Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

open access: yesBoreas, Volume 55, Issue 3, Page 670-701, July 2026.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 824-836, May 2026.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

open access: yesBoreas, Volume 55, Issue 2, Page 517-541, April 2026.
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.

Famennian glaciation in the eastern side of Parnaíba Basin, Brazil: evidence of advance and retreat of glacier in Cabeças Formation

open access: yesBrazilian Journal of Geology
Glaciotectonic features studied in the siliciclastic deposits of Cabeças Formation, Upper Devonian, represent the first evidence of Famennian glaciation in Southeastern Parnaíba Basin, Brazil. Outcrop-based stratigraphic and facies analyses combined with

Neoglacial readvance of the East Antarctic Ice Sheet to the northern Drygalski Basin (western Ross Sea)

open access: yesGeoscience Letters
Our study investigates late Holocene ice-sheet activity in the northern Drygalski Basin (western Ross Sea) using a multi-proxy approach, including sediment properties, geochemical indicators, and diatom assemblages, combined with AMS 14C ages of a ...

The diamictons of Río Blanco basin, Cordon del Plata, Mendoza

open access: yes, 2020
Both the sediments and the geomorphic setting of the diamictons along Rio Blanco on the piedmont east of the Cordon del Plata indicate that they could not have been deposited there by a glacier tongue, as I and several earlier observers have suggesred Rather, they must have been deposits of long-runout debris flows, as argued by Polanski.

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

open access: yesBoreas
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

Morphology and sedimentology of murtooized terrain on the southern Fraser Plateau, British Columbia, Canada

open access: yesBoreas
Recent public releases of Light Detection and Ranging (LiDAR) data in south central British Columbia (BC), Canada have revealed several landforms resembling ‘murtoos’, previously identified across portions of Scandinavia.
