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.

Comparison of different methods for estimating snowcover in forested, mountainous basins using LANDSAT (ERTS) images [PDF]

Snow-covered areas on LANDSAT (ERTS) images of the Santiam River basin, Oregon, and other basins in Washington were measured using several operators and methods.

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.

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.
