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

open access: yesBoreas, 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.

Climatic control on the peak discharge of glacier outburst floods

open access: yes, 2007
Lakes impounded by natural ice dams occur in many glacier regions. Their sudden emptying along subglacial paths can unleash similar to 1 km(3) of floodwater, but predicting the peak discharge of these subglacial outburst floods ('jokulhlaups') is ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Remote Sensing Risk Assessment of Valdez Glacier Lake [PDF]

open access: yes, 2012
Can remote sensing techniques be used to determine the probability of an outburst from the Valdez Glacier Lake, and to detect downstream areas affected by a possible glacier lake outburst ...

Digital landscapes of deglaciation:identifying Late Quaternary glacial lake outburst floods using LiDAR [PDF]

open access: yes, 2016
High resolution DEMs obtained from LiDAR topographic data have led to improved landform inventories (e.g. landslides and fault scarps) and understanding of geomorphic event frequency.

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, 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.

Mapping and monitoring of glacier lake outburst floods using geospatial modelling approach for Darkut valley, Pakistan

open access: yesMeteorological Applications, 2020
Climate change and human activities have resulted in the receding of glaciers throughout the world including Pakistan. Glacier lake outburst floods (GLOFs) are amongst the most common climate‐change‐induced hazards in northern Pakistan.

Outburst of the Spartakovskoye glacier-dammed lake and changes of the outlet glacier of the Semyonov-Tyan-Shansky Ice Cap, Severnaya Zemlya, in 2021

open access: yesЛëд и снег, 2023
In the second half of August 2021, outburst flood from the Spartakovskoe Lake, one of the largest glacierdammed lakes in the Russian sector of the Arctic, occurred on the Bolshevik Island (the Severnaya Zemlya archipelago).

Determining the Events in a Glacial Disaster Chain at Badswat Glacier in the Karakoram Range Using Remote Sensing

open access: yesRemote Sensing, 2021
The Karakoram mountain range is prone to natural disasters such as glacial surging and glacial lake outburst flood (GLOF) events. In this study, we aimed to document and reconstruct the sequence of events caused by glacial debris flows that dammed the ...

Inverse Grading Emerges From Particle‐Scale Migration Under Seasonal Freeze‐Thaw Forcing: Evidence From Multi‐Year Monitoring and Physical Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Inverse grading, where coarse particles overlay finer materials, is common on talus slopes, yet its progressive formation under realistic conditions is rarely quantified. We integrate multi‐year field observations with controlled freeze‐thaw experiments to elucidate the processes driving particle migration that result in inverse grading and ...
