Remote Sensing, 2018 Ice-wedge networks underlie polygonal terrain and comprise the most widespread form of massive ground ice in continuous permafrost. Here, we show that climate-driven thaw of hilltop ice-wedge networks is rapidly transforming uplands across Banks Island ...

Remote Sensing, 2018 The microtopography associated with ice-wedge polygons governs many aspects of Arctic ecosystem, permafrost, and hydrologic dynamics from local to regional scales owing to the linkages between microtopography and the flow and storage of water, vegetation

Atomistic and coarse-grained simulations reveal increased ice nucleation activity on silver iodide surfaces in slit and wedge geometries [PDF]
Atmospheric Chemistry and Physics, 2022 Ice clouds can form at low and moderate supercooling through heterogeneous ice nucleation on atmospheric particles. Typically, the nucleation requires active sites with special chemical and physical properties, including surface topology and roughness ...

Microtopographic control on the ground thermal regime in ice wedge polygons [PDF]
The Cryosphere, 2018 The goal of this research is to constrain the influence of ice wedge polygon microtopography on near-surface ground temperatures. Ice wedge polygon microtopography is prone to rapid deformation in a changing climate, and cracking in the ice wedge ...

Pathways of ice-wedge degradation in polygonal tundra under different hydrological conditions [PDF]
The Cryosphere, 2019 Ice-wedge polygons are common features of lowland tundra in the continuous permafrost zone and prone to rapid degradation through melting of ground ice.

Isotopic composition of oxygen and hydrogen of ice wedges in Central Yamal
Лëд и снег, 2021 New data on the distribution of the isotopes δ18О and δD of ice wedges in Central Yamal are presented. In the summer of 2019, the massive wedge ice was studied in the thermal circus of the third marine terrace.

Ice-buttressing-controlled rock slope failure on a cirque headwall, Lake District, UK [PDF]
Earth Surface Dynamics, 2023 Rock slope failures in the Lake District, UK, have been associated with deglacial processes after the Last Glacial Maximum, but the controls and timing of the failures remain poorly known.

Ground-ice stable isotopes and cryostratigraphy reflect late Quaternary palaeoclimate in the Northeast Siberian Arctic (Oyogos Yar coast, Dmitry Laptev Strait) [PDF]
Climate of the Past, 2017 To reconstruct palaeoclimate and palaeoenvironmental conditions in the northeast Siberian Arctic, we studied late Quaternary permafrost at the Oyogos Yar coast (Dmitry Laptev Strait).

Wirkungen des pleistözänen kaltzeitlichen Klimas, insbesondere des Bodenfrostes, in den Sedimenten des östlichen Ostfalen (Eiskeile, Löß-Flugsand, asymmetrische Täler) [PDF]
Eiszeitalter und Gegenwart, 1997 In the second part of the article with the title "Wirkungen des ..." a various documentation of pictures is presented to analyse the ice-wedge casts of the eastern part of Lower Saxony (Ostfalen).

Ground-ice origin and age on Herschel Island (Qikiqtaruk), Yukon, Canada
Quaternary Science Advances, 2023 Glacial legacies preserved in permafrost such as buried glacial ice of the last ice age are of increasing concern in the Western Canadian Arctic. Permafrost collapse due to melting ground ice largely follows the margins of the maximum Laurentide Ice ...
