Atomistic and coarse-grained simulations reveal increased ice nucleation activity on silver iodide surfaces in slit and wedge geometries [PDF]

open access: yesAtmospheric 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]

open access: yesThe 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 ...

Ground-ice stable isotopes and cryostratigraphy reflect late Quaternary palaeoclimate in the Northeast Siberian Arctic (Oyogos Yar coast, Dmitry Laptev Strait) [PDF]

open access: yesClimate 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).

Isotopic composition of oxygen and hydrogen of ice wedges in Central Yamal

open access: yesЛëд 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]

open access: yesEarth 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.

Pathways of ice-wedge degradation in polygonal tundra under different hydrological conditions [PDF]

open access: yesThe 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.

Wirkungen des pleistözänen kaltzeitlichen Klimas, insbesondere des Bodenfrostes, in den Sedimenten des östlichen Ostfalen (Eiskeile, Löß-Flugsand, asymmetrische Täler) [PDF]

open access: yesEiszeitalter 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

open access: yesQuaternary 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 ...

Stable isotope and gas properties of two climatically contrasting (Pleistocene and Holocene) ice wedges from Cape Mamontov Klyk, Laptev Sea, northern Siberia [PDF]

open access: yesThe Cryosphere, 2013
This paper presents and discusses the texture, fabric, water stable isotopes (&delta;<sup>18</sup>O, δD) and gas properties (total gas content, O<sub>2</sub>, N<sub>2</sub>, Ar, CO<sub>2</sub>, and CH ...
