Insights into drumlin development from ground-penetrating radar at Múlajökull, Iceland, a surge-type glacier

open access: yesJournal of Glaciology, 2020
Drumlins form at the ice/bed interface through subglacial processes that are not directly observable. The internal stratigraphy of drumlins provides insight into how they developed and associated subglacial processes, but traditional stratigraphic ...

Drumlinlandschaft auf der Wasserscheide zwischen Pieksämäki und Haukivuori in Mittelfinnland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1971
A stereoscopic examination of 36 vertical air photographs at the scale 1 : 60 000, in conjunction with the new topographic maps with contour lines at the 1 : 10 000 covering about 2 450 km2 of Central Finland near Pieksämäki, has been carried out ...

Using bed-roughness signatures to characterise glacial landform assemblages beneath palaeo-ice sheets

open access: yesJournal of Glaciology, 2022
Palaeo-glacial landforms can give insights into bed roughness that currently cannot be captured underneath contemporary-ice streams. A few studies have measured bed roughness of palaeo-ice streams but the bed roughness of specific landform assemblages ...

Refraction seismic soundings on three crag and tail ridges in Central Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
In this study we describe the materials and thicknesses of tills in three crag and tail ridges located in Central Finland. According to the refraction seismic soundings the tills above the groundwater table are loose and sandy and their average seismic ...

Terrestrial Signature of a Recently-Tidewater Glacier and Adjacent Periglaciation, Windy Glacier (South Shetland Islands, Antarctic)

open access: yesFrontiers in Earth Science, 2021
Contemporary retreat of glaciers is well visible in the West Antarctic region. The aim of this study is to identify, map and quantify terrestrial glacial and periglacial landforms developed in front of Windy Glacier (Warszawa Icefield, King George Island,

GIS dataset: geomorphological record of terrestrial-terminating ice streams, southern sector of the Baltic Ice Stream Complex, last Scandinavian Ice Sheet, Poland [PDF]

open access: yesEarth System Science Data, 2021
Here we present a comprehensive dataset of glacial geomorphological features covering an area of 65 000 km2 in central west Poland, located along the southern sector of the last Scandinavian Ice Sheet, within the limits of the Baltic Ice Stream Complex ...

Spatial organization of drumlins [PDF]

open access: yesEarth Surface Processes and Landforms, 2017
AbstractIce‐sheets flowing over soft sediments produce undulations in the bed, typically of metres in relief, of which drumlins are the most abundant and widely investigated. Consensus regarding their mechanism of formation has yet to be achieved. In this paper we examine the spatial organization of drumlins in order to provide an improved description ...

Observations on the Quaternary geology of an area between the 2nd Salpausselkä and the ice-marginal formation of central Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1971
The present study deals with the Quaternary formations and especially with the drumlins in the area between the Salpausselkä system in eastern Finland and the marginal formation of central Finland (Jyväskylä).

GHOSTly flute music: drumlins, moats and the bed of Thwaites Glacier

open access: yesAnnals of Glaciology, 2022
Glacier-bed characteristics that are poorly known and modeled are important in projected sea-level rise from ice-sheet changes under strong warming, especially in the Thwaites Glacier drainage of West Antarctica.
