Active Layer Warming and Thickening on CALM‐S JGM, James Ross Island, in the Period 2013/14–2022/23
Permafrost and Periglacial Processes, EarlyView.ABSTRACT The Circumpolar Active Layer Monitoring‐South (CALM‐S) site was established near the Johann Gregor Mendel (JGM) research station on James Ross Island in February 2014. The CALM‐S JGM grid, measuring 80 × 70 m, encompasses two distinct lithological units: a Holocene marine terrace (covering approximately 75% of the grid) and Cretaceous ...

PhotonicsOptical fiber is increasingly used for both communication and distributed sensing of temperature and strain in environmental studies. In this work, we demonstrate the viability of unreinforced fiber tethers (bare fiber) for Raman-based distributed ...

Neoglacial and historical glacier changes around Kangersuneq fjord in southern West Greenland [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2012 The Nuup Kangerlua region in southern West Greenland became eglaciated in the early Holocene and by the mid-Holocene, the margin of the Inland Ice was located east of its present position.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The paper investigates environmental conditions prevailing at the southern margin of the European periglacial domain in NW Hungary (Kemeneshát area) during the Late Pleistocene. Samples of sediments infilling sand wedges and their host sediments were analyzed by examining the grain‐size distributions, as well as the morphology and ...

Can shrubs help to reconstruct historical glacier retreats?
Environmental Research Letters, 2012 In the 21st century, most of the world’s glaciers are expected to retreat due to further global warming. The range of this predicted retreat varies widely as a result of uncertainties in climate and glacier models.

Boreas, EarlyView.Environmental changes on the northern part of Taymyr Peninsula during the last 62 ka were reconstructed based on pollen assemblages throughout a 46‐m‐long sediment core from Lake Levinson‐Lessing (74°27′54″N, 98°39′58″E). Environmental changes on the northern Taymyr Peninsula were reconstructed based on a new pollen record from a 46‐m‐long sediment ...

Surface oscillations in channeled snow flows
, 2007 An experimental device has been built to measure velocity profiles and friction laws in channeled snow flows. The measurements show that the velocity depends linearly on the vertical position in the flow and that the friction coefficient is a first-order

Geometrical force balance in glaciology [PDF]
Journal of Geophysical Research: Solid Earth, 2003 The analytical force balance traditionally used in glaciology relates gravitational forcing to ice surface slope for sheet flow and to ice basal buoyancy for shelf flow. It is unable to represent stream flow as a transition from sheet flow to shelf flow by having gravitational forcing gradually passing from being driven by surface slope to being driven
