Journal Article
Evans, D. J., Atkinson, N., & Phillips, E. (2020). Glacial geomorphology of the Neutral Hills Uplands, southeast Alberta, Canada: The process-form imprints of dynamic ice streams and surging ice lobes. Geomorphology, 350, Article 106910. https://doi.org/10.1016/j.geomorph.2019.106910

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
Storrar, R. D., Ewertowski, M., Tomczyk, A. M., Barr, I. D., Livingstone, S. J., Ruffell, A., …Evans, D. J. (2020). Equifinality and preservation potential of complex eskers. Boreas: An International Journal of Quaternary Research, 49(1), 211-231. https://doi.org/10.1111/bor.12414

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...

Dynamic ice stream retreat in the central sector of the last British-Irish Ice Sheet (2019)
Journal Article
Davies, B., Livingstone, S., Roberts, D., Evans, D., Gheorghiu, D., & Ó Cofaigh, C. (2019). Dynamic ice stream retreat in the central sector of the last British-Irish Ice Sheet. Quaternary Science Reviews, 225, Article 105989. https://doi.org/10.1016/j.quascirev.2019.105989

During the Last Glacial Maximum (LGM), ice streams of the last British-Irish Ice Sheet (BIIS) controlled ice discharge from various dispersal centres. Deglaciation was characterised by shifts in ice-divide location and changes in internal ice-sheet d...

Synsedimentary glacitectonic deformation within a glacilacustrine-esker sequence, Teesdale, Northern England (2019)
Journal Article
Phillips, E., & Evans, D. (2019). Synsedimentary glacitectonic deformation within a glacilacustrine-esker sequence, Teesdale, Northern England. Proceedings of the Geologists' Association, 130(5), 624-649. https://doi.org/10.1016/j.pgeola.2019.08.001

In glacial sedimentology there has been a recent improvement in the understanding of both progressive and polyphase deformation of glacigenic sequences, and the role played by water during these complex deformation histories. However, the processes o... Read More about Synsedimentary glacitectonic deformation within a glacilacustrine-esker sequence, Teesdale, Northern England.

The Tekapo Glacier, New Zealand, during the Last Glacial Maximum: An active temperate glacier influenced by intermittent surge activity (2019)
Journal Article
Sutherland, J. L., Carrivick, J. L., Evans, D. J., Shulmeister, J., & Quincey, D. J. (2019). The Tekapo Glacier, New Zealand, during the Last Glacial Maximum: An active temperate glacier influenced by intermittent surge activity. Geomorphology, 343, 183-210. https://doi.org/10.1016/j.geomorph.2019.07.008

Quaternary glaciations have created impressive landform assemblages that can be used to understand palaeo-glacier extent, character and behaviour, and hence past global and local glacier forcings. However, in the southern hemisphere and especially in...

Testing lichenometric techniques in the production of a new growth-rate (curve) for the Breidamerkurjokull foreland, Iceland, and the analysis of potential climatic drivers of glacier recession. Geografiska Annaler: Series A, Physical Geography, 101(3), 225-248. https://doi.org/10.1080/04353676.2019.1622919

Independent dating of closely-spaced moraines on the west Breiðamerkurjökull foreland is used to test the accuracy of the size frequency (SF) and largest lichen (5LL) lichenometric dating techniques. The 5LL technique derived the most accurate ages f...

The mixed‐bed glacial landform imprint of the North Sea Lobe in the western North Sea (2019)
Journal Article

During the last glacial cycle an intriguing feature of the British‐Irish Ice Sheet was the North Sea Lobe (NSL); fed from the Firth of Forth and which flowed south and parallel to the English east coast. The controls on the formation and behaviour of... Read More about The mixed‐bed glacial landform imprint of the North Sea Lobe in the western North Sea.
