related smaller ground ice phenomena associated with permafrost regions are lithalsas, mineral palsas, and seasonal ground ice mounds. Relict pingos and other ground ice mounds formed during Quaternary cold stages may be indicated by circular or ovate depressions, often surrounded by raised rampart-like rims.
