An ancient river landscape preserved beneath the East Antarctic Ice Sheet (2023)
Journal Article
Jamieson, S. S. R., Ross, N., Paxman, G. J. G., Clubb, F. J., Young, D. A., Yan, S., …Siegert, M. J. (2023). An ancient river landscape preserved beneath the East Antarctic Ice Sheet. Nature Communications, 14(1), Article 6507. https://doi.org/10.1038/s41467-023-42152-2

The East Antarctic Ice Sheet (EAIS) has its origins ca. 34 million years ago. Since then, the impact of climate change and past fluctuations in the EAIS margin has been reflected in periods of extensive vs. restricted ice cover and the modification o...

Patterns of valley incision beneath the Greenland Ice Sheet revealed using automated mapping and classification (2023)
Journal Article
Paxman, G. (2023). Patterns of valley incision beneath the Greenland Ice Sheet revealed using automated mapping and classification. Geomorphology, 436(September), Article 108778. https://doi.org/10.1016/j.geomorph.2023.108778

The Greenland Ice Sheet covers an area of 1.7 million km2, equivalent to ∼79 % of the surface of Kalaallit Nunaat (Greenland) and ∼1.2 % of the Earth's land surface. The macro-scale geomorphology beneath the ice can provide a valuable record of past...

Inference of the timescale-dependent apparent viscosity structure in the upper mantle beneath Greenland (2023)
Journal Article
Paxman, G., Lau, H., Austermann, J., Holtzman, B., & Havlin, C. (2023). Inference of the timescale-dependent apparent viscosity structure in the upper mantle beneath Greenland. AGU advances, 4(2), 1-22. https://doi.org/10.1029/2022av000751

Contemporary crustal uplift and relative sea level change in Greenland is caused by the response of the solid Earth to ongoing and historical ice mass change. Glacial isostatic adjustment (GIA) models, which seek to match patterns of land surface dis...
