A note on hysteresis in glaciology
Applied Mathematics Letters, 2000 Recent studies on the mechanism governing the Laurentide ice sheet oscillations of the Last Ice Age focus on the most critical effect of the basal hydraulic processes enhanced when the ice is sliding along soft deformable beds. To understand the import of this, we consider {A. C. Fowler} and \textit{C. Johnson}'s 0-D hydrological flow model [J. Glaciol.

A talus rock glacier in Nantlle Valley, North Wales
Journal of Quaternary Science, EarlyView.ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Control of Ocean Temperature on Jakobshavn Isbræ's Present and Future Mass Loss
Geophysical Research Letters, 2018 Large uncertainties in model parameterizations and input data sets make projections of future sea level rise contributions of outlet glaciers challenging.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France
Journal of Quaternary Science, EarlyView.ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Journal of Quaternary Science, EarlyView.ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool
Journal of Quaternary Science, EarlyView.ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Journal of Quaternary Science, EarlyView.ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Remote Sensing, 2022 Although measurements of thickness and internal structure of glaciers are substantial for the understanding of their evolution and response to climate change, detailed data about polythermal glaciers, are scarce.
