Dynamics and related hazards of the Belvedere Glacier in the Italian Alps: a review

Acta Universitatis Carolinae Geographica
The Belvedere glacier is an intensively studied glacier in the Italian Alps on the east face of the Monte Rosa, which is currently undergoing a fast deglaciation connected to various slope failures and Glacial Lake Outburst Floods.

Spring-water temperature suggests widespread occurrence of Alpine permafrost in pseudo-relict rock glaciers [PDF]

The Cryosphere
Runoff originating from ground ice contained in rock glaciers represents a significant water supply for lowlands. Pseudo-relict rock glaciers contain patchy permafrost but appear to be relict, and therefore they can be misinterpreted when using standard ...

The distribution of basal motion beneath a High Arctic polythermal glacier [PDF]

, 2003
The longitudinal pattern of surface velocity of a large, predominantly colds polythermal glacier (John Evans Glacier, Ellesmere Island, Canada) was measured over summer and winter periods.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Coherent scatterers detection: application over glacier terrain using TerraSAR-X time series data [PDF]

, 2011
This paper investigates the detection of Coherent Scatterers (CSs) in ice and glacier terrain by means of TerraSAR-X time series data in the test site of the Helheim Glacier in Greenland.

Biometric Analysis of Giant and Large Murid Remains From Matja Kuru 2, Timor‐Leste

Archaeometry, EarlyView.
ABSTRACT Published research on Matja Kuru 2 (MK2) demonstrates its significance for understanding human lifestyle during the terminal Pleistocene and Holocene. Murids represent the most commonly identified taxa in the site, with specimens preliminarily classified as small, large and giant based on size comparisons.

Ice sheet attenuation from radar sounding in the frequency domain

Journal of Glaciology
Attenuation rates inferred from radar sounding offer one of the few ways to observationally constrain the large-scale temperature structure of ice sheets.

Ice thickness measurements of Guliya ice cap, western Kunlun Mountains (Tibetan Plateau), China

Journal of Glaciology, 2018
Despite their high value and importance for various glaciological applications, detailed ice thickness measurements of alpine glaciers are still very limited. Knowledge of bedrock topography is essential for paleoglaciological studies. The Guliya ice cap

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Gravity modelling of ice thickness and valley geometry on Taku Glacier (T'aak̲ú K̲wáan Sít'i), Alaska

Journal of Glaciology
Taku Glacier recently began retreating for the first time since the late 19th century but limited observations of its bed leaves uncertainties on how this retreat will proceed. In this study, we use ground-based gravity measurements to improve the extent
