Journal Article
Pan, L., Mitrovica, J. X., Milne, G. A., Hoggard, M. J., & Woodroffe, S. A. (2024). Timescales of glacial isostatic adjustment in Greenland: is transient rheology required?. Geophysical Journal International, 237(2), 989-995. https://doi.org/10.1093/gji/ggae095

The possibility of a transient rheological response to ice age loading, first discussed in the literature of the 1980s, has received renewed attention. Transient behaviour across centennial to millennial timescales has been invoked to reconcile appar...

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.

Missing sea level rise in southeastern Greenland during and since the Little Ice Age (2023)
Journal Article

The Greenland Ice Sheet has been losing mass at an accelerating rate over the past 2 decades. Understanding ice mass and glacier changes during the preceding several hundred years prior to geodetic measurements is more difficult because evidence of p...

Geological evidence of megathrust earthquakes along the Mexican Pacific coast relies predominantly on tsunami deposits. Records of coseismic relative sea-level changes are scarce even though such evidence can complement and constrain tsunami records,...

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...

Quaternary Science Reviews, 296, Article 107810. https://doi.org/10.1016/j.quascirev.2022.107810

Ice core records have long indicated that the Younger Dryas began and ended with large, abrupt climate shifts over Greenland. Key climatic features remain unknown, including the magnitude of warming during the Younger Dryas-Holocene transition along...
