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 PastThe 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 ...

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.

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

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.

Rapid Basal Channel Growth Beneath Greenland's Longest Floating Ice Shelf
Geophysical Research Letters, 2023 Nioghalvfjerdsfjorden Glacier (N79) is one of the two main outlets for Greenland's largest ice stream, the Northeast Greenland Ice Stream, and is the more stable of the two, with no calving front retreat expected in the near future. Using a novel surface

Impact of runoff temporal distribution on ice dynamics [PDF]
The Cryosphere, 2022 Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both increased length and melt intensity

On the physical basis for the creep of ice: the high temperature regime
Journal of Glaciology, 2020 This work quantifies the increased temperature sensitivity of the constitutive behavior of ice with proximity to the melting point in terms of dislocation mechanics.

Geophysical Research Letters, 2023 Sea ice modulates the energy exchange between the atmosphere and the ocean through its kinematics. Marginal ice zone (MIZ) dynamics are complex and are not well resolved in routine observations.

Annual Review of Fluid Mechanics, 2013 We describe the development of mathematical models of ice sheets, focusing on underlying physics and the minimal components that successful models must contain. Our review describes the basic fluid dynamical ice-flow models currently in use; points out numerous poorly understood thermomechanical feedbacks in ice flow; and describes the current, often ...
