Dissolved organic carbon loss from Yedoma permafrost amplified by ice wedge thaw
Environmental Research Letters, 2013 Pleistocene Yedoma permafrost contains nearly a third of all organic matter (OM) stored in circum-arctic permafrost and is characterized by the presence of massive ice wedges.

Sedimentological characteristics of ice-wedge polygon terrain in Adventdalen (Svalbard) – environmental and climatic implications for the late Holocene [PDF]
Solid Earth, 2014 Ice wedges are widespread periglacial features in the landscape of Adventdalen, Svalbard. The networks of ice wedges have created areas with well-developed polygonal terrains in the lowest fluvial terraces in this valley.

Eine begrabene Solifluktionsdecke und ihr Einfluß auf die heutige Vegetation: Beobachtungen auf einer Bliesterterrasse (Saarland) [PDF]
Eiszeitalter und Gegenwart, 1964 In the lower Blies valley the author discovered a periglacial mudflow consisting of white marl and fragments of limestone, surmounted by 25-30 cm river-sand belonging to a Riß-terrace. The surface of these deposits was covered by fossil ice-wedges.

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 ...

Computational Geometry, 2013 What is the minimum angle $ >0$ such that given any set of $ $-directional antennas (that is, antennas each of which can communicate along a wedge of angle $ $), one can always assign a direction to each antenna such that the resulting communication graph is connected?

The northern sector of the last British ice sheet : maximum extent and demise [PDF]
, 2008 Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet.

A Numerical Ice Load Prediction Model Based on Ice-Hull Collision Mechanism
Applied Sciences, 2020 A simplified numerical model is introduced to predict ice impact force acting on the ship hull in level ice condition. The model is based on ice-hull collision mechanisms and the essential ice breaking characteristics. The two critical ice failure modes,

Enhanced heterogeneous ice nucleation by special surface geometry
Nature Communications, 2017 Understanding ice nucleation is important for the development of accurate cloud models. Here Biet al. show that sharp wedges can enhance ice nucleation both when the wedge geometry matches the ice lattice and when such matching is absent, in which case ...
