Retreat dynamics of the eastern sector of the British–Irish Ice Sheet during the last glaciation (2021)
Journal Article
Evans, D. J., Roberts, D. H., Bateman, M. D., Clark, C. D., Medialdea, A., Callard, L., …Bradley, S. L. (2021). Retreat dynamics of the eastern sector of the British–Irish Ice Sheet during the last glaciation. Journal of Quaternary Science, 36(5), 723-751. https://doi.org/10.1002/jqs.3275

The findings of BRITICE‐CHRONO Transect 2 through the North Sea Basin and eastern England are reported. We define ice‐sheet marginal oscillation between ~31 and 16 ka, with seven distinctive former ice‐sheet limits (L1–7) constrained by Bayesian stat...

Glaciers are important indicators of climate change, and recent observations worldwide document increasing rates of mountain glacier recession. Here we present approximately 200 years of change in mountain glacier extent in northern Troms and western...

The deglaciation of the western sector of the Irish Ice Sheet from the inner continental shelf to its terrestrial margin (2020)
Journal Article
Roberts, D., Ó Cofaigh, C., Ballantyne, C., Burke, M., Chiverrell, R., Evans, D., …Callard, S. (2020). The deglaciation of the western sector of the Irish Ice Sheet from the inner continental shelf to its terrestrial margin. Boreas: An International Journal of Quaternary Research, 49(3), 438-460. https://doi.org/10.1111/bor.12448

This paper provides a new deglacial chronology for retreat of the Irish Ice Sheet from the continental shelf of western Ireland to the adjoining coastline, a region where the timing and drivers of ice recession have never been fully constrained. Prev... Read More about The deglaciation of the western sector of the Irish Ice Sheet from the inner continental shelf to its terrestrial margin.

The glacial landsystem of Fjallsjökull, Iceland: Spatial and temporal evolution of process-form regimes at an active temperate glacier (2020)
Journal Article

The glacial landsystem of Fjallsjökull, Iceland: Spatial and temporal evolution of process-form regimes at an active temperate glacier. Geomorphology, https://doi.org/10.1016/j.geomorph.2020.107192

This study assesses the spatial and temporal evolution of the glacial landsystem signature at Fjallsjökull, southeast Iceland, using (a) mapping of the glacial geomorphology and surficial geology and (b) repeat uncrewed aerial vehicle (UAV) surveys....

Controls on jökulhlaup-transported buried ice melt-out at Skeiðarársandur, Iceland: Implications for the evolution of ice-marginal environments (2020)
Journal Article
Blauvelt, D. J., Russell, A. J., Large, A. R., Tweed, F. S., Hiemstra, J. F., Kulessa, B., …Waller, R. I. (2020). Controls on jökulhlaup-transported buried ice melt-out at Skeiðarársandur, Iceland: Implications for the evolution of ice-marginal environments. Geomorphology, 360, Article 107164. https://doi.org/10.1016/j.geomorph.2020.107164

High-magnitude jökulhlaups, glacier margin position and ice-thickness have been identified as key controls on sandur evolution. Existing models however have focused primarily on observations made during short windows of time and often do not account...

Sub‐annual moraine formation at an active temperate Icelandic glacier (2020)
Journal Article

This paper presents detailed geomorphological and sedimentological investigations of small recessional moraines at Fjallsjökull, an active temperate outlet of Öræfajökull, southeast Iceland. The moraines are characterised by striking sawtooth or hair... Read More about Sub‐annual moraine formation at an active temperate Icelandic glacier.

The Neutral Hills Uplands of southern Alberta, Canada is an area of complex and varied glacial landforms dominated by glacitectonic compressional structures but also containing expansive areas of hummocky terrain and kame and kettle topography. It li... Read More about Glacial geomorphology of the Neutral Hills Uplands, southeast Alberta, Canada: The process-form imprints of dynamic ice streams and surging ice lobes.

Equifinality and preservation potential of complex eskers (2019)
Journal Article

Eskers are useful for reconstructing meltwater drainage systems of glaciers and ice sheets. However, our process understanding of eskers suffers from a disconnect between sporadic detailed morpho‐sedimentary investigations of abundant large‐scale anc...
