Luminescence dating of palaeoshoreline deposits from Khyargas Nuur, Western Mongolia: A comparative study of multigrain and single‐grain K‐feldspar dating

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The evolution of lakes in western Mongolia and their responses to climate changes and glacial meltwater input remain poorly understood. This study evaluates the reliability of multigrain and single‐grain K‐feldspar post‐infrared infrared stimulated luminescence (IRSL) (pIRIR) dating applied to palaeoshoreline sediments at Khyargas Nuur ...

Glaciological research in Antarctica

open access: yesRapport Grønlands Geologiske Undersøgelse, 1994
During 1991 and 1992 the Geological Survey of Greenland (GGU) was observer on behalf of the Danish Polar Center in and preparation of a common Nordic research effort in Antarctica. The Nordic Antarctic Research Programme (NARP) involves Norway, Sweden and Finland, which are all Antarctic Treaty Consultative Partners, whereas Denmark is an observer.

Paving the Way for Improved Representation of Coupled Physical and Biogeochemical Processes in Arctic River Plumes—A Case Study of the Mackenzie Shelf

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The

Active Layer Warming and Thickening on CALM‐S JGM, James Ross Island, in the Period 2013/14–2022/23

open access: yesPermafrost 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 ...

Environmental Conditions in the Late Pleistocene at the Southern Margin of the European Periglacial Domain (Hungary) Inferred From Quartz Grain Microtextures

open access: yesPermafrost 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 ...

Ambient Seismic Noise and Microseismicity Monitoring of Periglacial Bodies: A Case Study on the Gran Sometta Rock Glacier (NW Italian Alps)

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Ambient seismic noise and microseismicity analyses are increasingly applied for the monitoring of landslides and natural hazards. These methodologies can offer a valuable monitoring tool also for glacial and periglacial bodies, to understand the internal processes driven by external modifications in air temperature and rainfall/snowfall ...

Influence of snowpack internal structure on snow metamorphism and melting intensity on Hansbreen, Svalbard

open access: yesPolish Polar Research, 2016
This paper presents a detailed study of melting processes conducted on Hansbreen – a tidewater glacier terminating in the Hornsund fjord, Spitsbergen. The fieldwork was carried out from April to July 2010.
