Last glacial ice sheet dynamics offshore NE Greenland – a case study from Store Koldewey Trough [PDF]
The presence of a grounded Greenland Ice Sheet on the northeastern part of the Greenland continental shelf during the Last Glacial Maximum is supported by new swath bathymetry and high-resolution seismic data, supplemented with multi-proxy analyses of ...

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

Isotopic composition on ground ice in Western Yamal (Marre-Sale)
The profile of Quaternary sediments near Marre-Salle polar station, Western Yamal Peninsula, has large bodies of tabular ground ice. This profile is considered strata-typical and critical in understanding of paleogeographic conditions of the Arctic in ...

Microtopographic control on the ground thermal regime in ice wedge polygons [PDF]
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 ...

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

OXYGEN STABLE ISOTOPE VARIATION IN LATE HOLOCENE ICE WEDGES IN YAMAL PENINSULA AND SVALBARD
The stable oxygen isotope composition of Late Holocene syngenetic ice wedges from the Erkutayakha River valley in the Yamal Peninsula and from the Adventdalen valley in Svalbard was studied. It was demonstrated that the studied ice wedges located 2000 km
