Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, EarlyView.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas, EarlyView.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

Rock avalanches on glaciers

, 2011
This thesis examines relations between rock avalanches and the glaciers on which they are deposited. I have attempted to understand a geophysical phenomenon from two viewpoints: sedimentology and glaciology. The contributions are both methodological, and practical. I have used a GIS to quantify debris sheet geomorphology. A thorough characterization of

Geographic distributions of rock glacier in Turkey: The case study of Erciyes rock glacier

, 2021
Kaya buzulu, periglasiyel ve permafrost oluşum süreçlerinin en önemli göstergelerinden biridir. Genellikle kıtasal iklim bölgelerinde bulunur. Özellikle soğuk ve kurak iklimin hâkim olduğu dağların yüksek kesimlerinde görülür. Kaya buzulları, donmuş kaya ve buzun karışımıyla talus üzerinde oluşur. Maalesef şimdiye kadar Türkiye'de bu konu hakkında

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

Boreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.
