Boreas, EarlyView.We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Evolution of the eastern part of the Kuusamo Ice Lobe, based on geomorphological interpretation of high-resolution LiDAR data [PDF]
Bulletin of the Geological Society of Finland, 2017 In this article, we present new glacial geomorphological data from the eastern part of the Kuusamo Ice Lobe (KIL) in eastern Finland. The focus is on glacial lineations (about 9000 individual features) and interpretation of ice lobe evolution based on ...

Лëд и снег, 2021 The research aims to provide insight into reconstruction of the Late Pleistocene glaciations and ice retreat that followed the Last Glacial Maximum. The study is based on multi-channel seismic profiling and multibeam survey conducted on the shelf during ...

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

Two large drumlin fields in central Finland
Fennia: International Journal of Geography, 1973 The glacial morphology of the large Pieksämäki and Keitele drumlin fields, covering about 25 000 sq. km. in central Finland, has been studied. All the 14500 drumlins in the area have been mapped and classified into five morphogenetical types: rock ...

Boreas, Volume 55, Issue 1, Page 110-133, January 2026.Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Luminescence analysis of a postglacial landscape in northeastern Norway and northern Finland
Boreas, Volume 55, Issue 1, Page 164-181, January 2026.Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area. This study uses 186 pOSL measurements and 20 OSL ages to investigate the postglacial landscape evolution inside the Younger Dryas ...

Widespread Depositional Fluvial Systems in Noachis Terra, Mars
Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.Abstract Noachis Terra, in Mars' southern highlands, is a region where “warm/wet” climate models of the early Martian Climate predict high rates of precipitation but which is poorly dissected by Valley Networks (VNs). We searched for Fluvial Sinuous Ridges (FSRs, or “inverted channels”) here because they (a) provide alternate evidence to VNs for ...
