A comparison of the stability and performance of depth-integrated ice-dynamics solvers
The Cryosphere, 2022 . In the last decade, the number of ice-sheet models has increased substantially, in line with the growth of the glaciological community. These models use solvers based on different approximations of ice dynamics.

Ice Core Chronologies from the Antarctic Peninsula: The Palmer, Jurassic, and Rendezvous Age-Scales
Geosciences, 2022 In this study, we present the age scales for three Antarctic Peninsula (AP) ice cores: Palmer, Rendezvous, and Jurassic. The three cores are all intermediate-depth cores, in the 133–141 m depth range.

Decadal Scale Variability of Larsen Ice Shelf Melt Captured by Antarctic Peninsula Ice Core
Geosciences, 2022 In this study, we used the stable water isotope record (δ18O) from an ice core drilled in Palmer Land, southern Antarctic Peninsula (AP). Utilizing δ18O we identified two climate regimes during the satellite era.

Stochastic ice stream dynamics [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Ice streams form the backbone of the flow field of ice sheets. They are known to exhibit a complex spatiotemporal dynamics, which is largely not well understood. Understanding the controls on such dynamics is crucial to sea level change projections as well as to the interpretation of paleorecords.

Tracer Measurements in Growing Sea Ice Support Convective Gravity Drainage Parameterizations [PDF]
, 2020 Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modeling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice.

Geophysical Research Letters, 2023 Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting.

The internal structure of the Brunt Ice Shelf from ice-penetrating radar analysis and implications for ice shelf fracture [PDF]
The Cryosphere, 2018 The rate and direction of rift propagation through ice shelves depend on both the stress field and the heterogeneity (or otherwise) of the physical properties of the ice.

An Age Scale for the First Shallow (Sub-)Antarctic Ice Core from Young Island, Northwest Ross Sea
Geosciences, 2021 The climate of the sub-Antarctic is important in understanding the environmental conditions of Antarctica and the Southern Ocean. However, regional climate proxy records from this region are scarce.

Quaternary Science Reviews, 2020 Time-series analyses of satellite images reveal that sea ice extent in the Ross Sea has experienced significant changes over the last 40 years, likely triggered by large-scale atmospheric anomalies.
