Evidence for a palaeo-subglacial lake on the Antarctic continental shelf [PDF]
, 2017 Subglacial lakes are widespread beneath the Antarctic Ice Sheet but their control on ice-sheet dynamics and their ability to harbour life remain poorly characterized.

Modelling dynamic ice-sheet boundaries and grounding line migration using the level set method
Journal of Glaciology, 2020 Computing predictions of future sea level that include well-defined uncertainty bounds requires models that are capable of robustly simulating the evolution of ice sheets and glaciers.

Glacial geomorphology of the central Barents Sea Implications for the dynamic deglaciation of the Barents Sea Ice Sheet [PDF]
, 2017 Contemporary climate change has resulted in great uncertainty in how glaciers and ice sheets around the Earth might evolve. It has long been appreciated that the contemporary West Antarctic Ice Sheet (WAIS) shares many similarities with the former ...

Antarctic ice sheet and oceanographic response to eccentricity forcing during the early Miocene [PDF]
Climate of the Past, 2011 Stable isotope records of benthic foraminifera from ODP Site 1264 in the southeastern Atlantic Ocean are presented which resolve the latest Oligocene to early Miocene (~24–19 Ma) climate changes at high temporal resolution (<3 kyr).

Quantification of the Greenland ice sheet contribution to Last Interglacial sea level rise [PDF]
, 2012 During the Last Interglacial period (~ 130–115 thousand years ago) the Arctic climate was warmer than today, and global mean sea level was probably more than 6.6 m higher.

High climate model dependency of Pliocene Antarctic ice-sheet predictions
Nature Communications, 2018 Ice sheet models forced by climate model output indicate ice-sheet retreat during the Pliocene, yet concerns remain regarding potential model bias. Here, the authors present results from the Pliocene Ice-sheet Modelling Intercomparison Project, and show ...

Tracer transport in an isochronal ice-sheet model
Journal of Glaciology, 2017 The full history of ice sheet and climate interactions is recorded in the vertical profiles of geochemical tracers in polar ice sheets. Numerical simulations of these archives promise great advances both in the interpretation of these reconstructions and

The speedup of Pine Island Ice Shelf between 2017 and 2020: revaluating the importance of ice damage
Journal of Glaciology, 2023 From 2017 to 2020, three significant calving events took place on Pine Island Glacier, West Antarctica. Ice-shelf velocities changed over this period and the calving events have been suggested as possible drivers.

Observing and Modeling Ice Sheet Surface Mass Balance [PDF]
Reviews of Geophysics, 2019 AbstractSurface mass balance (SMB) provides mass input to the surface of the Antarctic and Greenland Ice Sheets and therefore comprises an important control on ice sheet mass balance and resulting contribution to global sea level change. As ice sheet SMB varies highly across multiple scales of space (meters to hundreds of kilometers) and time (hourly ...

Modelling snow accumulation on Greenland in Eemian, glacial inception, and modern climates in a GCM [PDF]
, 2012 Changing climate conditions on Greenland influence the snow accumulation rate and surface mass balance (SMB) on the ice sheet and, ultimately, its shape.
