A critical assessment of subglacial mega-floods: A case study of glacial sediments and landforms in south-central Alberta, Canada (2006)
Journal Article
Evans, D., Rea, B., Hiemstra, J., & Ó Cofaigh, C. (2006). A critical assessment of subglacial mega-floods: A case study of glacial sediments and landforms in south-central Alberta, Canada. Quaternary Science Reviews, 25(13-14), 1638-1667. https://doi.org/10.1016/j.quascirev.2005.12.007

The existing subglacial megaflood explanation of glacial sediment deposition and landform production in south-central Alberta relies upon four sets of observations and associated interpretations: (1) a subglacial genesis for all glacilacustrine sedim...

Flow of the West Antarctic Ice Sheet on the continental margin of the Bellingshausen Sea at the Last Glacial Maximum (2005)
Journal Article
Ó Cofaigh, C., Larter, R., Dowdeswell, J., Hillenbrand, C., Pudsey, C., Evans, J., & Morris, P. (2005). Flow of the West Antarctic Ice Sheet on the continental margin of the Bellingshausen Sea at the Last Glacial Maximum. Journal of Geophysical Research, 110, https://doi.org/10.1029/2005jb003619

Geophysical data show that during the last glaciation the West Antarctic Ice Sheet (WAIS) drained to the continental shelf edge of the Bellingshausen Sea through a cross-shelf bathymetric trough (Belgica Trough) as a grounded, fast flowing, ice strea...

Flow dynamics and till genesis associated with a marine-based Antarctic palaeo-ice stream (2005)
Journal Article
Ó Cofaigh, C., Dowdeswell, J., Allen, C., Hiemstra, J., Pudsey, C., Evans, J., & Evans, D. (2005). Flow dynamics and till genesis associated with a marine-based Antarctic palaeo-ice stream. Quaternary Science Reviews, 24(5-6), 709-740. https://doi.org/10.1016/j.quascirev.2004.10.006

Geophysical and geological data indicate that during the last glacial cycle a palaeo-ice stream drained the Antarctic Peninsula Ice Sheet (APIS) through Marguerite Bay to the edge of the continental shelf via a bathymetric trough (Marguerite Trough)....

Timing and significance of glacially influenced mass-wasting in the submarine channels of the Greenland Basin (2004)
Journal Article
Ó Cofaigh, C., Dowdeswell, J., Evans, J., Kenyon, N., Taylor, J., Mienert, J., & Wilken, M. (2004). Timing and significance of glacially influenced mass-wasting in the submarine channels of the Greenland Basin. Marine Geology, 207(1-4), 39-54. https://doi.org/10.1016/j.margeo.2004.02.009

The most extensive systems of submarine channels on the continental margins of the Norwegian–Greenland Sea occur in the Greenland Basin (72–75°N). Geophysical records show that these channels are up to 100-m deep, 4-km wide, and extend for about 300...

Depositional evidence for marginal oscillations of the Irish Sea ice stream in southeast Ireland during the last glaciation (2003)
Journal Article
Evans, D., & Ó Cofaigh, C. (2003). Depositional evidence for marginal oscillations of the Irish Sea ice stream in southeast Ireland during the last glaciation. Boreas: An International Journal of Quaternary Research, 32(1), 76-101. https://doi.org/10.1080/03009480310001047

Late Devensian/Midlandian glacial deposits on the southeast Irish coast contain a record of sedimentation at the margins of the Irish Sea ice stream (ISIS). Exposures through the Screen Hills reveal a stratigraphy that documents the initial onshore f...
