Englacial Pore Water Localizes Shear in Temperate Ice Stream Margins [PDF]

open access: yes, 2019
The margins of fast‐moving ice streams are characterized by steep velocity gradients. Some of these gradients cannot be explained by a temperature‐dependent viscosity alone.

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

The effect of buttressing on grounding line dynamics [PDF]

open access: yes, 2018
Determining the position and stability of the grounding line of a marine ice sheet is a major challenge for ice-sheet models. Here, we investigate the role of lateral shear and ice-shelf buttressing in grounding line dynamics by extending an existing ...

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

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.

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.

Ice dynamics of union glacier from SAR offset tracking

open access: yesGlobal and Planetary Change, 2019
The Antarctic ice sheet is predicted to be the major contributor to sea-level rise during the XXI century. Therefore, monitoring ice dynamics of outlet glaciers in Antarctica is of great importance to assess future sea-level rise predictions.

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.
