Validation of oil spill transport and fate modeling in Arctic ice
Arctic Science, 2018 Reliability of oil spill modeling in Arctic waters for response planning and risk assessments depends on the accuracy of winds, currents, and ice data (cover and drift) used as input.

Magnetic anisotropy and debris-dependent rheological heterogeneity within stratified basal ice
Journal of Glaciology, 2019 Basal ice of glaciers and ice sheets frequently contains a well-developed stratification of distinct, semi-continuous, alternating layers of debris-poor and debris-rich ice.

The Effect Of Rheology On Seasonal Sea-Ice Simulations [PDF]
Annals of Glaciology, 1990 On the seasonal time scales relevant to numerical investigations of climate, the rheology used in large-scale sea ice models significantly affects the ice thickness build-up and ice velocity fields. Plastic rheologies with a normal flow rule have been used to-date in seasonal dynamic thermodynamic simulations.

Biomass DNA: An Emerging Building Block for Advanced Materials
Advanced Materials, EarlyView.Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Exploring the conditions conducive to convection within the Greenland Ice Sheet
The CryosphereEnigmatic large plume-like features disrupt the radiostratigraphy within the Greenland Ice Sheet. Here we use the ASPECT geodynamics modelling package to test the hypothesis that convection is a viable mechanism for the formation of the large ( ice ...

Advanced Materials, EarlyView.This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Strengthening ice through cyclic loading
Journal of Glaciology, 2017 New experiments reveal that the flexural strength of fresh water, columnar-grained ice loaded normal to the columns may be increased by about a factor of two upon reversed cyclic loading at a frequency of ~0.1 Hz at stress amplitudes of 1.3–2.6 MPa.

Geochemistry, Geophysics, Geosystems, 2021 Accurate glacial isostatic adjustment (GIA) models are required for correcting measurements of mass change in Antarctica and for improving knowledge of the sub‐surface, especially in areas of large current ice loss such as the Amundsen Sea Embayment (ASE)

Continuum sea ice rheology determined from subcontinuum mechanics [PDF]
, 2006 [1] A method is presented to calculate the continuum-scale sea ice stress as an imposed, continuum-scale strain-rate is varied. The continuum-scale stress is calculated as the area-average of the stresses within the floes and leads in a region (the ...
