Slowdown of Shirase Glacier, East Antarctica, caused by strengthening alongshore winds (2022)
Journal Article
Miles, B. W., Stokes, C. R., Jenkins, A., Jordan, J. R., Jamieson, S. S., & Gudmundsson, G. H. (2022). Slowdown of Shirase Glacier, East Antarctica, caused by strengthening alongshore winds. The Cryosphere, 17, 445-456. https://doi.org/10.5194/tc-17-445-2023Around large parts of West Antarctica and in Wilkes Land, East Antarctica, increased wind-forced intrusions of modified Circumpolar Deep Water (mCDW) onto the continental shelf have been associated with mass loss over the last few decades. Despite co... Read More about Slowdown of Shirase Glacier, East Antarctica, caused by strengthening alongshore winds.
Response of the East Antarctic Sheet to Past and Future Climate Change (2022)
Journal Article
Stokes, C. R., Abram, N. J., Bentley, M. J., Edwards, T. L., England, M. H., Foppert, A., …Whitehouse, P. (2022). Response of the East Antarctic Sheet to Past and Future Climate Change. Nature, 608, 275-286. https://doi.org/10.1038/s41586-022-04946-0The East Antarctic Ice Sheet contains the vast majority of Earth’s glacier ice (about 52 metres sea-level equivalent), but is often viewed as less vulnerable to global warming than the West Antarctic or Greenland ice sheets. However, some regions of... Read More about Response of the East Antarctic Sheet to Past and Future Climate Change.
The Last Glacial Maximum and Deglacial History of the Seno Skyring Ice Lobe (52°S), Southern Patagonia (2022)
Journal Article

Frontiers in Earth Science, 10, https://doi.org/10.3389/feart.2022.892316There are still many uncertainties about the climatic forcing that drove the glacier fluctuations of the Patagonian Ice Sheet (PIS, 38–55°S) during the last glacial period. A key source of uncertainty is the asynchrony of ice lobe fluctuations betwee...

High spatial and temporal variability in Antarctic ice discharge linked to ice shelf buttressing and bed geometry (2022)
Journal Article
Miles, B., Stokes, C., Jamieson, S., Jordan, J., Gudmundsson, G., & Jenkins, A. (2022). High spatial and temporal variability in Antarctic ice discharge linked to ice shelf buttressing and bed geometry. Scientific Reports, 12, Article 10968. https://doi.org/10.1038/s41598-022-13517-2Antarctica’s contribution to global mean sea level rise has been driven by an increase in ice discharge into the oceans. The rate of change and the mechanisms that drive variability in ice discharge are therefore important to consider in the context...

Palaeoglaciation in the low latitude, low elevation tropical Andes, northern Peru (2022)
Journal Article
Lee, E., Ross, N., Henderson, A., Russell, A., Jamieson, S., & Fabel, D. (2022). Palaeoglaciation in the low latitude, low elevation tropical Andes, northern Peru. Frontiers in Earth Science, 10, Article 838826. https://doi.org/10.3389/feart.2022.838826Characterising glaciological change within the tropical Andes is important because tropical glaciers are sensitive to climate change. Our understanding of glacier dynamics and how tropical glaciers respond to global climate perturbations is poorly co...

Large interannual variability in supraglacial lakes around East Antarctica (2022)
Journal Article

Nature Communications, 13(1), https://doi.org/10.1038/s41467-022-29385-3Antarctic supraglacial lakes (SGLs) have been linked to ice shelf collapse and the subsequent acceleration of inland ice flow, but observations of SGLs remain relatively scarce and their interannual variability is largely unknown. This makes it diffi... Read More about Large interannual variability in supraglacial lakes around East Antarctica.
