Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.
