The dynamic tensile strength of ice and ice‐silicate mixtures [PDF]

Journal of Geophysical Research: Solid Earth, 1983
We determined the dynamic tensile strength of ice and ice silicate mixtures at strain rates of ∼104 s−1. At these strain rates, ice has a tensile strength of ∼17 MPa, and ice‐silicate mixtures with 5 and 30 wt % sand content have strengths of ∼20 and 22 MPa, respectively. These values lie significantly above tensile strengths of ∼1.6 MPa for ice and of

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)].

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]

, 2015
Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.

Brief communication: Reduced bandwidth improves the depth limit of the radar coherence method for detecting ice crystal fabric asymmetry [PDF]

The Cryosphere
Ice crystal orientation fabric strongly affects the viscous deformation of glacier ice. A popular technique to investigate ice fabric is radar polarimetry, often analysed using the coherence method.

Frazil dynamics and precipitation in a water column with depth-dependent supercooling [PDF]

, 2005
When seawater becomes supercooled, collections of small ice crystals, known as frazil ice, form and grow. A model of frazil ice dynamics is presented that deals explicitly with the buoyant settling of frazil crystals onto an overlying surface.

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.

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 ...

Ice nucleation under cirrus cloud conditions [PDF]

, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

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 ...

Assessing the continuity of the blue ice climate record at Patriot Hills, Horseshoe Valley, West Antarctica [PDF]

, 2016
We use high resolution Ground Penetrating Radar (GPR) to assess the continuity of the Blue Ice Area (BIA) horizontal climate record at Patriot Hills, Horseshoe Valley, West Antarctica.
