GEORGIA: A Graph Neural Network Based EmulatOR for Glacial Isostatic Adjustment (2023)
Journal Article
Lin, Y., Whitehouse, P. L., Valentine, A. P., & Woodroffe, S. A. (2023). GEORGIA: A Graph Neural Network Based EmulatOR for Glacial Isostatic Adjustment. Geophysical Research Letters, 50(18), https://doi.org/10.1029/2023gl103672

Glacial isostatic adjustment (GIA) modeling is not only useful for understanding past relative sea-level change but also for projecting future sea-level change due to ongoing land deformation. However, GIA model predictions are subject to a range of... Read More about GEORGIA: A Graph Neural Network Based EmulatOR for Glacial Isostatic Adjustment.

Antarctic ice sheet paleo-constraint database (2023)
Journal Article
Lecavalier, B. S., Tarasov, L., Balco, G., Spector, P., Hillenbrand, C., Buizert, C., …Bamber, J. (2023). Antarctic ice sheet paleo-constraint database. Earth System Science Data, https://doi.org/10.5194/essd-2022-398

We present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic changes, for state-space estimation, and...

Relative sea level response to mixed carbonate-siliciclastic sediment loading along the Great Barrier Reef margin (2023)
Journal Article
Lin, Y., Whitehouse, P. L., Hibbert, F. D., Woodroffe, S. A., Hinestrosa, G., & Webster, J. M. (2023). Relative sea level response to mixed carbonate-siliciclastic sediment loading along the Great Barrier Reef margin. Earth and Planetary Science Letters, 607, Article 118066. https://doi.org/10.1016/j.epsl.2023.118066

The continental shelf along northeastern Australia is the world’s largest mixed carbonate-siliciclastic passive margin and the location of the Great Barrier Reef (GBR). Following sea-level transgression during the last deglaciation, extensive sedimen...

An ensemble of Antarctic deglacial simulations constrained by geological observations (2022)
Journal Article
Pittard, M., Whitehouse, P., Bentley, M., & Small, D. (2022). An ensemble of Antarctic deglacial simulations constrained by geological observations. Quaternary Science Reviews, 298, Article 107800. https://doi.org/10.1016/j.quascirev.2022.107800

The Antarctic ice sheet has the potential to make a significant contribution to future sea-level rise. Understanding this potential and making projections of future ice sheet mass change requires use of numerical models. Confidence in model projectio...

Reassessment of hydrate destabilization mechanisms offshore west Svalbard confirms link to recent ocean warming (2022)
Journal Article
Trivedi, A., Sarkar, S., Marin-Moreno, H., Minshull, T., Whitehouse, P., & Singh, U. (2022). Reassessment of hydrate destabilization mechanisms offshore west Svalbard confirms link to recent ocean warming. Journal of Geophysical Research. Solid Earth, 127(11), Article e2022JB025231. https://doi.org/10.1029/2022jb025231

The stability of methane hydrates at the feather edge of hydrate stability on the upper continental slope (UCS) is prone to ocean warming and relative sea-level (RSL) change. West of Svalbard, methane seeps on the UCS were initially proposed to resul...

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/s41586-022-04946-0

The 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.

Stability of the Antarctic Ice Sheet during the pre-Industrial Holocene (2022)
Journal Article
Jones, R., Johnson, J., Lin, Y., Mackintosh, A., Sefton, J., Smith, J., …Whitehouse, P. (2022). Stability of the Antarctic Ice Sheet during the pre-Industrial Holocene. Nature Reviews Earth & Environment, 3(8), 500-515. https://doi.org/10.1038/s43017-022-00309-5

The rate and magnitude of the Antarctic Ice Sheet (AIS) contribution to global sea-level rise beyond 2100 CE remains highly uncertain. Past changes of the AIS, however, offer opportunities to understand contemporary and future ice sheet behaviour. In...

Relative sea-level data preclude major late Holocene ice-mass change in Pine Island Bay (2022)
Journal Article

The rapidly retreating Thwaites and Pine Island glaciers together dominate present-day ice loss from the West Antarctic Ice Sheet and are implicated in runaway deglaciation scenarios. Knowledge of whether these glaciers were substantially smaller in... Read More about Relative sea-level data preclude major late Holocene ice-mass change in Pine Island Bay.

GPS-observed elastic deformation due to surface mass balance variability in the Southern Antarctic Peninsula (2022)

Geophysical Research Letters, 49(4), Article e2021GL097109. https://doi.org/10.1029/2021gl097109

In Antarctica, Global Positioning System (GPS) vertical time series exhibit non-linear signals over a wide range of temporal scales. To explain these non-linearities, a number of hypotheses have been proposed, among them the short-term rapid solid Ea...
