The chronostratigraphy of Late Pleistocene glacial and periglacial aeolian activity in the Tuktoyaktuk Coastlands, NWT, Canada [PDF]

, 2006
Aeolian periglacial sand deposits are common in the Tuktoyaktuk Coastlands of Western Arctic Canada. Regionally extensive and thick aeolian sand-sheet deposits have been observed in two major stratigraphic settings: within a sand unit characterized by ...

Southern Ocean warming and Wilkes Land ice sheet retreat during the mid-Miocene

Nature Communications, 2018
Observations and model experiments highlight the importance of ocean heat in forcing ice sheet retreat during the present and geological past, but past ocean temperature data are virtually missing in ice sheet proximal locations.

Large-ensemble simulations of the North American and Greenland ice sheets at the Last Glacial Maximum with a coupled atmospheric general circulation–ice sheet model [PDF]

Climate of the Past
The Last Glacial Maximum (LGM) was characterised by huge ice sheets covering the Northern Hemisphere, especially over North America, and by its cold climate.

Translational Extracellular Matrix Spray‐Coating Approach for Large‐Scale Bioactive Surface Functionalization and Tissue Repair

Advanced Healthcare Materials, EarlyView.
A translational spray‐coating strategy that conformationally activates fibronectin and collagen via mechanical unfolding is presented. Microscale droplets enable uniform extracellular matrix (ECM) depositions on biomedical substrates and wound closure enhancement.

Contrasting the Penultimate Glacial Maximum and the Last Glacial Maximum (140 and 21 ka) using coupled climate–ice sheet modelling [PDF]

Climate of the Past
The configuration of the Northern Hemisphere ice sheets during the Penultimate Glacial Maximum differed to the Last Glacial Maximum. However, the reasons for this are not yet fully understood.

Multidecadal warming of Antarctic waters [PDF]

, 2014
Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat

Nature Communications, 2019
Accurate estimates of the past extent of the Greenland ice sheet provide critical constraints for ice sheet models used to determine Greenland’s response to climate forcing and contribution to global sea level.

Dynamics of Marine Ice Sheets

Procedia IUTAM, 2014
On short length and time scales, ice behaves as a brittle, elastic solid but on continental length scales and timescales of years or longer, ice flows as a viscous fluid. The West Antarctic Ice Sheet, for example, sits on bedrock that is 1–2 kilometres below sea level.
