The two instances of active pingo springs are associated with substantial icings. Landform changes since Fritz M眉ller's observations in 1956 are generally minor. It is hypothesised that the concentration of hydraulic pingos in east Greenland may initially reflect residual higher heat flows following...
We also suggest that the two types of distinctive geomorphic features are attributed to fluid venting which occurs at different rates, with the mounds developing slowly over time, but the CSD forming in discrete events perhaps associated with large earthquakes....
Late holocene 'mineral palsas' and associated vegetation patterns: A case study from Lac Hendry, Northern Québec, Canada and significance for european pleistocene thermokarst Mineral palsas with thin peat covers are described from the continuous to discontinuous permafrost transition zone. They are up...
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, ...
Pingo morphology ranges from single features to complexes with over 10, from mature forms to degraded types. Evidence for different cycles of reactivation is seen. The two instances of active pingo springs are associated with substantial icings. Landform changes since Fritz Müller's observations...
Pingos are small hills with cores of ice, formed by injection and freezing of pressurized water. The possibility of pingos on Mars is of particular interest because of the associated implications for liquid water. We have systematically searched for candidate pingos using images from the High ...
Pingos are believed to grow more by means of ice segregation than by the freezing of a pool of water. The water source, and the associated positive pore water pressure, result from permafrost aggradation in sands and silts in the lake bottom under a closed system with expulsion of pore ...
Pingo-like forms (PLFs) in Utopia Planitia are the most viable candidates for pingos or collapsed pingos. Other PLFs hypothesized in the literature to be pingos may be better explained with other mechanisms than those associated with terrestrial-style pingos....
