Modelling the influence of marine ice on the dynamics of an idealised ice shelf

open access: yesJournal of Glaciology, 2023
Understanding the dynamic behaviour of ice shelves, specifically the controls on their ability to buttress the flow of ice into the ocean, is critical for predicting future ice-sheet contributions to sea level rise.

Decoupling of δ18O from surface temperature in Antarctica in an ensemble of historical simulations [PDF]

open access: yesClimate of the Past
Stable water isotopes recorded in Antarctic ice cores have traditionally been used to infer past surface air temperatures (SATs). During the historical period (1850 onward), observational data and good-quality ice core records overlap, yielding an ...

Dynamics and hysteresis in square lattice artificial spin-ice [PDF]

open access: yes, 2013
Dynamical effects under geometrical frustration are considered in a model for artificial spin ice on a square lattice in two dimensions. Each island of the spin ice has a three-component Heisenberg-like dipole moment subject to shape anisotropies that ...

The role of subglacial hydrology in Antarctic ice sheet dynamics and stability: a modelling perspective

open access: yesAnnals of Glaciology, 2022
Subglacial hydrology is an important component of the ice dynamic system in Antarctica but is challenging to investigate due to the large spatial scales of the catchment systems, the ice thickness, and remote location.

Modeling the Greenland englacial stratigraphy [PDF]

open access: yesThe Cryosphere, 2021
Radar reflections from the interior of the Greenland ice sheet contain a comprehensive archive of past accumulation rates, ice dynamics, and basal melting. Combining these data with dynamic ice sheet models may greatly aid model calibration, improve past

H11 meltwater and standard 127 ka Last Interglacial simulations suggest more modest peak temperatures for both Greenland and Antarctica: a multi-model study of water isotopes [PDF]

open access: yesClimate of the Past
The Last Interglacial (LIG) period, approximately 130 000 to 115 000 years ago, represents one of the warmest intervals of the past 800 000 years. Here, we simulate water isotopes in precipitation over Antarctica and the Arctic during the LIG, using ...

How the growth of ice depends on the fluid dynamics underneath

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Significance Landscapes, resulting from ice–water interactions coupled with solidification/melting, are ubiquitous in nature, yet most previous studies have not considered the rich fluid dynamics induced by water density anomaly underneath the moving ice

The importance of the weak: Interaction modifiers in artificial spin ices [PDF]

open access: yes, 2017
The modification of geometry and interactions in two-dimensional magnetic nanosystems has enabled a range of studies addressing the magnetic order, collective low-energy dynamics, and emergent magnetic properties, in e.g.

Assessment of the southern polar and subpolar warming in the PMIP4 last interglacial simulations using paleoclimate data syntheses [PDF]

open access: yesClimate of the Past
Given relatively abundant paleo-proxies, the study of the last interglacial (LIG, ∼ 129–116 000 years ago, ka) is valuable to understanding the responses and feedback of the Southern Ocean and Antarctica in a warmer-than-preindustrial climate.

Development of a low-temperature immersion microscopy technique for ice research

open access: yesAnnals of Glaciology, 2023
Perennial ice can be studied for many purposes, including paleoclimate records or rheological properties. For most of those purposes, the ice microstructure must be studied, often through optical microscopy.
