Magnetic monopole dynamics in spin ice [PDF]

Journal of Physics: Condensed Matter, 2011
One of the most remarkable examples of emergent quasi-particles, is that of the "fractionalization" of magnetic dipoles in the low energy configurations of materials known as "spin ice", into free and unconfined magnetic monopoles interacting via Coulomb's 1/r law [Castelnovo et. al., Nature, 451, 42-45 (2008)].

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

Journal 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]

Climate 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 ...

Marginal ice zone dynamics

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022
For the best part of my entire career, I have focused on the marginal ice zone, abbreviated to MIZ by most sea ice scientists. Defined perfunctorily by the National Snow & Ice Data Center as the part of the seasonal ice zone where waves, swells and other open ocean processes affect the sea ice, the MIZ habitually extends from the ice edge some 100 ...

Modeling the Greenland englacial stratigraphy [PDF]

The 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]

Climate 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 ...

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

Climate 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

Annals 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.

Bed topography and marine ice-sheet stability

Journal of Glaciology, 2022
This paper examines the effect of basal topography and strength on the grounding-line position, flux and stability of rapidly-sliding ice streams.

Evaporative controls on Antarctic precipitation: an ECHAM6 model study using innovative water tracer diagnostics [PDF]

The Cryosphere
Improving our understanding of the controls on Antarctic precipitation is critical for gaining insights into past and future polar and global environmental changes.
