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
Small, D., Pittard, M., Whitehouse, P., Jones, R., & Bentley, M. (2019). Antarctic ice sheet palaeo-thinning rates from vertical transects of cosmogenic exposure ages. Quaternary Science Reviews, 206, 65-80. https://doi.org/10.1016/j.quascirev.2018.12.024

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.

Evaluation of Mumiyo Deposits from East Antarctica as Archives for the Late Quaternary Environmental and Climatic History (2018)
Journal Article

Evaluation of Mumiyo Deposits from East Antarctica as Archives for the Late Quaternary Environmental and Climatic History. Geochemistry, Geophysics, Geosystems, 20(1), 260-276. https://doi.org/10.1029/2018gc008054

Mumiyo deposits form in the vicinity of snow petrel (Pagodroma nivea) nesting sites and consist of fossil stomach oil (mumiyo), guano and minerogenic material. Here, we evaluate mumiyo deposits from the inland mountain ranges of central Dronning Maud...

Evidence for the long-term sedimentary environment in an Antarctic subglacial lake (2018)
Journal Article

Lakes beneath the Antarctic Ice Sheet are of fundamental scientific interest for their ability to contain unique records of ice sheet history and microbial life in their sediments. However, no records of subglacial lake sedimentation have yet been ac... Read More about Evidence for the long-term sedimentary environment in an Antarctic subglacial lake.

Late Holocene relative sea levels near Palmer Station, northern Antarctic Peninsula, strongly controlled by late Holocene ice-mass changes (2018)
Journal Article
Simms, A., Whitehouse, P., Simkins, L., Nield, G., DeWitt, R., & Bentley, M. (2018). Late Holocene relative sea levels near Palmer Station, northern Antarctic Peninsula, strongly controlled by late Holocene ice-mass changes. Quaternary Science Reviews, 199, 49-59. https://doi.org/10.1016/j.quascirev.2018.09.017

Many studies of Holocene relative sea-level (RSL) changes across Antarctica assume that their reconstructions record uplift from glacial isostatic adjustment caused by the demise of the Last Glacial Maximum (LGM) ice sheets. However, recent analysis... Read More about Late Holocene relative sea levels near Palmer Station, northern Antarctic Peninsula, strongly controlled by late Holocene ice-mass changes.

Lack of evidence for a substantial sea-level fluctuation within the Last Interglacial (2018)
Journal Article
Barlow, N., McClymont, E., Whitehouse, P., Stokes, C., Jamieson, S., Woodroffe, S., …Sanchez-Montes, M. (2018). Lack of evidence for a substantial sea-level fluctuation within the Last Interglacial. Nature Geoscience, 11, 627-634. https://doi.org/10.1038/s41561-018-0195-4

During the Last Interglacial, global mean sea level reached approximately 6 to 9 m above the present level. This period of high sea level may have been punctuated by a fall of more than 4 m, but a cause for such a widespread sea-level fall has been e...

East Antarctica hosts large subglacial basins into which the East Antarctic Ice Sheet (EAIS) likely retreated during past warmer climates. However, the extent of retreat remains poorly constrained, making quantifying past and predicted future contrib...

The East Antarctic Ice Sheet has relatively few field data to constrain its past volume and contribution to global sea-level change since the Last Glacial Maximum. We provide new data on deglaciation history and develop new relative sea-level (RSL) c... Read More about Ice sheet retreat and glacio-isostatic adjustment in Lützow-Holm Bay, East Antarctica.

Changes in penguin populations on the Antarctic Peninsula have been linked to several environmental factors, but the potentially devastating impact of volcanic activity has not been considered. Here we use detailed biogeochemical analyses to track pa... Read More about Past penguin colony responses to explosive volcanism on the Antarctic Peninsula.
