Subglacial bed form morphology controlled by ice speed and sediment thickness
Geophysical Research Letters, 2016 Subglacial bed forms (drumlins, ribbed moraines, and megascale glacial lineations) are enigmatic repetitive flow‐parallel and flow‐transverse landforms common in glaciated landscapes.

Drumlinkerne, ältere Würmschotter und das Würm-Interstadial-Profil von Hörmating/Obb. [PDF]
Eiszeitalter und Gegenwart, 1960 Several new gravel pits have been opened near Rosenheim in the formerly glaciated foreland of the Alps in Bavaria. Some new observations could be made in the centre of the Inn-Piedmont Glaciation area. There has been no „Stephanskirchen Stage" during the

Drumlinization and drumlin-forming instabilities: viscous till mechanisms [PDF]
Journal of Glaciology, 1998 AbstractGlacially induced flow naturally tends to thin and extended till cover through shock formation, even in the absence of longitudinal gradients in the applied stress. Thicker till cover has an increased effective pressure at its surface and base, a lower sliding velocity or deformation rate and above a critical thickness, a decrease in wave ...

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.

High-resolution LiDAR mapping of glacial landforms and ice stream lobes in Finland [PDF]
Bulletin of the Geological Society of Finland, 2017 Newly available high resolution airborne LiDAR (Light Detection And Ranging) technology is generating unprecedented next-generation imagery of Earth surface features. LiDAR datasets are being employed by the Geological Survey of Finland (GTK) as part of

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.

Glacial geology and till geochemistry in ore exploration in the Tervola area, southern Finnish Lapland [PDF]
Bulletin of the Geological Society of Finland, 1998 Glacial geology and till geochemistry were studied in an ore exploration project in the Palaeoproterozoic Peräpohja Schist Belt in the Tervola area of southern Finnish Lapland. The starting point for the exploration were numerous Au-Cu-rich erratics, the

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.
