Glacier variations in the European Alps at the end of the last glaciation

Cuadernos de Investigación Geográfica, 2015
The Last Glacial Maximum in the Alps lasted from approximately 30 to 19 ka. Glaciers reached out onto the forelands on both sides of the main Alpine chains, forming piedmont lobes in the north and filling the Italian amphitheatres to the south.

Build-up and chronology of blue ice moraines in Queen Maud Land, Antarctica

Quaternary Science Advances, 2020
Blue ice moraines are common supraglacial landforms in Antarctica and they are considered to record the ice volume fluctuations. In this study, we use photogrammetry and the analysis of multiple cosmogenic nuclides (10Be, 26Al, and in-situ 14C) in ...

Soil and microbial responses to wild ungulate trampling depend more on ecosystem type than trampling severity

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Multi-source deep-learning approach for automatic geomorphological mapping: the case of glacial moraines

Geo-spatial Information Science
Landform mapping is the initial step of many geomorphological analyses (e.g. assessment of natural hazards and natural resources) and requires vast resources to be applied to wide areas at high-resolution.

Zur Problematik der pleistozänen und holozänen Vergletschernung Süd-Kamtschatkas – erste Ergebnisse bodengeographischer Untersuchungen [PDF]

Eiszeitalter und Gegenwart, 1996
In the Plotnikova Valley, west of Petropavlovsk in South Kamchatka, two valley drift complexes can be identified. They are correlated with glaciofluvial terraces. The older, so called M1-moraines descend to about 300 m a.s.l.

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Structure of end moraines and dynamics of the recession phase of the Warta Stadial ice sheet, Kłodawa Upland, Central Poland

Open Geosciences, 2020
The occurrence of end moraines reflects the dynamics of an ice sheet, and their inner structure is determined by processes taking place in marginal zones.

Environmental dynamics and timing of the late Eemian interglacial to the Weichselian pleniglacial at Lichtenberg, Germany: implications for the Oerel and Glinde interstadials

Boreas, EarlyView.
The terrestrial sediment archives of northern Germany provide important insights into Late Pleistocene climate variability, but continuous and well‐dated records remain rare. In particular, the age and stratigraphic position of the Oerel and Glinde interstadials within the Early Weichselian to pleniglacial transition remain poorly constrained.
