Major ice‐sheet change in the Weddell Sector of West Antarctica over the last 5000 years (2019)
Journal Article
Siegert, M. J., Kingslake, J., Ross, N., Whitehouse, P. L., Woodward, J., Jamieson, S. S., …Sugden, D. E. (2019). Major ice‐sheet change in the Weddell Sector of West Antarctica over the last 5000 years. Reviews of Geophysics, 57(4), 1197-1223. https://doi.org/10.1029/2019rg000651

Until recently, little was known about the Weddell Sea sector of the West Antarctic Ice Sheet. In the last 10 years, a variety of expeditions and numerical modelling experiments have improved knowledge of its glaciology, glacial geology, and tectonic...

The Falkland Islands palaeoecological response to millennial scale climate perturbations during the Pleistocene-Holocene transition: implications for future vegetation stability in Southern Ocean islands (2019)
Journal Article
Scaife, R., Long, A., Monteath, A., Hughes, P., Bentley, M., & Stone, P. (2019). The Falkland Islands palaeoecological response to millennial scale climate perturbations during the Pleistocene-Holocene transition: implications for future vegetation stability in Southern Ocean islands. Journal of Quaternary Science, 34(8), 609-620. https://doi.org/10.1002/jqs.3150

Oceanic island flora is vulnerable to future climate warming, which is likely to promote changes in vegetation composition, and invasion of non‐native species. Sub‐Antarctic islands are predicted to experience rapid warming during the next century; t...

Reconstructions of Antarctic topography since the Eocene–Oligocene boundary (2019)
Journal Article
Paxman, G., Jamieson, S., Hochmuth, K., Gohl, K., Bentley, M., Leitchenkov, G., & Ferraccioli, F. (2019). Reconstructions of Antarctic topography since the Eocene–Oligocene boundary. Palaeogeography, Palaeoclimatology, Palaeoecology, 535, Article 109346. https://doi.org/10.1016/j.palaeo.2019.109346

Accurate models of past Antarctic ice sheet behaviour require realistic reconstructions of the evolution of bedrock topography. However, other than a preliminary attempt to reconstruct Antarctic topography at the Eocene–Oligocene boundary, the long-t...

Subglacial geology and geomorphology of the Pensacola-Pole Basin, East Antarctica (2019)
Journal Article

The East Antarctic Ice Sheet (EAIS) is underlain by a series of low‐lying subglacial sedimentary basins. The extent, geology and basal topography of these sedimentary basins are important boundary conditions governing the dynamics of the overlying ic...

Atmospheric forcing of rapid marine-terminating glacier retreat in the Canadian Arctic Archipelago (2019)
Journal Article
Cook, A., Copland, L., Noel, B., Stokes, C., Bentley, M., Sharp, M., …van den Broeke, M. (2019). Atmospheric forcing of rapid marine-terminating glacier retreat in the Canadian Arctic Archipelago. Science Advances, 5(3), Article eaau8507. https://doi.org/10.1126/sciadv.aau8507

The Canadian Arctic Archipelago contains >300 glaciers that terminate in the ocean, but little is known about changes in their frontal positions in response to recent changes in the ocean-climate system. Here, we examine changes in glacier frontal po... Read More about Atmospheric forcing of rapid marine-terminating glacier retreat in the Canadian Arctic Archipelago.

The role of lithospheric flexure in the landscape evolution of the Wilkes Subglacial Basin and Transantarctic Mountains, East Antarctica (2019)
Journal Article

The role of lithospheric flexure in the landscape evolution of the Wilkes Subglacial Basin and Transantarctic Mountains, East Antarctica. Journal of Geophysical Research: Earth Surface, 124(3), 812-829. https://doi.org/10.1029/2018jf004705

Reconstructions of the bedrock topography of Antarctica since the Eocene–Oligocene Boundary (ca. 34 Ma) provide important constraints for modelling Antarctic ice sheet evolution. This is particularly important in regions where the bedrock lies below...

Cosmogenic-nuclide surface-exposure data provide important constraints on the thickness, extent and behaviour of ice masses in the geological past. A number of online calculators provide the cosmogenic nuclide community with a means of easily calcula...

Antarctic ice sheet palaeo-thinning rates from vertical transects of cosmogenic exposure ages (2019)
Journal Article

We present a nontrivial correlation between the enhancement of the Higgs-fermion couplings and the Higgs pair production cross section in two Higgs doublet models with a flavor symmetry, with implications for LHC searches. This symmetry suppresses fl... Read More about Antarctic ice sheet palaeo-thinning rates from vertical transects of cosmogenic exposure ages.
