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...

The landscape of the Karrat region, central West Greenland, contrasts between high elevation low relief topography, steep sided fjords and deep bathymetric troughs. The mechanisms controlling its formation are highly debated, with initial work sugges...

Journal Article
Bradwell, T., Small, D., Fabel, D., Smedley, R. K., Clark, C. C., Saher, M. H., …Ó Cofaigh, C. (2019). Ice-stream demise dynamically conditioned by trough shape and bed strength. Science Advances, 5(4), Article eaau1380. https://doi.org/10.1126/sciadv.aau1380

Ice sheet mass loss is currently dominated by fast-flowing glaciers (ice streams) terminating in the ocean as ice shelves and resting on beds below sea level. The factors controlling ice-stream flow and retreat over longer time scales (>100 years), e... Read More about Ice-stream demise dynamically conditioned by trough shape and bed strength.

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.
