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.

The effect of human activities on moisture content of soils and underlying permafrost from the McMurdo Sound region, Antarctica [PDF]
, 1994 Soils and the underlying permafrost from undisturbed sites and sites that had been disturbed by construction activities at Marble Point and Pram Point in the McMurdo Sound region were sampled from excavated pits and drill cores. Gravimetric moisture (ice)

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 chronostratigraphy of Late Pleistocene glacial and periglacial aeolian activity in the Tuktoyaktuk Coastlands, NWT, Canada [PDF]
, 2006 Aeolian periglacial sand deposits are common in the Tuktoyaktuk Coastlands of Western Arctic Canada. Regionally extensive and thick aeolian sand-sheet deposits have been observed in two major stratigraphic settings: within a sand unit characterized by ...

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,
